We have not discussed the engine... the OE turbo V-6 will be used or ??
The converter is very heavy on a 4l80E unless you have a custom unit built. We've built several small 10 inch converters for the 4L80E. Billet converter front cover and stuff inside, very expensive
A friend of mine was an engineer on the 4L80E in the early days. They tried the tranny against the ZR-1 motor for the vettes. The heavy converter hurt the RPM acceleration of the engine too much I was told.
THe bands of the 4L80E... rear band is a copy of the T-400 , no adjustment to it.
The front band... if you are using the late wide band the matching longer servo pin must be used. No adjustment usually needed there
Yesterday is history.
