    Excellent video. a few points... 1) When the cooler bypass valve is closed, the fluid won't go to the cooler, and when it's open, fluid goes through. 2) If you're just doing a fluid level check without maintenance, the cooler bypass being open or closed won't make a difference as it will remain filled with no air one way or the other. If you' have done maintenance, then driving around until the fluid temp is 180F or higher would ensure that the cooler has been filled.

    John, I think the bypass valve will be a 3 port device providing a "constant volume" system whereas a 2 port valve will provide a variable volume system. If it is indeed a 3 port valve then the transmission oil volume does not vary regardless of whether the valve is open or closed, it simply either flows through the cooler or bypasses the cooler. This is basically very much like what is used in HVAC control and a constant volume prevent head/pump pressure increasing whereas a 2 port system tries to pump against a dead end and the head increases. I'm not sure I've explained it precisely enough but the fundamental is to ask the ZF guy whether the bypass valve is 3 port or 2 port. If 3 port then all is good and no need to worry about oil volume because the volume is constant. As an aside what a cack eyed system ZF seem to have created!

      I realize I’m 5 years down the road but hopefully this still helps someone. While what you’re saying is over my head I think I just confirmed what you’re saying. I just had to replace my cooler lines. I pulled off the bypass valve. With the “to cooler” side of bypass valve plugged I can blow through it blowing into it from the from transmission side. Also with both sides of the return from the cooler completely plugged I was able to blow through the side with the valve. So evidently the valve does NOT 100% close. If I’m able to blow air through it with my lungs I would guess those lines would fill up in just a couple minutes of run time at most.

    Dealing with hydraulics for thirty years on a daily basis you would need to determine if the cooler lines do drain back while the bypass valve is hot, if so there would be no true way of checking the fluid level because the fluid would drain back every time the engine is shut off while hot, however if the cooler is isolated during the ignition off position the cooler would stay full, You did a great job with this video by the way, very detailed!

    Presumably IF the transmission pan was drained when the engine was NOT above 160 then the bypass valve was closed and no fluid drained back into the pan and SHOULD not be affected by the temperature increase later.
    Notwithstanding this it would be advisable to double check after it has been run hot and the bypass valve open but I would NOT expect it to be low IF the bypass valve is working correctly

    This guys knows his stuff!
    By the way; these combined AC Condensers/Transmission coolers are known to crack and leak refrigerant, PAG oil and dye at around 100 000 Kms. Drivers will hear the "hiss of death" while driving with the AC on. It's a common issue with all Chrysler/Jeep/Dodge brands (this part is common) and the combined condenser needs to be replaced (there's a few videos on youtube about it and how to complete it). The replacement of the condenser is relatively simple, but i doubt any technician/mechanic will complete the trans fluid check after completion of the job. If it's happened to your CJD vehicle, and you have a new A/C condenser, check your ZF 8HP transmission fluid after the repair. It's NOT a required step in the standard A/C condenser repair in the standard repair manual. Your AC will be nice a cool but the transmission may potentially be low on fluid and may lead to premature failure.
    Keep up the great videos.

    Great information John very well explained. I installed a trans dipstick and tube on my 2011 F 150 with the 6R80 trans. No more having to play around under the truck next to that hot passenger side converter when checking the fluid level. In my view all manufactures should have an electronic display for the operator of the vehicle to check the transmission fluid level or at least a easily accessible dip stick.

    • @WeberAuto
      @WeberAuto  8 років тому +4

      Thank you! and thanks for your feedback. I was not aware that you could retrofit a 6R80 with a dipstick tube to replace the little short one under the truck. Dipsticks can lead to other problems that are now eliminated. 1st. Their accuracy has always been temperature sensitive. 2nd. They allow incorrect fluids to be easily installed. If the special fluid for this transmission is $43 USD from the Chrysler dealership and some generic fluid is $3.59 at the local auto parts chain, most people will buy the $3.59 oil because they may think that all fluids are the same, the price is the only difference. Obviously this would lead to transmission damage operational concerns. Best wishes!

    My ATF fluid research has led me to discover the following information. I document it here as well as on several Wikipedia pages I created/modified on Mercon, Dexron, Mopar, and Toyota automatic transmission fluids.
    Lifetime Fluids and Dipstick-less Transmissions:
    The 1967 Ford Type-F fluid specification was intended to produce a “lifetime” fluid that would never need to be changed. This is the first of many Ford “lifetime” fluids. The 1974 Ford Car Shop Manual reads "The automatic transmission is filled at the factory with "lifetime" fluid. If it is necessary to add or replace fluid, use only fluids which meet Ford Specification M2C33F. Many other transmission manufacturers have followed with their own "Lifetime" automatic transmission fluids".
    To understand how a fluid can last a "lifetime", a study of the 1939 Chrysler Fluid Drive Fluid is needed. The November 1954 edition of Lubrication Magazine (Published by The Texas Company, later known as Texaco) featured a story called "Evolution of the Chrysler PowerFlite Automatic Transmission". This article described the fluid used in the 1939 Chrysler Fluid Drive and its subsequent revisions and enhancements through 1954.
    A section of the feature described the lubrication of the Fluid Drive's fluid coupling, reads "The fluid drive fluid coupling is par­tially filled with Mopar Fluid Drive Fluid, a spe­cial highly refined straight mineral oil with a viscosity of about 185 SUS at 100° F., excellent inherent oxidation stability, high viscosity index (100), excellent ability to rapidly reject air, very low natural pour point ( -25° F.), ability to ade­quately lubricate the pilot ball bearing and seal surface, and neutrality towards the seal bellows.
    The fluid operates under almost ideal conditions in what is essentially a hermetically sealed case, the small amount of atmospheric oxygen initially pres­ent being removed by harmless reaction with the fluid so as to leave a residual inert (nitrogen) atmosphere. As a consequence, it has not been necessary to drain and replace the fluid, and the level-check recommendation has been successively extended from the original 2,500 miles to 15,500 miles and finally to "never" - or the life of the car.
    Since drains and level checks were not only unnecessary but frequently harmful ( through the introduction of more air, and seal-destroying dirt) Chrysler eventually left off the tempting level­ inspection plugs. This mechanism is therefore one of the very few that is actually lubricated for the life of the car. There are now myriad examples of couplings that have operated well over 100,000 miles without any attention whatsoever and were still in perfect condition when the car was retired."
    Umbrella Style Automatic Transmission Air Breathing Suppressor (TABS) from a 2017 Chevrolet Bolt EV
    Any automatic transmission fluid will last longer if the transmission case could be hermetically sealed, but transmissions have several potential entry points for air:
    1. The Dipstick Tube. Any transmission with a dipstick tube has the potential to let additional oxygen into the transmission through a dipstick or dipstick tube plug that is not fully seated in the tube, or through the process of using the dipstick to check the fluid level. Many modern transmissions do not have a dipstick, they have sealed transmission fluid level check plugs. By removing the dipstick, the transmission manufacturer has also removed a potential entry point for oxygen; this reduces the potential for fluid oxidation. A sealed transmission will have longer transmission fluid life than a non-sealed transmission.
    2. The Transmission Vent. Transmissions need vents to compensate for internal pressure changes that occur with temperature changes. Without those vents, pressure could build resulting in seal and gasket leaks. Older transmissions had large vents with not much more than a steel wool filter to keep out larger contaminates. The large vents allowed for easy inlet and outlet of air which results in additional oxygen being introduced into the transmission. Oxygen reacts with transmission fluid and can cause oxidation, rust, and corrosion. Ford and other transmission manufacturers have learned to use smaller vents with one-way Transmission Air Breathing Suppressor (TABS) valves in them to prevent oxygen entry into their transmissions.
    Any automatic transmission fluid will last longer if it comes from an unopened container
    1. Containers storing automatic transmission fluid (ATF) should always be sealed; if exposed to the atmosphere, ATF may absorb moisture and potentially cause shift concerns.
    2. When performing repairs on ATF-equipped transmissions, it is important to use only new, clean ATF when refilling the transmission. Never reuse ATF.
    Lifetime automatic transmission fluids made from higher quality base oil and an additive package are more chemically stable, less reactive, and do not experience oxidation as easily as lower quality fluids made from lower quality base oil and an additive package. Therefore, higher quality transmission fluids can last a long time in normal driving conditions (Typically 100,000 miles (160,000 km) or more).
    The definition of 'Lifetime Fluid" differs from transmission manufacturer to transmission manufacturer. Always consult the vehicle maintenance guide for the proper service interval for the fluid in your transmission and your driving conditions. According to the Owner's Manual of a 2018 Dodge Charger with "Lifetime Fluid" and a ZF 8-speed automatic transmission, the automatic transmission fluid, and filter never needs to be changed; however, ZF, the manufacturer of the ZF 8HP automatic transmission indicates the fluid has three different fluid service intervals depending on the driving style. ZF recommends a transmission oil and filter change every 62,000 miles (100,000 km) or after eight years at the latest.
    1. Normal Driving ZF Automatic transmissions are maintenance-free and filled with specially developed partially synthetic ATF oils. Maintenance-free fills are intended for normal operating conditions.
    Under "Normal" driving conditions, the automatic transmission fluid never needs to be changed (See age restriction below).
    2. Severe Driving Driving at very high operating temperatures can result in accelerated aging or increased wear of ATF oils. In the case of above-average operating conditions, such as:
    Driving with high transmission fluid temperature
    Frequent freeway driving in the upper-speed range
    Offensive or sporty driving style
    Frequent trailer operation (towing)
    Under "Severe" driving conditions, it is recommended to refresh (change) the oil and filter of the automatic transmission every 62,000 miles (100,000 km).
    3. Eight Years Old
    ZF recommends a transmission oil change after eight years at the latest.

    Additional Information:
    1. ZF recommends safely tilting the vehicle towards the driver's side to add an additional 0.5 liters of fluid to compensate for the transmission cooler bypass valve issue discussed in this video.
    2 You must use the correct fluid in this transmission. The fluid must meet ZF-LIFEGUARDFLUID 8 (ZF No. S671 090 312) specifications. See aftermarket.zf.com/remotemedia/lol-lubricants/lol-en/lol-te-ml-11-en.pdf
    3. Please turn off your traction control system before performing this procedure.
    As an automotive professor, I hear from a lot of people and students who have a negative reaction to this video and wonder why they took away the dipstick. Think about this: if a dipstick is so easy to use, you should be able to answer all of the following questions:
    1. At what temperature is the "cold" mark accurate?
    2. At what temperature is the "hot" mark accurate?
    3. What temperature does the dipstick even refer to? Outside air? Coolant temperature? Transmission fluid temperature?
    4. How will you measure that temperature?
    5. If the fluid is within the cold mark area marks when it is "cold", is the fluid level okay?
    6. if you live in a cold climate area like Alaska, is the "cold" level accurate there? What if you lived in a hot climate area like Central America, is their "cold" mark accurate?
    If you cannot answer all of the previous questions, should you be using a dipstick? See my dipstick video here: ua-cam.com/video/s-tHJ2Q_BbA/v-deo.html

      @WeberAuto the procedure says "86-122 degrees F (30-50 degrees C)" which is a pretty good range of 40F - that could be applied to the "cold" dipstick low mark fudge when car has been sitting overnight... the dipstick could list temperature for Hot as well - some cars (not my BMW) do have tranny temp gages. dipstick would make it trivial to check for color/condition as well.

      THANK YOU!!!! I read the ZF instrucions and saw the step about "overfilling" but couldn't figure out HOW this was done. Though according to many comments here, this is actually an unnecessary step on the RAM because the bypass valve system leaves fluid in the condenser anyway. Also - isn't this same system also warming the transmission such that the valve should be open anyway when cold to draw in engine heat to the transmission?

    Hello Prof Kelly, considering the oh so high cost of that trans fluid I think I'd skip the first step and proceed right to the second proceeded by a high temp run and cool down and then proceed from there depending on the results. As your video went on to the bypass valve discussion, why in the heck did manufactures remove the dip stick that was always there on older vehicles? Cost reduction, to keep people from being able to do it themselves? It used to be so simple, run and drive the vehicle, get it up to the desired temp and then check the dipstick. I really don't understand why that still couldn't be possible. But then I am 69 years old and probably don't understand the "new" way of doing, looking at things.

      If you paid attention to such, it started pretty empty. You then fill it until it starts to over flow and plug it when the flow stops > Run it > check. Any flow THEN is over flow, and not ALL as you mindless lot seem to believe.

    Seems like a trans fluid check should justify at least an hour of shop time. You make very good points about the bypass valve. It's concerning that a closed valve won't permit a complete change of fluid, especially when service is done by a shop trying to keep cost to the consumer low. Not only does it take more time to do it right, you also have to replace more fluid at astronomical prices. I hate it when the most economic alternative is to call the junk yard.

    Hey John, Great vid. I am curious why you're worried about the oil cooler bypass? I would have to believe that the when the valve is in bypass, the oil in the cooler is trapped and can't bleed back. If it's bypassing the cooler, how could the oil in the cooler circulate back? Thanks for your thoughts on this.

    • @WeberAuto
      @WeberAuto  8 років тому

      The oil cooler bypass opens when the fluid hot. If you shut off the engine while the fluid is hot, some of the fluid can drain back into the transmission. Then the fluid and bypass valve will cool down. This will leave open pockets of air in the cooler until the valve opens again. Thanks for the feedback.!

      @kodiekarmire1979 7 років тому +2

      I agree with cmbenson1911, there almost has to be a way to keep the fluid in the cooler to keep the levels correct. My guess is that it isn't controlled by temperature alone, I would hope it requires the fluid pressure to open it as well so as soon as you shut it off and the pressure drops it closes the valve.

  • @derekkchung

    There are 2 lines leading to the cooler (on top of the condenser you said). Can we disconnect the one of those 2 connections and connect one end to a funnel and another end to a drain pan. (We need to know which one is ingress and egress). Start the engine and let it warm up so that ATF comes out (assuming it has that aluminum thermo value). Keep on adding new ATF to funnel while watching the amount going to the drain pan. At the end, add a bit more and reconnect the disconnected line to the cooler and do a final level check at the tranny refill plug? 8HP has 8-9 quart total ATF capacity?

    Very helpful information, sir! I just changed the pan/filter and replaced some fluid on my ‘17 Durango and even the ZF service procedure that I was using did not include that but about the thermostatic bypass valve. It did, however, say to overfill by 0.5qt if trans cooler is present. But there is no way to overfill without having it leak out.
    I drove the Durango shortly after the fluid change and noticed a slight “whining” sound on acceleration, indicative of an underfill. I’ll check the fluid level again in the morning and add as necessary. This could also explain the slightly elevated trans temp of 190-194 as opposed to 170’s-180’s that I’d normally see. I just hope I didn’t do any internal damage!

    If the transmission cooler bypass doesn't close until 160 degrees and you are supposed to test the level of fluid between 86-122 degrees F then how are you ever supposed to know the correct level of the fluid with the plug out? Maybe the fluid level check is supposed to be done with fluid out of the cooler lines after it cooled down and the fluid in the pan already compensates the fluid used by the cooler lines... ? If you try to pull the plug with the engine off fluid definitely comes out. That's what I experienced after my first service on the transmission in my 2015 Ram 1500 4x4 after 128000 miles....

      LOL ! Took my Ram 1500 to the dealer to check the upper ball joints and trans as it is ' slipping ' . Was charged $100.00 to check trans level and tell me the upper ball joints are bad( Knew this already ) . Talked to the mechanic and was told the trans hadn't thrown any codes and wasn't physically checked as it takes two people had to be cold and is a pain to check. . . . . Sitting overnight prior to being pulled into this shop wasn't cold enough I guess ? Then sitting in the shop all day and needing to rescheduled to do what wasn't done on the first scheduled appointment. What is a pisser is the fact I'm a retired ASE master mechanic who is now disabled and physically unable to do the work but there is nothing wrong with my mind or how to read a time / labor guide . Oh by the way the upper A-arms were in stock to do the job , and the vehicle was approved by the warranty company to perform the work . Oh , I forgot to mention something as yet to be seen but I suspect I will be' surprised ' with . The transmission fluid whether added or changed etc will be deemed a ' service ' to be charged outright and not covered by warranty if Dodge service is like Toyota's service . I'm waiting to see as already I have had the expense of a rental vehicle , a hundred dollar deductible , another rental charge upcoming plus who knows if the work will be completed when it is returned to be performed again at the designated time ? Actually the night before as was required on the last appointed visit for repair . . Still better than the GM dealer in Gainsville though . They will lie send you back out after cheating the insurance company for work not done in an unsafe jerry rigged vehicle so you'll come back time and time again . Second time disabled and all , I located purchased parts , made repairs , video's the whole thing even the air suspension springs that weren't replaced along with the actuator or sensor arms that were jerry rigged with wire ties and sent old parts along with video to the IG and the insurance company I'd purchased the extended insurance plan through . My be going that route again it seems .

      I don't know anything about that. I do know that the ZF fluid for this transmission has an additive similar to limited slip differential additive. It allows the clutch packs to slip, on purpose, as part of normal transmission shifting operation. Regular ATF does not have that additive. The ZF fluid looks more like gear oil than ATF. To me, it would not be worth using any other fluid than the exact fluid that ZF calls for. Thanks for your feedback. Best wishes!

(you add the oil FIRST like a safety measure only to prevent damage JUST FOR THIS TEST!)... once you do the 4218 steps to get the fluid up to temperature and through all the gears... you open the plug again and if oil drips then there's too much.. if none drips then add.

    So the bypass valve is also a "purge valve" so that when the temp cools down it sends the fluid that's in the lines & condenser back into the transmission? I would think there would be fluid in there the whole time and therefore the level would be the same regardless of the electrostatic valve being open or closed...... Am I missing something?

There are too many variables to get wrong for a service industry that thrives on getting vehicles in and out of the dealership garages fast.

I replaced a radiator on a 2015 grand Cherokee and disconnected the transmission lines from the cooler to get the radiator out and i lost ~0.5 quarts from the cooler. Service manual states that cooler holds 0.5-0.7 quarts. So if you check after repair without bringing to normal operating temp the level will be off. So repair-drive to normal temp-let cool down-check level
