Pin location for vehicle speed buffer
1992 CHEVROLET SUBURBAN
Brown and dark blue wire on a Delphi ECM #16147060? Truck not shifting w/o those wires. Transmission was transplanted from a donor and for some reason they are not there. Help!
have the same problem?

Truck will shift without those wires. The governor regulates the shifting in this trans.
Did you take the sensor from your trans and install it on the donor? Are they the same trans?

I believe it needs the vehicle speed buffer to reference vehicle speed. Swapped in a 4L80e transmission and the harness. Tranny goes into limp mode.
