I swapped my 94 with a 97 trans I was told that the 97 used a pwm tcc and that was the only difference. is it possible that the harness is pinned differently than the harness for the 94?

I keep getting a code pwmtcc feedback.. any insght would be great thanks...

lets try this again.. thanks

 

To make that 97 work in your 94 your gonna need a pcm and wiring harness from a 95 to 97. I would just sell the 97 and buy a 94 to save the hassel.

 

Wait a minute. The 95 and 94 4L60E are interchangable. So im being told by Tranmission guys. Look over at the Drivetrain section. Just found this out myself. BUT the 97 TRanny you have WONT work unless you swap everything else. Sell it or trade for a 94 or 95

 

95 and 94 DO NOT INTERCHANGE dont try it. lol.
