I purchased a camaro off a guy a few years ago as a project and have put off doing anything to it while i saved up the money. I have finally got the money together to finish the car completely and want to swap out transmissions. The car is 1999 SS with a t76 turbo installed. The guy i bought it from switched the transmission out to a turbo 400. This is a great transmission for the track but I would like to drive it on the street and three gears just sucks. I am wanting to buy a 4l60e and have it professionally built for this high horsepower application. The problem is I have no idea where to even start. Are all 4l60e transmissions the same? A guy i know has one out of a 98 gmc sierra i was going to buy as a core but im not sure if its compatible. Anyone with any technical help would be great. Also if anybody has a core that will bolt up to an Ls1 they want to sell here in Michigan I would be interested.

 

All the bell housings are the same so yes, it will bolt up, but im not sure about the cross member.

 

alright sweet thanks for the help

 

To use that transmission you have 2 options.
A. Buy a new bellhousing, torque converter, shift mechanism, tail housing, and shifter cable.
B. Run the gm spacer and buy everything else mentioned besides the bellhousing.
