What about the 2008 newer body Chevy Silverado the tcm plug is totally different? What’s pin #s do pin into that year of truck for the iss wire?
Wiring mods... Remove K(orange), V(light blue), S(white), T(tan/black) and U(brown) wires from transmission connecter. Move U(brown) wire to the S location. Front Input Speed Sensor (ISS) is made by using the orange and light blue wires. Add a VSS connector, connect orange to terminal A and light blue to terminal B. Move the low signal wire from pin 45 to location 26 in the TCM harness. Install the front Input Speed Sensor wiring connection Install the shift selector switch on the driver side you removed from the 60. The factory speed sensor can plug back into the 80e tailshaft sensor PCM/TCM... Conversion is finished, had to get a 2008 Chevrolet Express 4.8L/4L80e van C2500 TCM tune to get the transmission to shift correctly. There was nothing special done to make the TCM work in the Silverado, just swap them out. The TCM was loaded with a factory tune for an 80e transmission. Type: Chevy Express (V8) 2008 VIN: 1GCGG25C481106014 TCM... Segment 1: 24239927 Segment 2: 24235887 Segment 3: 24251658 Segment 4: 24235883 Without the 80e TCM tune there was no speedo output to the PCM and the tune would not enrichen the fueling when accelerating.

Sorry it won’t let me reply to the original message for some reason. But I already have my 45 pin moved the 26 on the TCM pin side I’m just not familiar with this year with the V. U. And S. coding on the plug? |
You can't reply to it because I locked the thread. The person whom started that thread has not not been on since 2013. The plug orientation and pin location was on the very first page.
