4t60e on a 6.5?
 

I want to make a RWD setup with this combo, is it possible? will it even fit? exhaust manifolds etc. also what would it take to make it work? is it worth it? any and all ideas, comments are welcome

ok, so after a brief review, I don't want to muck around with the electronically controlled trannies, just a nice 4t60 HD build should be good. The article for the grand prix these came out of reads like this:
1989

A host of changes upgraded the Grand Prix for 1989. Air conditioning was standard, and the 2.8 L was replaced by GM's new 3.1 L MPFI V6 that produced 140 hp (100 kW) mid-way through the model year. For 1989, the 3.1 L was only mated to a four-speed automatic transmission, while the remaining 2.8 was mated to either manual or automatic transmissions. A new trim level was offered for 1989, a limited-edition turbo coupe that featured an ASC/McLaren turbocharged version of GM's 3.1 L V6 (Only 2000 were produced). Output was 205 hp (153 kW), 65 more than last year. A four-speed automatic was the only transmission offered. The coupe was an SE model with body work such as hood louvers and extra body cladding(which will be the most controversial design element in the years to come). The interior featured more equipment, and only seated four, in contrast to the LE's five seats. The full analog gauges would become the 1990-93 sport cluster, and the basis for the new instrument cluster to replace the digital cluster for 1990.
only 205 HP?? what a joke the torque these things put out will eat that tranny like yo momma eating a bag o chips.:td:
I don't have much choice in terms of bolt on transmissions for GM though so it looks like I'll have to custom build one for this purpose.
