If you can rebuild a 1G AWD tranny to spec, and live in northen CA/bay area, can you rebuild my tranny? 2nd gear, as well as 3rd is grinding. I supply payment and all replacement parts. I'll also help drop the tranny out.
Or, if anyone knows a reasonably priced and good mechanic familiar with the 1G 4g63 tranny, if you could give me contact info, that would be much appreciated. (I don't want to hassel with shipping a tranny.)

Or, if anyone here knows a mitsubishi parts yard in northen CA that have 1G AWD trannies, can you supply me with a contact?

look on vfaq.com ... it has a step by step tranny rebuild that's very easy to do. If you can take the trans off the car and have time to spare then you can rebuild it as well.

Just dropping a transaxel case from beneath the engine bay is MUCH easier than completely rebuilding a transmission. In general, it's just removing components in the way of the tranny from being dropped.
Have YOU ever rebuilt an entire 1G tranny? I've read instructions over, and over and over again about the rebuild, and it is VERY complex. A machine press is needed to seat gears and bearings. There are shims, and micrometer spacings that need attention. There are numerous snap rings, shift forks, syncros, loose ball bearings, etc...etc, which all must be installed perfectly.
It's not a "plug and play" repair. Why do you think Sheperd or TRE, or RRE charge atleast $800.00 for a rebuild? It's not as easy as people think.
 
Do your self a favor and just send it to Shep for a basic rebuild. It may save you money now to just "try" and get it right but you will have to drop it and do it again I am sure. If it were as easy as some think they more people would build them.

Yep. You're probably right. I guess I'll bite the bullet and try to send it to shep.

I rebuilt my 2g tranny as a matter of fact ( awd as well ) ... it takes some time but once you realize what all the parts do it's very simple. The only remotely difficult thing is shiming the trans and pressing the gears on ... you CAN'T mess up the ball bearings or put the forks on wrong because it just won't go together then. I recommend you send it to shep as well though if you can afford the rebuild there.

I stand corrected. Also, you're probably one of the few who have rebuilt one.
 
I have as well. I'm not going to say that it's easy, but it's not as hard as one would think. You just have to be precise with everything and make sure you test it before you bolt it back up to the engine. It was a great experience and I plan to rebuild it every time I break it :thumb:
