Anyone have a pin-out for the 4T65E-HD trans found in the 2000 GTP's? I am looking for the pin-out for both the connectors; the round one & the one by the shift lever... Nothing came up in the search, so I don't know if one exists or I am entering the wrong words??

Thanks for the help,
AL

Your range switch doesn't have two connectors?



I'm not sure this matches what your transmission uses



The smaller of the two connectors on the range switch





The range switch uses the connector between the two large ones, and the one to the upper right of middle for reverse. It's easy to figure out with a continuity tester. And yes the two large connectors are for the starter solenoid

Yes, my range switch has two connectors, sorry...

My round connector looks like 99% of the wires go to the PCM; I think there were 2 or 3 that did not have PCM pins on them. I will get there color/location tomorrow...

The other two connectors also look like the majority of the wires have PCM pins, but there were quite a few wires that did not have pins. Again, I will get there color/location in the morning...

Ok, so this is what I have so far...

On the large round connector:
I have two wires that do not have PCM pins on them
Black = ?
Pink = ?

The smaller 4-pin connector on the range switch:
Looks like all 4 of those wires go to the PCM

The larger 7-pin connector on the range switch:
Black = Ground
Green1 = ?
Orange = ?
Orange/blk = ?
Purple = Starter Solenoid, to the smallest of the three terminals
Green2 = C500 lt Green to pin R1
Yellow = C500 Large yellow to pin A4 or Large purple to pin E2
