Great video! I'm looking to rebuild my '03 545 before a long haul pulling about 2k lb trailer from Texas to Florida. Mine is a 4WD, so should be similar. Also thinking of a shift improvement kit.
Builders beware! There are two different second clutch molded rubber pistons out there. Put the wrong one in and have no apply. Quality control is out the door.
Hello une question ? faut il reprogrammer la boite après l'intervention ou il n'y a rien faire coté valise ? Hello, a question? Do you have to reprogram the box after the intervention or there is nothing to do on the suitcase side?
hello, I own a jeep cherokee liberty limited 2003 KJ 2.8 CRD, with my diagnostic devices (DRBIII emulator, Icarsoft) the following DTCs are still present despite their erase. It's P0740 TCC out of range, P2704, P0218, P0868, when I drive I feel vibrations, I can't say exactly if it comes from the gearbox...I'M NOT A MECHANIC. Your videos are very informative, which is why I am turning to you with the idea of having information from a specialist to help me solve this problem. The accelerator pedal is sometimes soft and sometimes not...is there a connection? I changed the oil, the filter but I did not change the flat filter. Thank you for your response, help and support
I've only rebuilt a couple transmissions before, but I recall part of the process being you need to soak your clutch rings in trans fluid for quite awhile before installing. Maybe these rings did not get that soaking and prematurely failed?
Details like that are exactly why a novice like me fail the first go-around😊 First junkyard tranny swap I did, I didn't know to prime the torque converter with as much fluid as possible. Those kinds of mistakes (that require hours of labor to fix) are the worst.🤦
My 545-rfe has been nothing but problems and it’s just a daily driver. 2003 ram 2500. It’s always 4th gear slippage for me. No more than 50 to 80k miles and it needs a rebuild.
Thanks for the video. Mine 545rfe has a very loud whining noise when accelerating in all modes - when in park, drive and neutral. I've disassembled it, inspected, replaced a couple of metal discs and installed completely rebuilt torque converter, but it didn't help. Have you ever faced this problem? What can it be? Any bearing or maybe pump?
Hi there, I have a question for a 545rfe expert…. I have a 2003 ram hemi with 35s. I like to cruise around 65 mpg on the highway, but sometimes it starts to lug down uncomfortably to like 1500-1600 rpm. I have heard these transmissions don’t like to kick down out of overdrive, that it would go into 2nd prime and burn up the o/d clutches. So I am curious what gear does it go into when I hit o/d off button? Does it kick down to 3rd? Reason I ask is because it is my understanding both 4th and 5th are overdrive ratios. Thanks
I thought this transmission had a fluid temperature sensor fitted? I have a 2005 Jeep Cherokee/Liberty 2.8 CRD which I think has this transmission. It has hard shifting when cold but is okay when it gets warm. I didn’t notice the sensor during the stripping.
The threads of the cannister filter are plastic. So be careful if you're jamming a screw driver through. Might as well have the correct tool if you're tearing down a trans.
Whats your opinion on the ats transmissions, 5 different stage options. Tired of the reman trans from the shop not paying 3 grand for another one to shit out at 40,000 miles. Stock 2007 dodge ram 1500 5.7
So what caused the clutches to burn up? If it was a fresh rebuild they should have been new. Are they not getting enough pressure to lock up properly? Bad parts used in the rebuild? Installed wrong? Too much power? You did a great job finding the issue but what caused it?
@@FrostbiteRam I would be worried about rebuilding it and throwing it in your truck without knowing that. Do you plan on replacing the valve body during your rebuild?
On these transactions the computer needed to be set in quick learn mode or it will fail prematurely. As the transactions wears the computer compensates. When trans is replaced the computer doesn't know it's new.
I’ve got 300k miles on my 45 and it’s stuck in I am assuming 2nd and 4th gear or whatever two gears it chose I’m not sure but I mean before it got stuck in those gears it shifted pretty damn good ngl
I've got a rfe Trans that shifts fine in first and second but wo n't shift into 3rd. We tried replacing the Trans control solenoid and speed sensors nada . Any ideas?
My 05 Durango is slipping under hard acceleration in first gear only. Have a pending P700 code. Great helpful video!!! Where can you buy the new parts for a rebuild?
Hi! I need some help! What is the different between the 545 and the 65RFE transmission? How can I identifie my transmission? I have 2012 RAM 1500 Lone Star crew cab with 5.7 HEMI engine and I can shift 1 to 6 manually. Thank you for your help!
You have a 65RFE if there’s 6 gears. The first number represents the number of forward gears. Your transmission has a label on the left side of the case just above the pan that identifies it also.
I totally think ure goin in the right direction I've heard when u drive a trans with x size stall it develop's grooves where u do your passes consistently then when u swap it goes into a different range and gets a different wear and things break.....thas jus what I've read on Reddit tho idk...💪🍻
Greetings! What have you heard about the Monster Transmissions monster in a box? Worth the $900 in parts? I just build a 399c.i. stroker with a custom torque cam, eagle top end, long tube headers, 11:1 compression. It's going in a 2007 ram 1500 4x4 on 35" mud tires. I really want to get this done right the first time. My tranny has not failed, but I figured I had better build the stock tranny before installing the motor. I expect the motor will make around 500-550hp. Not sure on torque numbers. Any guidance you can offer would be greatly appreciated.
From my experience there is no way to make a RFE trans hold power for long term use. But if your not running a power adder and drag racing it constantly it will hold up for a decent time. However the absolute best option is a good used factory trans or a new oem unit the rebuilds don't seem to work well from what I've heard and seen.
I don't know much about transmissions but doesn't the 2nd gear accumulator/spring look like it busted almost through the accumulator plate? Isn't accumulator plate failure a some what common issue with the valve body? Could a failure cause the burn up on the cluthes? Please correct me if I'm wrong. Just trying to learn...
Hello im gustavo from mty mexico y have a 4th generation ram 1500 mod 2012, i have problems because the neutral led no fuction its off in drive the truck, starts and fo forward an esoecialist tell me the range sensor but i dont know where is? You can help me?
Good video. But why did the clutches fail poor quality clutches? poor line pressure? Overpowered there's a reason they got smoked where all the passages from the valve body clean? So many questions why did the clutches fail?
Not really sure this trans was given to me from a friend who has a boosted ram and similar setup as mine. The transmission was supposed to be fully built but didn't hold long so he did a gm trans swap to his truck.
Man that would drive me nuts not knowing the actual reason it failed but I love your truck watch your videos all the time thanks for all the good information 👍
Looks like a lack of line pressure in the transmission. My guess is one of the check ball bearings was installed into the wrong channel or not installed at all.
That's what I've read is a common failure on these. And even after experiencing some slipping, a new valve body assembly can keep the unit running for many miles. Obviously, those clutches wouldn't have benefitted from such an easy fix.😊
does this transmission have the Neutral Safety Switch or The range sensor built into it? looking at buying a used dodge and owner thinks that this is the issue but i cannot find the sensor on the oustide of the transmission Please Help
Is the transmission that’s currently in your truck with 150,000 miles on it all stock? It’s impressive that it’s lasted that long. Mine has 197,000 On it but I don’t race... lol
I got a 545rfe in my 73 Challenger and it’s recently developed a shifting issue where it would feel like it’s hung in one gear and downshifts hard into second. It also has a little trouble going into 4-5 but once it’s there it’s fine .. Threw codes p0700 p0734 p0735 and i suspect the shift pack solenoids .. any help would be appreciated brotha !
@@FrostbiteRam burnt clutches are not the cause, they’re the result of another problem. There likely was not enough pressure exerted by the apply piston. This could be caused by leaking seals, an issue in the valve body, a leaking solenoid, etc.
Great video! but i have one small question: Is it possible to fill the transmission with dextron 6 (AmsOil) instead of ATF+4 aka dexron 3. How will friction discs behave in less viscous fluid?
I have tried it in a Dakota. It initially went into gear, within about2-3 minutes it started violently banging - it seemed like it was trying to go into 2 gears at once. I popped into neutral and stopped. Then it would only go into reverse. I thought I had destroyed the trans, but fortunately I went back to atf+4 and it was like nothing ever happened. These trans are VERY picky about type AND quantity of fluid. Little over/under full and they will slip, go into gear slow etc.
Most likely factory Mopar clutches. It seems to me that these transmissions work best left completely factory. Many had tried to upgrade them with aftermarket parts and most has still failed or failed faster than a stock transmission.
Frostbite Ram that’s probably true, I’m on my second trans but only because one of my lines came off on the freeway. My second one has been holding well though. I have a billet valve body that I’ll be installing next, not sure if it’ll help lol
I can't seem to find out how many quarts of transmission fluid goes back in. I've seen 14 I've seen 12. All I know is when I get it back in, I don't want to go back to the store.
Hey I have the same transmission in my 09 ram 1500 4.7. I'm going to do a stroker build, but I'm trying to determine what the stock trans can handle (hp and torque). My ideal torque is about 500 hp and torque on my build. What upgrades do you recommend for my 545RFE five-speed? Or would you even suggest a trans swap to the 65rfe or Zf 8 speed to be able to handle to additional power?
I'm putting a little bit more than that through mine and its still holding. If you stay around 500 Mark it will hold up pretty well if tuned and driven right.
@@FrostbiteRam your 545rfe is holding up on 500hp? I've the 545 fail a lot on anything over stock. Also have you heard of anyone doing an 8speed swap in the 3rd gen rams that is successful
Hey, I have the same transmission. It works great, but it does have a small annoying problem in the mornings. It takes about 15 seconds to build up enough pressure to move after you put it in drive. After that it's great the rest of the day. Do you know what might be causing this? Thanks in advance for any help you can provide
Change the canister filter. The pump is bleeding fluid back into the pan overnight. It may not be seated properly or the check valve could be faulty. Mine have all done it too some worse than others, but the filter swap usually fixes it.
@@codylapoint Thanks for the info. I changed both filters when I first bought the jeep at 135K miles and the problem did go away for about 2 weeks, but sometimes it will go for a few days without doing it anyway so I wasn't sure if it was related. Seems to do it more if Im parked on a incline overnight. I'm at 175K now so I think I'll change them again. Thanks again
I’m about to install a histall, shift kit, and upgrade the clutchs. I was calling around for pricing and two trans shops told me about the filters. One trans shop said to buy the dodge filters not after market ones. The aftermarket ones can cause the problem you’re talking about.
@@Itslikethat313 Yeah, both filters came from Mopar last time. Im ab to change them again. I mostly eliminated the problem by parking on a level part of ground beside my house at night
It probably failed after rebuild because he pushed it hard before the trans control computer learning procedure was completed, smoking the second gear, which is a very doggish gear to begin with.
Sometimes! Rebuilders forget or simply don't know ( yes there are some that don't. I've run into a few of them over the years) that You HAVE to soak all clutch disks in transmission fluid for a few hours at the very least before they get installed. So while I can't tell if that was what caused this particular problem, this is one reason I've seen some burn out pretty fast after someone rebuilt. Another reason can be due to the spacing in the trams is wrong. Another reason is ( if you saw him looking at the over drive stage Part.) the rings on the shaft may have gotten nicked or torn. While most of the time, if this has happened, it will be noticed very quickly as the transmission won't shift correctly . But also, if it's just a slight nick, it may take it a few miles before it shows not shifting properly. Then of course there could be a problem with fluid flow. Pump having something wrong with it and a number of other reasons too long to get into here. But yeah, I too wish he'd have told us what he thought the reason it burned up was.
It’s throwing another code as well p0700 transmission control system (mil request) it won’t shift past first in drive but you can manually shift it to second
@@GearHeadsRestorationsllc I did a 46re cope racing transmission swap fully built with manual valve body and transbrake. I have many videos on the swap
@@FrostbiteRam Thats a sweet build. I actually own a shop and do transmissions builds. I watch others now and leave good comments if the build looks good. Let me know how that one held up for you!
Thanks for the support Mopar fam i hope this video helps somebody out.🤙🙏
I guess I'm quite randomly asking but do anybody know a good site to watch newly released series online?
If the canister filter was loose would that let the pressure be weak and the transmission and car would not move at all
Subscribed. I have this transmission and will shortly be doing a rebuild. Thanks for taking the time to do this. 👌
Awesome thanks 👍

Nice, which kit will you be rebuilding this trans with?
Most likely factory Mopar clutches. It seems to me that these transmissions work best left completely factory. Many had tried to upgrade them with aftermarket parts and most has still failed or failed faster than a stock transmission.
Frostbite Ram that’s probably true, I’m on my second trans but only because one of my lines came off on the freeway. My second one has been holding well though. I have a billet valve body that I’ll be installing next, not sure if it’ll help lol

If racing from digs it can hold pretty well. But if roll racing and you let the trans kick down to many times it will not.

It depends on year but I believe the 8speeds have the computer as part of the transmission.

My ideal torque is about 500 hp and torque on my build. What upgrades do you recommend for my 545RFE five-speed? Or would you even suggest a trans swap to the 65rfe or Zf 8 speed to be able to handle to additional power?
I'm putting a little bit more than that through mine and its still holding. If you stay around 500 Mark it will hold up pretty well if tuned and driven right.
@@FrostbiteRam your 545rfe is holding up on 500hp? I've the 545 fail a lot on anything over stock. Also have you heard of anyone doing an 8speed swap in the 3rd gen rams that is successful
Sonnax line pressure booster, shift kit, better clutch packs.
Hey, I have the same transmission. It works great, but it does have a small annoying problem in the mornings. It takes about 15 seconds to build up enough pressure to move after you put it in drive. After that it's great the rest of the day. Do you know what might be causing this? Thanks in advance for any help you can provide
Possible air leak in pump perhaps. Try message cope racing on his UA-cam channel he may have a better idea.
Change the canister filter. The pump is bleeding fluid back into the pan overnight. It may not be seated properly or the check valve could be faulty. Mine have all done it too some worse than others, but the filter swap usually fixes it.
@@codylapoint Thanks for the info. I changed both filters when I first bought the jeep at 135K miles and the problem did go away for about 2 weeks, but sometimes it will go for a few days without doing it anyway so I wasn't sure if it was related. Seems to do it more if Im parked on a incline overnight. I'm at 175K now so I think I'll change them again. Thanks again
I’m about to install a histall, shift kit, and upgrade the clutchs. I was calling around for pricing and two trans shops told me about the filters. One trans shop said to buy the dodge filters not after market ones. The aftermarket ones can cause the problem you’re talking about.
@@Itslikethat313 Yeah, both filters came from Mopar last time. Im ab to change them again. I mostly eliminated the problem by parking on a level part of ground beside my house at night
It probably failed after rebuild because he pushed it hard before the trans control computer learning procedure was completed, smoking the second gear, which is a very doggish gear to begin with.
what caused it to burn out? on a fresh build. the burned disk are just the results of another problem.
Sometimes! Rebuilders forget or simply don't know ( yes there are some that don't. I've run into a few of them over the years) that You HAVE to soak all clutch disks in transmission fluid for a few hours at the very least before they get installed. So while I can't tell if that was what caused this particular problem, this is one reason I've seen some burn out pretty fast after someone rebuilt. Another reason can be due to the spacing in the trams is wrong. Another reason is ( if you saw him looking at the over drive stage Part.) the rings on the shaft may have gotten nicked or torn. While most of the time, if this has happened, it will be noticed very quickly as the transmission won't shift correctly . But also, if it's just a slight nick, it may take it a few miles before it shows not shifting properly. Then of course there could be a problem with fluid flow. Pump having something wrong with it and a number of other reasons too long to get into here. But yeah, I too wish he'd have told us what he thought the reason it burned up was.
@@tonym3675 thanks so hard to tell sometimes.
Mine doesn’t start to slip until third or 4th. Same issue or something to dig into and find out?
It will be worn clutches most likely
Frostbite Ram Easy to fix your self, all new trans, or a professional job?
@@jamesadkins805 I really don't think its that bad to do. But honestly its hard to beat a good used transmission on ebay or a salvage yard.
Frostbite Ram appreciate it
What material are the planetaries made out of?
Not sure really.
Is this the same trans in my 2012 5.7 ?
The 5 and 6speed is basically exactly identical.
Mines throwing a code gear 3 incorrect gear ratio any idea what it could be
Could be slipping clutches
It’s throwing another code as well p0700 transmission control system (mil request) it won’t shift past first in drive but you can manually shift it to second
What year model was this 545?
Yes
@@FrostbiteRam yes what? What year model is the 545RFE you were working on?
Do you have the rebuild video to this one?
Nope decided to swap to a fully built 46re
@@FrostbiteRamActually a better route!
@@GearHeadsRestorationsllc I did a 46re cope racing transmission swap fully built with manual valve body and transbrake. I have many videos on the swap
@@FrostbiteRam Thats a sweet build. I actually own a shop and do transmissions builds. I watch others now and leave good comments if the build looks good. Let me know how that one held up for you!
@@GearHeadsRestorationsllc awesome so far its been perfect
Your old converter stock?
Yes he hasnt upgraded it yet
Yes I still on stock converter 🥴
@@FrostbiteRam me too I wanna do a 2800 to 3000 myself....
I swear to god i can't find the line pressure sensor anywhere on my grand cherokee. It's like it's a whole different trans or something
Thanks for the help I’m do mines on my own it’s a lot cheaper
Lmfao if smells like a diff he Burt it up good
Oh yeah 👍
If nobody did a re-learn on the PCM after the trans was rebuilt... = toast
not really lol
Sounds like crickets in the background
full rebuild here ua-cam.com/video/Wt00u3nVo2Y/v-deo.html
I am probably going with a cope trans
I got up to 300k miles before my RFE transmission started to show problems
Wow this was tough to watch, you don't have a glue what your doing.
Lol🤣🤷♂️🍻
came cuz mine is doing the hokey pokey lol 198k all original
Guess we still dont know why it hapend just the resut of what happend. Put new ones in and it will just do it again because thats not why it happend.
Because it's junk that's why lol
Did not address what the title states
So it fails after a rebuild and you blame the transmission and not the builder? Lol
Nobody has had any luck with rebuilt rfe trans
@@FrostbiteRam I heard it was bad but didn’t know they were that bad
Best option is new unit or a unopened used junkyard trans
I have a 2011 ram R/T with transmission codes p0734 p0869 p0935 if anyone can help or had similar issues I’ll appreciate it
Go check out high performance rfe rams on Facebook
734 is gear ratio error in 4th idk bout the others
.
Horrible video. Did not go over most common problems. Did not tear apart fully. Do better.
😂😉
@@FrostbiteRam what are you winking at?
This video is lacking. You could have done better.
Another amateur.
🤣🤣🍻
