6l80e in 4th Gen
These new units have control modules INSIDE the transmission
which communicate with the pcm to determine shift characteristics.
They are not going to be "swap-able" any time soon.
40Ft/LBS
J/K Doesn't the '80' mean 800Ft/LBs in first gear?
So torque*1st gear ratio should be less than 800ft/lbs in order for the tranny to last...
