Mustang Transmission DESTROYED (5R55S Teardown, No Drive or Reverse)
Вставка
- Опубліковано 26 сер 2024
- Mustang GT 5R55S automatic transmission would not go in drive or reverse, but would drive while in 1-3. I started tearing down the transmission until I found the problem. I go over all the steps and make a homemade transmission pump puller in the process. Is it worth saving? Where do I go from here?

Thanks. I'm an old shade-tree mechanic from the 1970's, and I learned more about transmissions. I turned 69 years old one month ago, but I'm still learning.
I'm glad I could help. The pursuit of knowledge is a lifelong endeavor.
That's the best video so far as explaining step by step....Kool, great job
Thanks man I try. I'm still trying to figure out how I want to do my channel, so I figured I'd start by doing videos That I'd like to see. I hate it when people aren't very descriptive and miss out on the little details.
That's the way to do it. If there are videos you want to see, it's certain there are people that want to see the same videos. Plus, it adds personalization to your channel, which helps your identity. 😊
@ericp7496 Anytime I need to do something and I can't find a good video, that's a perfect opportunity to share what I've learned for the next guy.
I been watching tons of videos on this transmission. Overdrive gears are a big problem. My Sun and Planets were completely stripped on overdrive so I had lost 2nd, 4th, and 5th.
I was told to order the Superior Shift Kit because it has you drill holes to supply more fluid to the overdrive section. Also, has a modified Flow Control Valve for the pump to prevent the valve from being stuck open. Was told that makes the transmission stop from working altogether if it gets stuck open.
To be honest, if the sprag was busted like that the overdrive band might be worn. I'd recommend getting at least a gasket and seal rebuild kit. If the clutches don't seem worn and the clearances are in spec, you shouldn't need clutches.
Also check the servo bores to see if there's any play in them. Some tranny experts resleeve them regardless. I took my case to the transmission shop to have them resleeve the servos because that tool kit is expensive. However, seeing your engineering skills you might be able to make your own tool for it.
Lastly I been told to check the rubber molding on the servo pistons. They tend to get hard and flake overtime if your tranny overheats. BTW, the shift kit also solves the overheating issue because it updates the internal thermostat so that it keeps sending fluid to the radiator.
Sorry for the long comment. I been doing months of research and asking questions 😅. Great to see other transmission DIY enthusiasts. Great job 👍!
I will definitely look into the kit. I noticed the seals on the servos didn't look the greatest but they weren't leaking, will probably replace. Thanks for the info because I was unsure of which direction I wanted to go in.
Thank you bro for sharing that, i have exact same issue with my mazda b4000 and i think some mustang have the same automatic transmission. I dont like to admit it but look like i have to pull it out
It's never a fun job and can easily take 2-3x longer than it should. I know the mazda is a smaller truck, but hopefully the Trans tunnels has plenty of room. The mustangs are a pain to get the top bellhousing bolts.
It was a good video man I listen to every single detail and it’s almost midnight for me keep up the good work
I appreciate it man. I tried to cover everything.
Gotta love garage ingenuity when you're in a pinch.
I'm just glad it worked. I didn't want to wait on that puller.
smart bro.. i like the diy pump puller idea.. fast to make, and saves you about $100..
I tossed it in the toolbox in case I need it again
I read this as “No drive or remorse”
That too 😂
Good job bubba. Great explanations on everything.
Not sure if I want to rebuild it or do a manual swap. Finding info on tolerances and parts numbers can be a problem.
@@octanedrivendream What about remanufactured? Are they a good buy? If mine ever fails that's probably the route I'll go. Too lazy to shift.....LOL
good video. I just got a 2000 explorer with the same problem.
Did you get the problem fixed? If not, prepare and take a weekend. Make sure you get a reseal kit and check the bands.
I just bought a 2008 v6 mustang, and guess what. Yonight it decided to do the no drive or reverse. I had to drive it home using 1,2,3. Not good.
So, did you decide on doing a complete rebuild, just replacing the skrag, or manual swap? I didnt see any more videos about it.
Thank you. This doesn't look like a hard(ish) thing to do. Guess Im going to drop transmission tomorrow and start pulling it apart.
I just replaced the sprag, overdrive band, and pump reseal kit. Been busy, so I haven't posted in awhile.
Thanks for the video and explanation.
I try to touch on everything I can think of 👍
My 2009 45th anniversary has this transmission. I've kept the trans fluid and filter changed regularly the life of the car, and at 176K, she's still running like new.
I bought this wrecked. Most people don't keep up on regular maintenance.
@@octanedrivendream That's true. If people could only realize that oil is cheaper than a rebuild.....
@@FreeSpeechisMyRight10 Way cheaper. So many people use and abuse their cars.
I have a 2006 Mustang GT I bought new and has been kept in excellent condition. Back in 2017 I started having intermittent shift flares in 2-3 whereby the car would suddenly act like it was in neutral. The problem became more frequent and in 2020 I replaced the solenoid pack and the valve body and I thought it was fixed but less than 1000 miles later the transmission quit altogether with no reverse or drive and it could only be moved in 3rd. I got a remanufactured transmission from Ford in 2021. It supposedly addresses all of the weak points of this transmission. There have been many failures of these transmissions. My car had less than 100,000 miles when this failure happened. With the new transmission now it runs like a champ. I have no idea what failed in the original transmission. It was sent back to the company that does the remanufacturing for Ford but I was told there was no way to investigate the failure. It would have been nice to know as I spent a lot or money on it. Any idea what might have happened as it was not the valve body or the solenoid pack as both had been replaced with brand new Ford parts?
@@newfie-dean5803 I'm sorry to hear this happened. I do know there were a lot of problems in 2005-2007 models, and that a lot of stuff was ironed out in 2008-2009. That may attest to the fact I haven't had any issues. I wanted the first generation, because the 2010 and later models are so damned ugly.....
Good job
Thank you 👍
I do NOT advise it, but I have picked the entire transmission up (a 5r55s) and lightly bumped the face of the bellhousing onto a piece of cardboard and dropped the pump out with a few other gut pieces, but this can damage something. it does work in a pinch especially if you're as crazy as I am :D
I also recommend replacing the input shaft before installing the pump as i've messed up the splines on my new OD planet and had to get another one
If my homemade puller didn't work, I would have spent the cash and waited. I want to do the least amount of damage possible 😂 Thanks for the tip though, I'll keep it in mind when I reinstall.
I see your missing brass thrust washers on the OD planetary gears. Available form Sonnax 46580A-W. DYI rebuild videos available.
Holy shit man good lookin! Good thing it's tore down. I just went and looked and one of the gears is missing one of the outer ones. They also look different then the ones you linked. They are missing a side like a c clip, or are they not supposed to be that way?
This is gonna be my first any tips man?
Complete lemon transmission thanks Fix Or Repair Daily
I just pulled my transmission out for the same problem and I don't know whether to repair, replace, or manual swap lol
I know the feeling. For now, I purchased the sprag, a need band, and a pump seal kit. It's was around $60 for those things vs $300+ for a rebuild kit. Now it can drive until I come across a capable manual Trans for a decent price.
I have a similar probut.My case is the drive.The reverse is ok and I don't know what to do
15:42 does anyone know the name of the part inside the center of the assembly ? It’s the “W” shaped washer.
I'm not sure what you're talking about. The wavy bronze piece in the middle of the shaft? If so, I'm not positive but I think it's an oil control ring for the planetary gears.
I have the same problem but a Little different, with 1,2,3 Gear manual work good, with drive or reverse if you rev the engine It want to go but slips and move very very few. What do you think?
That's exactly what mines was doing. It would drive in 1,2,3 but not in drive or reverse. You probably have the same problem. When the Trans gets hot, it makes the cage of that bearing brittle and it breaks.
Typical 5r55s overdrive sprag torn up
You order a rebuild kit?
Not yet, trying to decide what route I wanna go. I'll probably order the parts separately because it's cheaper. Not sure if the Clutches and bands need replaced, or if that's exceptable wear.
@@octanedrivendream Watch a few rebuilds and then you'll know what to do. Good luck.
@@octanedrivendream always replace the bands no matter the wear. Unless they were JUST put in.
@diegom.9762 I was on the fence since I eventually want to do a manual swap. Just want it driving for now.
@@octanedrivendream 👍 yessir. I always just hot rod it anyways (saw dust and trans fluid in my 93 foxbody lx trans )
