alright so the cooler lines on a 99 have one thread in fitting (into trans) and one snap ring fitting (on the radiator side). I think earlier cars have a thread in fitting on both sides of the lines. I ended up having to buy new transmission cooler lines for the regal when I put an 02 trans in it, so that both ends are snap ring style. I think I paid 64 bucks total for the lines. gotta shop around dealerships for good prices. I got mine at Hoskins chevrolet. one of the best places... plus with new lines you can crank the line pressure and not worry...
there is a white GS at aurora with trans still in it. not separated from the motor so it should be ok still. either way it's $100 if you get it out yourself. the car had an interior fire, and halfway decent stock lim gaskets so my best bet is that trans is good and around 90k miles or less. pleanty of other cars there too that still have transmissions, some burned cars as well, which I am sure transmissions are still good in.
the passenger side axle needs to be changed IIRC when going to a 3.29 trans with an HD diff, but you already have the correct axle so you wouldn't need to change it.
james would know best about trans differences... as usual. I dont know if the 04's have an internal range switch or not...
I have a trans in the backyard that needs a rebuild...
fuck transmissions.
Dude, I hear that.
Thanks for all the 411. I need to re-read this entire thread when I get home and digest it all... then come up with a game plan.
