Dude! You RULE! Please keep us all posted on your progress. My rebuild will have to wait at least a few months. But I'm stoked that all these resources are here for when I do tackle it. Thanks for sharing all this stuff.

Have any of you made any progress with your transmissions? I'm getting ready to start this and would like advice

Thanx

Yes, mine's in the basement on the bench in pieces. Advice, huh? Print the PDF instructions, even though it's like 44 pages. Make sure you have a bearing separator, and probably a press. I have two nice pullers that I may be able to make work instead of a press. Time will tell as I'm waiting on the separator from an eBay seller. An impact will be a great benefit. Drain as much oil out as you can before you start cracking the bolts loose to take the case apart. If you deal with Jon at TRE he'll tell you to take the tranny apart before you order parts. You'll need snap ring pliers. That's all I can think of at the moment. Let me know if you have specific questions and I'll try to answere them.

Hey Shawn,

You don't by chance have a similar manual for the transfer case do you?

Thanx

Check this out: I found another spot where the shift linkage develops play. It's in the lever that moves the control shaft in and out of the case. There are two metal (maybe aluminum) bushings that are pressed into the lever that had some play, and a nylon (plastic) block that has developed some slop over the last 11 years. I just got done machining some brass replacement bushings that fit tighter. No play at all now. I won't know how well it worked 'til I get the tranny rebuilt and in the car. Here's a photo of the lever and the old and new parts:

Dave, that's pretty sweet. I just replaced those bushings with new factory ones, and it's still not perfect. Seriously, make a bunch of those bushings, setup a simple ordering web page that takes paypal, and you're good to go. The shifter assembly could use 'em too.

I'll order the first set!

The FSM also has a rebuild section for the transfer case, too. But, I don't have it electronically.

You guys could order the $35 Backup manual CD from various vendors. That is a copy of the FSM, right?

While you're in there, pop the $ for the evo shift forks..they make the shifts feel way better. much more solid because you don't have the aluminum flexing..I'd go with the RRE forks if you have the extra cash. I rebuilt mine with new aluminum forks, only to have the tranny out 3 weeks later replacing them again with steel..bent one on the first race after the rebuild, and it was brand new.

I've heard mixed reviews about the EVO forks. Yeah, they're stronger but not necessarily perfect. Some have complained of the pads on the end of the forks wearing out too fast, or just falling off. I went with OEM aluminum.

TRE's EVO forks now have bronze wear pads that are held on by machine screws and silver solder. Jon seems to think they've worked all the kinks out, and highly recommended them. I think I'm going to try them.

Yeah, the EVO shift forks are just one of the upgrades that will be going in. Jon's got my center diff right now and will be converting it to a 4-spider gear unit. When he sends it back, it will be accompanied by all the other goodies.

Howard: I'll kick it around. It's pretty time intensive.

Yesss! FedEx just picked up my transmission, and its on its way to TRE. I'm getting the 4-spider diff too, the EVO forks, heavy duty synchros on 1,3,and 4, and the dual-sychro 2nd gear (of course). If there's any money left in the bank, I may get the higher 5th gear ratio. Anyone have any feedback on the 10% vs 25% change?

I finally got a chance to crack open the transmission last night:



Removing viscous coupling unit


View of ball in the center diff's rear shaft. Don't lose this! (I used compressed air to pop it out, then it fell inside the case, but I found it later. )


View of transmission with 'trans case adapter' removed.


Transmission case removed. View of input and intermediate shafts and front diff.


Close up of front diff.


Close up of center diff.

Gear selection assembly.


Close up of input and intermediate shafts. 1st/2nd gear on the left, 3rd/4th on the right.




That's all for now. Next is to start doing the RnR on the gears and synchros.

Btw, does anyone have a suggestion to give the trans case pieces a good cleaning to look like new? I scrubbed and scrubbed and what you see is the best I can do. That's caked on old coolant/oil mix.

Damn keep the pictures coming! Looks great so far. As for cleaning, maybe send it out when fully disassembled? I dunno...

Hmm.. Once clean, I wonder if powder coating is a good idea. Any recommendations?

But yeah, I can get the best cleaning done with all the case pieces bare. A friend has a sandblaster but I'm not sure that's a great idea.

Yeah, I dunno about the sandblaster thing. Sure would suck to have any sand left in the case after it's all back together. I think I'll just scrub the case pieces with Simple Green and water and leave it at that. As for powdercoating, anything you do is gonna get scratched up when you go to put the tranny back in. I'm just gonna leave mine.

The trans is disassembled and hot tanked the same day. - Taken from team rip
Also I would put in md738053 it is a rainbow shaped screen. They have a spot to put it in our cars but did not put them in till 95. And mb001293 it's the drain plug for the transfer case which is the same as the trans only magnetic. md000312 is the gasket for the plug it is a 18mm plug I think mitsu wanted alot for these gaskets.

Tell me more about hot tanking. Where would I go for that? What exactly is the process?

This isn't in regard to hot tanking, but keep in mind the case is aluminum and some solvents will damage it.

Tonight I started pulling gears off the shafts. I find that my Harbor Freight bearing separator really sucks. I think it's made of recycled mufflers.

Here's the progress and the damage:

This is a hell of a magnetic field around the trash magnet! :eek:


1st/2nd gearset removed from intermediate shaft.


This is your synchro. This is your synchro on drugs. And yes, 2nd gear grinded a lot. Notice the decorative brass shard on the gear.


This is the Harbor Freight 12t press.


Here's the problem:


The bearing separator has a pretty dull clamping edge so I sharpened it with my dremel. The metal was very soft, which is what causes the problem. The bearing busts off the rollers, leaving what you see here, and taking some chips off with it (at about 50mph). So I tried clamping the bearing separator around it and tried again, but this only continued to chip the edges.

So I think I need a better method or tool. What can someone suggest?

With the hot tanks we have at my work, you simply place the parts in it and set the timer. Then it sprays it with extremly hot water. You can add cleaners if you want. Usually if you run it with water for a few hours, it comes out pretty good.

I'm pretty sure you're supposed to put the separator on the back side of the bearing. Will it not fit? I'm still waiting on my separator to be delivered so I can begin pressing the gears/bearings off the shafts. I don't think my parts from TRE will be here in less than another week, so I'm not really in a big hurry.
