Anyone put the new 6L90 6 speed automatic transmission into a tri-five?
Its a 4l80 that they turned into a 6 speed. That's not really worth it for those gears ratios. The 700r is better than that.You proably already know this, but I didn't, TCI has an ad for a 6 speed automatic in the May 09 Car Craft. Low gear is only a 2.97 and OD is .75. It doesn't look as large as the factory 6 spd and it is rated to 850HP. Check their web site www.tciauto.com, they have the package priced at $6064.35 with paddle shifters, transmission control unit, cooler, and harness. Very interesting

I would like to see it setting in the frame rails? Any pictures.
Are you wating on GM harness.
Sort of. It'll be a while before I'm ready to start it, so that gives GMPP more time, so I'll hold off on buying Speartech's harness. If GMPP comes out with theirs, I'll buy it; if not, I'll have to give John at Speartech a call. Only thing is I've already spent money on the E67 ECU, and the harness for the LS376.
Did you check Speartech or even Mast Motorsports Mast has there own ECM as well. Yeah, and John wants $1500.
Most harness will be over $1000.
I am really wanting to do a 6l80 in mine, heck everything!
Congrats man! :congrats:
