Broke the Brat/How to fix a tranny

Took the Brat out wheelin yesterday, a little last run on 05. Played in the mud for a while, and started headin home. Got about half way there, and something locked up, I was gettin this awful grinding and clunking sound coming from under me. I'm thinking that it's prolly the T-case. Boy was I wrong. Found out a 92 Legacy can pull a 3000 pound Brat fairly well.

Got it into the shop today, and started taking stuff apart. Pulled the input shaft from the tranny to the T-case. Fired up the motor and put it in gear, same sound came from under me, crap, it's the tranny. Now come the interesting part. With the engineering of my lift, there is only two ways to take out the tranny, pull the motor, and then the tranny, or take off the body. I opted for the latter of the two. This presented me with a kewlness factor. I could tear into the tranny, without having to take it out! So I pull off the tail housing, and find my problem. The gears that drive the output for the rear of the tranny are gone! Luck be with me, I've got a 5spd torn apart in my bench. So I take off the transfere housing, and start fixin it. I've got some pics up in my gallery of the repair process. This also gives everyone a good look at my frame. You can see them here:

Grrrr..... Looks like it's back to the drawing board. Time to start from scratch once again. The friggin frame is tweaked!!I could only get 3 of the bolt holes to line up!!!!! AAARRRGGGG!!!!! And as thing would have it, I'm completely out of money.... grrr, looks like the Brat is going to go into storage for a while, a long while, I don't get back from Afganistan until mid 2007, and I leave in 3 months...

When I'm out muddin I usually end up up to the valve covers in water. Last tie I went out (before this one, where I broke the tranny) I had a problem with my vent line (all vents connect to a common) and ended up with water in all my gear oil. It's not a whole lot, but enough to turn it brown and milkshakey.

I just blew my third tranny. It makes a bad clunking in 4wd. I managed to drive it back home in 2wd, no clunking, but the gear shift gradually became harder to shift, so i drove mostly in sec or third. By the time i got home, i barely got it in first, parked it, then the next day, barely got it in neutral so i could roll the car. All the trannies are EA71 single range. The first two just broke the front diff, this one was something else. I'll gut it sometime to see what i broke. Gonna put an EA81 dual range in it now, coupled to my special JDM EA71 with EA81 style bellhousing and flywheel.
