I have a early one piece case 4L60E Tag 3TAD(1993 4.3L truck). My research indicates that this tag is a non PWM transmission
It has a PWM pump and the valve body has a PWM solenoid for the torque converter circuit.
I have no knowledge of the history or who put it together.
Are these parts even compatible?
If so are there modifications needed to allow the torque converter lock up to function in "on /off" mode with a 12 pin harness plug computer?
As an aside....when did GM start using pulse width modulation for the 4L60 torque converter clutch apply?
Thanks to any responses in advance.
