Since I can't decide what to do I'll post the question to all of you guys.

As youmay or may not know, my daily driver is the 1983 in my sig. Since I've had it tagged, I have been plagued with a tranny leak. Most, if not all, of the outside seals have been replaced. I am beginning to believe that there is an internal problem that is pushing the fluid out by the pan. The trans is the infamous 3-speed 200C.

My one friend at work has a trans from an 89 V6 Firebird with about 170K on it. It worked up to the point when the motor blew and was then pulled this past summer. They are doing the v6 to V8 thing so the V6 parts are at my disposal.

My question is: WHAT SHOULD I DO???

I can have the husband of another aquaintance take a look at it and fix the ol' 200C (he is a trans rebuilder for a Chevy dealership).

Or I could get the 700R4 off my friend and install it or have the trans guy put it in (had a bad experience putting a trans in my Aspen back in '97).

I kind of am torn between leaving it stock but realize the better gas mileage I could get with the 700R4.

After poking around a little more, I think the leak ids coming from the Torque converter and seeping past the pan gasket.

HELP!!!

 

I would get a 700R4. With a 3:08 first gear and .7 overdrive, its a much better investment. You will need a different crossmember, driveshaft and torque arm though.
