The only hands on experience I had with transmissions bofore tearing into my E4OD, was replacing the overdrive gear in my sister's ranger. Aside from that, I just kind of winged it. Just about all of my info came off the web, I didn't even get a manual (but really probably should have). The advantage I had was that I still had the C6 in my truck, so I could take my time and make sure everything fit right without any extra parts. In the end my biggest mistake was getting a big block tranny instead of a diesel, now I have to get a proper case and go through this all over again --oh well.

There are some special tools that will be needed but since they are expencive (but very simple), I made my own. There are alot of pressure and clearance checks that should be made along the way, all of which (and other specs) should be included in an overhaul manual. Something I notced while reasembling mine, is that most (but not all!) of the hard parts cannot installed incorrectly, unless of corse they are forced. Get a good manual and read though it a few (dozen) times, then deside wether or not to go through with it or not.

BTW, you should have seen my pan when I first opened it, went through a few rags that day...

It turns out that the direct clutch was slipping and all the friction material got pumped through the trans, along with a lot steel filings. The direct clutch piston itself was partially melted (had to be replaced). It also took some time to clean out the valve body too.

One other thing is to make sure that you have a LOT of clean work space, there's a whole lot of guts in there.

 

david85 that sounds like me when i rebuilt mine there was about 1/2inch of sludge in the pan from burnt clutch plates. the forward clutch pack all the frictions and steels welded themselves together in one gig chunk. it was a mess needless to say, and i did the same thing you did i bought a c6 trans off a big block 351m to put in it to be told that it wouldnt work so i took all the parts out of it and built one trans out of both with a new rebuild kit and tc. its still pulling strong a year later (knock on wood).

 

j tate, all I can say is WOW! Sounds to me like that old clutch pack belongs up on the wall somewhere! In my case, the frictions and plates were still seperate, but it was getting hard to tell them apart. Oddly enough, everything else in the tranny was like new.

As for the case...I can't help but laugh, it looks like we ended up in the same boat. Who needs transmission shops anyway .

Glad things worked out for you though, I hope to have mine in by summer

 

i hear you on that i try not to take any of my vehicle to anybody to have them worked on. thank you and i hope everything goes good for your to.

 

We are a smaller isolated comunity on the B.C. coast, so the only place in town that does automatic trannys has a good rep. Called the guy today, told him, my story, he sayes yah, sounds like the TC, he does them all the time. He commented that hopefully the tranny has a 95 type pump as that made quite a differance, and that since my tranny has been in a shop before its hopefully been redone. Ordered a new double disc RV TC and will just change that out, as well as do a pressure check. At least they guy sounded like he knew what he was talking about, not like some of the stealership threads I've been reading, LOL. Also he recommended that the FILP at idle be set at at least 1.2v as it is better on the tranny life!!

 

I'm actually in campbell river, and I'm not even sure if we have a shop in town that does transmissions (except of course the stealerships). I ended up getting my TC from island torque converters in victoria. Since I had business in the south end of nanaimo, I figured whats another three hours. Dropped off my core at the same time.

I'm glad to hear that he mentioned the newer pumps, which tells me that he probably does know what he's talking about. If he knows about the updated pumps, than he'll probably know about the OD snap ring steel carriers, boost valve(s) etc.

FWI, if you ever want a second opinion, there is a transmission service group in victoria (ITC is a member). Many of these shops have been in the business for many years, and they don't seem to mind answering questions via e-mail or even over the phone. They helped me with some of my dilemas.
