GRANDFURY Posted December 31, 2003 Report Share Posted December 31, 2003 Hey guy in mis spring or towards the end of spring i'm planning to do a engine and tranny swap. I was thinking of just going with a 3.1 because they are cheap and easy to find. But what tranny is the better one the electric auto or the vaccuumm auto? I can't see myself doing a manual swap altough it would be nice but they are hard to find so wich is the better? What else will I have to change? Oh yeah my car is 1989 GP LE with 2.8 auto. Thanx guys. 8) Oh yeah anyone ever have a shop put in a tranny? If so wats the cost roughly. Thanx 8) Quote Link to comment Share on other sites More sharing options...
PaPaPooh Posted December 31, 2003 Report Share Posted December 31, 2003 non electric would be easiest because then you can use your ecm you have back in kc at the shop i worked at we charged 500 for a swap we didn't do just a install you can also use your 4t60 thats in there now if it is in working order good luck Quote Link to comment Share on other sites More sharing options...
patgizz Posted December 31, 2003 Report Share Posted December 31, 2003 i would stay with the 4t60 thats in there if it works, or another 4t60. also you can use your existing harness and ecm and just get a prom from a 3.1 car up to 92. i would shy away from the 4t60-e because #1 i have both and would rather diagnose a mechanical problem than a solenoid failure, and #2 swapping the E trans would require a new engine harness Quote Link to comment Share on other sites More sharing options...

Flyby736 Posted January 2, 2004 Report Share Posted January 2, 2004 series 1=4t60 series 2=4t65e Quote Link to comment Share on other sites More sharing options...
GRANDFURY Posted January 2, 2004 Author Report Share Posted January 2, 2004 Sweet so my stock tranny will work with a series one 3.8. Cool I just found one on a local yards website for 350 bucks, 60 buck for the computer, what else would I need? Axles? I know i will need all altenator and power steering crap but what else. They don't have any 3.1's so thats why i'm leaning toward this. The 3.8 is reliable right? Quote Link to comment Share on other sites More sharing options...
