95 and 93 STS gearbox harnesses


Recommended Posts


Has anyone swapped an older (93) tranny to a 95 car and encountered the wiring harness problem?

93 gearbox has 2 plugs: 8pin and 6pin, while 95 has only one round plug with 14 pins.

I need to change the plugs without opening the tranny, so basically what i need is to know which wire connects to which one. Old-new.

Sounds like you are looking at two different trans that are used on Cadillacs.

There is a 4t60.....and then the 4t80 used for Northstars.
