4T60E rebuild, done!

[crash93ssei]

Long story short....

Trans died in my old '93, I told Nikki (current owner) that I would fix it for her. I found a guy that joined up on here that lives about two hours away, got ahold of him and said he had one, but he was going to go through it first to make sure it was good. That was three weeks ago, and I have been in contact with him several times and I was supposed to pick the trans up several times. One day I even drove down there, like we had agreed to, I got ten minutes from his house and he called and cancelled.... I was pissed. He said that he would get it done that day and bring it up to me, that was last Sunday. After a couple more chats, he was supposed to be at my house this morning at 7 AM and he was going to bring the trans and help me install it... of course, he didn't show. I also didn't expect him to show, so I decided to go outside at 7 AM and tear the trans apart myself.

I still have the old trans that I pulled out of the car two years ago from burnt clutches and a bad diff, I used parts out of that trans to repair this one.

Some may remember the clunking noise that I said was in the trans after I put it in... well, this was the source.
Bad, from the trans that just went out


Good, from the old trans


This is what turns the shaft that turns the differential. Now I know why it didn't move at all.




Good one from the donor trans


BAD plastic thrust washer


Better plastic thrust washer from donor trans, but it was ready to break, so I picked up a good one from the trans shop in town


All tore apart


The trans will be put back together tomorrow morning, and hopefully be back on the road before we leave for camping Saturday morning. It only took about a half hour to get it all tore apart, then another two hours sorting through parts and trying to get all the clutches back together and lined up right. The trans is mostly back together right now, just have to put the drive chain on and channel plate then change out the filter and good to go!

Wasn't that bad was it...LOL

Lookin' super great Ryan. Too bad the other guy couldn't work out, he seemed decent enough in the FS thread.

Whos says you need a sterile room to do auto trans' in?

Wanna do mine?

[JAmon]

You make it look so easy. I think you need to host another meet "real soon", and we'll tear into mine. I had it rebuilt, less than 2 years ago. It started leaking from the pan, and I accidently overfilled it. Needless to say I no longer have 1st or 4th gear. It has sat since March.

Bad deal for sure, but what can ya do? He does seem like a hell of a good guy on the phone, just not so much good on his word I guess.

I have rebuilt many GM rwd transmissions, but this is my first fwd trans, which is why I wanted to just find a good one in the first place, that didn't work out, so I said screw it and did it myself. As far as a sterile room? Well, that would be ideal, but lets face it, we can't have an ideal situation all the time. Every one I have done has been in a garage on a table with lots of clean rags. Just make sure everything is as clean as you can get it before putting it back together and all is good.

That sucks. :( I think we might be able to come up with something though!




EDIT....

Trans is done, and both it and the engine are now bolted to the engine cradle. It started to sprinkle / rain so I gave up for the day, time to take a shower and get headed to work. Pics tomorrow

Trans is in and works beautifully now! Took me from about 7 am till 5 pm to get the cradle bolted up and everything else finished, had to replace the oil pressure sending unit and a caliper, but it is back on the road now and Nikki is happy.

Awesome! Congrats. Too bad on getting that other trans but at least you were able to get it fixed!

Same deal on our '93 though. I'm starting to look for another transmission already. It hasn't gone out yet, but I've noticed the sounds it's making . Especially the last 80k or so of her 176k miles, from the way I know I drove it and how I suspect my brother drives it, the trans has definitely had a tough life.

[crash93ssei]

It is still working great, it shifts perfect with no chattering, hesitation, or anything.

William, is that trans making noise like the trans in this car did? Sounds like two hammers hitting each other when a slight rev is given in park or neutral?
