My plan is to find a part jeep and rebuild the transmission first and then put it in my jeep immediately so I dont have any down time. This way I wont be in a rush either and wont end up messing anything up. I would like to rebuild the engine too. My engine isnt bad, it just smokes a little. Not a big deal, but the more you mess with the jeeps the more meticulous you get about small things.

Don't be afrain of rebuilding the transmission or transfer case yourself.  While it certainly sounds complicated, it really is not.  There are several great guides (with lots of photos) on this forum and the 2A forum that walk you through step-by-step.  The hardest part of the rebuild is determining what parts are bad/worn without having new/good parts to compare them to.  In my opinion, if there is a question of good/bad on a part, get a new one and replace it while it is out.  (Only use NOS or used OEM parts)

Rebuilding my tranny/t-case was one of the most rewarding parts of my rebuild.  Plus, it will get you some major respect in hot rod circles.  You can be talking to a guy that has built a twin turbo 502 big block in an Impala and tell him you rebuilt your own motor and he may smile politely.  When you tell him you rebuilt your own tranny, his eyes bulge out and he'll look at you like your crazy. :o

Austin,
You wouldn't be the fist guy to get good at holding it in gear at just the right time.  Enjoy the darn thing.  When you're ready, just don't make the mistake I made. (Piece meal replacement on parts). I had this thing apart 5 or 6 times replacing one part at a time.  Not a good plan of attack. :-[

Thanks for that info Tim. I keep hearing about Brass Bushings. One of my customers told me he has some new bushings machined from a higher quality brass. Its nice to see how everything looks before you go in. I will probably rebuild the trans when it starts getting cold out.

Austin,
Popping out of 2nd gear is a pretty common affliction on the T-90 transmission.� The internet is awash with this issue.�

I just got done fighting this same fight.� It generally means you have some worn out parts in the transmission.� It could be one part, or a combination of a few different parts.

I fought through this issue in my current build thread.� If you want to know what I ended up doing, here is a link to the start of my troubles.� It goes for a couple pages, but I did end up fixing the transmission.

It starts here about half way down on page 14 and trickles through to about page 17...

Tim, while im thinking about it, I have another question. My 3a jumps out of second when I take my foot off the gas. Still drivable, just a pain when I want to use 2nd gear to go down a hill. Is there a simple fix that doesnt involve a trans overhaul?

It is recommended to use a sealer between the sleeve and the yoke.  I used Permatex 2.

You will also want to use Permatex 2 to seal the splines between the output shaft and the yoke.  This is also a leak point.

That doesnt look bad at all.  Do I have to use any sealer or gasket makerial on that sleve?

I�m with you Mark.� I put this off mainly because I had a hard time spending that kind of money on a little steel disc.� But it does solve the leak problem.� I've now installed a sleeve at all four positions on two different Willys.� �I should try to figure out how to invest in this company. :D

Here are a few photos of what to look for, and the process. Scroll down about 1/3 of the page.

That is a fairly common leak point.  If the seal surface on the yoke is grooved, you may need to add a speedi-sleeve to the yoke and replace the seal.

It looks like the oil is leaking on the front where the drive shaft connects.

That's great.  Congratulations.

Where on the differential are you losing the oil?  Front? Back? Bottom?  All?

Iv been driving it around all weekend. I put over 100 miles on it. Only broke down twice (two simple fixes)  first it just died after I filled the gas tank. Took a few minutes to figure out  but i determined that it was becuause the gas tank was not vented. Other other time my clutch went to the floor. That was because the linkage came out, so I replaced it with a nut and lock washer. The only other problem I have is my rear axle leaks oil like a sive. Not a big problem while in driving, but when I stop I have to smell that gear oil cooking on my exhaust. Im going to try to find a kit and rebuild next weekend.
