You'll be able to run that trans fine, if you don't go WOT at every light. Now, if you beat on your car no 4t6x trans can help you....

Spiral did one on his 93 bonnie. You'll need a custom chip burned for that engine, and the new gear ratio.

I put over 20,000km in my Fiero with the 3800SC and a 4T65E with no problems. I didn't use the HD version but that may be because its a light car. 4T65E HD tranny'* can easily be found at many wreckers varying from $500 to $1,200 in price depending on mileage. Only difference is in the differential and one axle shaft is a larger diameter. I wouldn't hesitate to swap a 3800SC series II into any GM vehicle. Dan

sounds like a lot of work...i was debating on doing it on my car if the engine ever went, and i think i will still go for it, but i shouldnt have to worry about that for a while ive go 97k miles on mine...but u guys r a lot of help

You know, it I didn't already have a project car, I would have been all over this. I still can't believe that nobody on here hasn't done it before (or said anything about it).
