from a control standpoint, there isn't much difference between the 60 and 80, the biggest two things i can come up with are gear ratios differ a bit, so slip calculated would be off without correction, and that the 80 only uses a single TCC related solenoid (PWM) while the 60 uses a PWM and discrete solenoid.
the 80 has the advantage of an input shaft speed sensor, so slip can be calculated better.
the main calibration difference would be the table used for determining what duty cycle to run the PCS at based on desired pressure and trans temp.
other than that, i can't think of much that would need changed. once the trans temp gets high enough, the line pressure is ran closed-loop to help prevent slippage, which is one of the advantages of a PCS equipped transmission.
