Please rebuild! I'm doing one of these right now out of my Jeep and I really could use the help!
Plz help I need to knw
How many more quarts I need I'm at 6th one now
PLEASE do a build video including tips for upgrades to improve strength and reliability. This is a great quality informational video.
Input received.
Thank you.
Amazing. I couldn’t have been more happy with this in depth view, with such great knowledge and experience, for these transmissions which is hard to find these days. Some people post videos of these transmissions but aren’t at all as in depth and or experienced. Thanks!!
You guys are simply amazing. I love the way you explain every part so thoroughly. It's very helpful and very improves my life. Thank you so much!!! Greetings from Scotland 🤠😍🤩
Glad you're enjoying the videos. You're very welcome!
Positive feedback is always appreciated. Thanks for dropping us a line.
Excellent information, probably the best out there, can't wait for some build videos.
The positive feedback is much appreciated.
Build videos are in progress (TH400). Stay tuned.
Thanks for dropping us a line, Ken.
Man this was great. I need the reassembly now
AMAZING video. I was giving up on finding a good quality video on this transmission when I found this one. Not only is the production quality good its some of the best on UA-cam. Subscribed
Glad you enjoyed it! Glad you found the channel.
@SouthpawAutoworks You guys are awesome man. Did yall end up making the rebuild video on this trans?
Wow friend. Your video is very good. Really grateful from CHILE 🇨🇱 It helped me learn how to untie an Automatic Transmission. I bought it especially to disassemble and learn how it works. I have a 1996 Dodge Dakota 3.9 42Re Thank you so much.
Awesome video!!! My jeep Grand cherokee zj 5.2 died. Im doing this job at my garage right now, and the rebuild video will be very appreciate!
Thank you very much. Excuse my English. Greetings from Montevideo, Uruguay.
Fantastic content! I totally support the build video, please go ahead. I would purchase all I need to rebuild it from you. Thank you for doing this!
Thank you for your input.
The positive feedback is appreciated.
Thanks for dropping us a line.
Yes Please ! 🥺 Hopefully a 44re and MAYBE 🤔 talk about how to beef up the transmission just enough for better towing or also about how choose a better transmission cooler or ways to keep oem version healthy
Another GREAT piece of work, I liked the shots of Robert in there, felt like a "behind the scenes" kind of thing
Right on!
I have a 2003 Jeep Cherokee with the 42RE. Having problems with the shift from 1st to 2nd and then a jolt to 3rd then neutral. But, it doesn't happen all the time. One morning I can drive away and the transmission shifts perfectly and it works fine for a week. Then the next morning it would act up again. But, when it worked it would shift perfectly. I've changed all the solenoids and accumulator spring which initially was broken. Had some improvement, but the same shifting problem still exists. I have noticed a faint whine after I put it into drive and start to coast, this only happens when it is acting up. I would tear into it if I had clue. Great video, you are teaching me allot !
Thank you for this video! very well done. please make the sequel! . I want to rebuild my 44re with beef up components
Noted. Thanks for your comment.
Another vote for the rebuild video. Would be curious to see 44RE components (or tips for upgrades) going into the 42RE housing. Thanks for the content!!
Input received. Thank you.
Definitely like to have my transmission on my Jeep rebuild by you guys. How do I go about that. Also what upgrades are there on this transmission.
Please make a build video! This was super helpful
Input received. Thank you.
Great video of the 42re/a500 transmission teardown. Would love to see a rebuild of this transmission as I have a a500 in a 1994 dakota that I need to rebuild.
Been a mechanic most of my life, but have never rebuilt an auto. I have a 44RE and for a while has shown it’s age. Recently I had one of the solenoids replaced. The one that controls shifts from 1st to 2nd, if my terminology is correct. The other day things went bad. It’s would rev up a little to much in first and not shift. Got it to shift by switching shifter positions. Then I experienced slipping. Now it has a real bad whining/squealing while parked in R N D 2 1. Increasing the revs in the respected gear, it kind of goes away, and makes what sounds like a hydraulic bypassing type sound. Like a power steering pump bypassing. I remembered days before experiencing a pulsing in acceleration whiling backing into driveway. Thanks for your video. I may attempt to rebuild it for the experience.
Caleb, I've been meaning to fire back...
Mechanic most of your life...right on. Rebuilding it for the experience would be really cool.
The whining sound has me leaning towards fluid level. Could also be an issue with the filter.
Fluid Level:
Many transmissions of this era, can be checked with the transmission in Park. This transmission, however, must be checked in Neutral (there are exceptions). With the trans shifted into Park, the TC (torque converter) is not fed oil. However, with the trans shifted into Neutral, the VB (valve-body) now sends oil to the TC. As the converter fills with oil, the oil level in the oil pan will drop. This is normal operation.
So....if the fluid level is checked, with the trans in Park, it'll give a false reading. It'll look higher than it actually is.
Note: The aftermarket sells a PR (Pressure Regulator) Valve that provides full-time lube...which sends oil to the TC, even with the trans shifted into Park.
***More details***
There's a solenoid block, that contains two solenoids mounted to one mounting plate (piece of metal, with a gasket). One solenoid is for the 3-4 up-shift/down-shift. The other solenoid is for TCC (torque converter clutch).
In some ways, this trans operates like an old school 3-speed.
1st, 2nd, and 3rd gear, are controlled by shift valves that are influenced by governor pressure and throttle pressure. The older Chrysler 3-speed transmissions utilized a governor (bolted to the output shaft). However, these later model 4 speeds did away with the governor (not always true...more details posted below). The governor was replaced by a governor solenoid. This is the metal solenoid that lives by itself, on the VB. The solenoid "creates" oil pressure, and sends it to the shift valves....just like an old-school output shaft mounted governor, used to do.
4-speed Chrysler transmissions, of this era, use the governor solenoid. However, some models still use the old-school governor. The naming of the trans tells which way the trans is set up.
For example:
47RE vs 47RH.
"E" stand for electronic (solenoid).
"H" stands for hydraulic (old school governor).
awesome content! thank you!
Thank you for great video teardown 👍
You bet!
Awesome job!!
Definitely looking forward to the torque converter video.
You and me both!
Thanks for dropping us a line.

Hello saludos desde Ecuador excelente tutorial
Thanks for the video!
You bet!
Great video.
Appreciate it.
I’m a little late but I’d love to see a rebuild and upgrade video on this transmission. I’m wanting to tear into mine and an in depth video on it like this one would help greatly
Input received.
I'd love to see a rebuild video by you guys. Seems like a lot more head-sense coming from SouthPaw. I dont have a trans need right now, but I have owned 7 Jeeps, all using the 42RE - except now I have 3 4wd and one 2 wheel drive. (I know, I cant help it - love those 4.0L. and I just know this jeep so well)
The 2 wheel slips a little in a couple of scenarios. Sometimes when I back out of the driveway, and shift to drive it may hesitate and then catch. The other scenarion always happens at the same stop light in town. I am turning left and then it slips a little a little after take off and into the turn. There are other random times, but because of the occurrence at the same locations, leads me to believe its an adjustment, or solenoid or something. I have driven this unit 400-500 mile trips and had no issues, so I dont think its a rebuild, but could be wrong.
One other question. On the 4wd 4re, is there a way to beef it up a bit? I note he was saying the clutches are fewer in the 42re vs the 44re. Is there a way to add more clutches to get a little more beefyness?
Thanks man - !!!
Gracias!!!!
Amazing 😊 i have question about drum overdrive direct because in my 42re the wave ring is crank and damage this drum. I onlynhave drum for bigger clutch pack from different gearbox. Can i use different drum and add few friction and steel ?
I would like to see an assembly video of the 42/44RE by you guys, specifically interested in setting up the clearance in the OD clutch.
Copy that.
Definitely a good video! I have a 42re that I rebuilt, and i was wondering about a problem I am having the reverse lights now stay on in all gears. Very disappointing! Is there any thoughts to a remedy? Thanks wish this video was up a yr ago ha ha but great job!!
Remember he said that there were 3 different neutral safety switiches sending info to the computer and to the reverse lights. I would look at that. Maybe yours is shorted or the wrong one.
Great video love it but I have a request. Would you tell me why I have a no down shift from 2nd to 1st intermittently sometimes it wants to take off in 2nd, most of the time it's fine. I have a 1995dodge dakota 3.9L v6. Any information would be appreciated my name is Leonard. This transmission hasn't been rebuilt has 94000 original miles on it.
My wavy snap ring broke or the second one. I can replace those without worrying about the large spring ?
How can i send my 42re from my jeep to get rebuilt by you guys? ive been wanting it to be rebuilt but the trans guys here dont know know them like you guys
Can someone tell me if the 44s overdrive will work on a 46re? I've built a 46 but it was 4x4 and hoped to rebuild the 2wd overdrive in my 98 5.2 and bolt it to my 46...
Hello friends, very good video, I am writing from Santiago de Chile. Do you know where to buy an automatic transmission for a Jeep Grand Cherokee Laredo WJ 2002 4.0 the 42RE please or where do you recommend buying one? Considering repairing it here in Chile, I think it would be more expensive than buying a refurbished... I would really appreciate a recommendation... Thank you very much, best regards from Santiago de Chile... ATT: Jaime....
Build video, please! I have a 98 Durango with a 44re that needs some work.
Input received. Thank you.
What is the difference between the 42RE and the 44RE? I have a 44RE in my Jeep and I was wondering if I can reuse the same parts you listes on the resouces.
And great job!! This video is amazing!!
The difference will come down to clutch capacity for certain drums. In other words, the number of friction clutches that will be used for a particular clutch drum.
42 may come with less clutches, and 44 may come with additional ones.
Be sure and order the correct kit for your vehicle.
The positive feedback is appreciated.
What always amazes me on this overdrive is that small thin wire is all that that is holding that humongous spring. You did not mention quite an important safety tip that the hub may not lift evenly and get caught up.
Also is it just me, or there is an aftermarket billet input shaft/drum?
Yes, they can get crooked during removal. Once again, be careful.
The aftermarket does make billet input shafts/drums for the 47RE/47RH/48RE.
Plz help need to knw I'm at 6 qrts atf+4 now just replaced filter and fluid break in point 1st flush have an 064-8 with 787 torque converter 14 bolt 5qrt pan and 4 spd tourqe flight O/D 2wd 2ND GEN HOW MANY MORE QUARTS DO I NEED OR WILL IT ALL HOLD max?

Esse câmbio é o mesmo da Dodge Dakota v8????
Good
Thanks.
Just wondering in the process of reinstalling the valve body but keep having issues with the parking rod on my 44re where does it go exactly keeps getting jammed or stuck in the overdrive assembly
The rod get's pushed into the Park Pawl, located in the rear of the extension housing (Overdrive Housing). The Park Pawl (housing) and Park Gear (rotating assembly) may be in a position where the Park Pawl can not physically move out of the way of the Park Rod, during assembly.
If I was dealing with this issue, I'd rotate the output shaft slowly while installing the rod. This will allow the Park Pawl to move.
I desperately need the rebuild video.
I have this unit in my Jeep, I'm curious if there is a way to modify they valve body to where manually selecting 2nd gear would force hold that gear..? I have deep axle gears and it would be nice to be able to force a 2nd gear shift
Are you talking about shifting to 2nd, and preventing an up-shift to 3rd gear? Or a down-shift to 1st gear? Or both?
@@SouthpawAutoworks Yes holding the gear. Sort of like a reverse manual valve body in a rock crawler. I think that might be the only way to do it.
I would like to see a build video too.
Input received. Thank you.
Hello! I have Dodge Ram 1500 4x4 2001 5.2 and have some problems with the transmission how i can know what transmission have my truck.
That vehicle should be equipped with the 46RH (also known as the A518).
The 46RH looks just like the 42/44RE...nearly identical, in a lot of ways. The 46RH uses bigger internal components, designed to handle more power.
The units are very similar in many ways. However, the transmission controls are quite different.
The "H" in the RH stands for hydraulic.
The "E" in RE stands for electronic.
I have a problem with the same transmission. when I put in reverse engine stop running. Can you please help me?
It sounds like the converter clutch is coming on, when it's not supposed to.
It could be number of things causing it.
A problem with the:
1). Converter.
2). Pump.
3). VB (valve-body).
4). Electrical.
5). Etc.
you are cool guys and i love what you do i have two cars with this transmission and i really want to get to know it closely i really want to make it more productive sport how to contact you for questions?
Two cars with this transmission....right on.
For the time being, this (UA-cam comments) is the only way to reach us.
Feel free to comment, and we will do our best to fire back, as time permits.
Please do a 42RH supplementary video

We would love to do a series on this transmission. Thank you for your input.
We're currently working our way through a full build series on a different transmission. It's the TH400 (GM Turbo 400). While there are many difference between the TH400 and the 44RE, there are also a lot of similarities, too.

Thanks for dropping us a line.
On every 518 I've done over the years, the plate that's on the overdrive sungear goes bad, in watching a few videos it seems no one checks it, you took it apart, now see if the round plate spins on the gear, if it doesn't it needs the plate ..
Right you are...they're always worn out. Thank you for your input.
We did happen to cover that topic in the inspection video.

Can I use a 2000 wj 42re transmission in my 96 zj with a 42re transmission
Your knowledge would be greatly appreciated
who sells the best snap ring pliers? thanks
Great question.
We use a number of different snap-ring pliers...from a number of different brands. Some are a bit pricey, and some are quite inexpensive.
We'll make a video on that topic...when time permits.
Here's the pliers used in this particular video: ebay.us/WbGFw5 (paid link)

Isn’t this the transmission that carries a death sentence if you mess with the spring with the improper tools and knowledge. I remember taking a dodge transmission apart and there was a spring inside of it that carried about 800 pounds of pressure I didn’t know what I was doing and that thing nearly took my hand off and could’ve struck my face and killed me
Yup, this be the one.
Dang... I believe it.
@@SouthpawAutoworks Yeah I just hope the DIYers understand the importance of how the spring comes apart even though the O-ring or snap ring has been removed you still need to exercise extreme caution just in case it tries to hang up as the pressure is being released in the Press Leaving a loaded missile on the bench. that’s what happened to me. I thought it was free and ready to come apart but it was hung up somehow I guess in one of the groves or something Lucky for me I had actually dropped it and Kapow. yeah literally spring and all passed right through the sheet metal roof decking and insulation leaving a hole the size of a softball in the roof. Do it yourselfers Please be careful out there messing with these Dodge transmissions.
talked about @ 16:53 and 44:00 minute marks - be safe
@@SouthpawAutoworks by the way I love the video one of the best I’ve ever seen as far as this assembly I think a lot of people want to see it overhauled there are some important key factors with this unit especially when it comes to setting up the clearances as Andy pointed out every time you post you inspire me to broaden my knowledge to other units right now I’m addicted to the 4L60E and have been for years it all started with the 700R4 and TH400/4L80 and TH350 and 350C General motor is junkie lol 😝 ha ha ha ha ha ha ha
So.. If that's basically a 904 trans, I could take that 383 out of my Giant Chrysler an put it in my 01Grand Cherokee ??😁
Yeah, a 904 with an overdrive section.
Loved the video. I was skeptical of trying to do the job myself (not a lot of disposable income these days so can’t afford to take it to be rebuilt) but with your videos and tips/tricks I’m feeling a lot more confident in it. Thanks a lot for the video.
Right on!
Wishing you all the best on your build.
Well, how'd it go? Did you attempt to r&r your tranny yourself?
