I’ve been trying to find some more information on the part circled in the picture below. This 4T80E is from an unknown vehicle (the metal tag that I think is supposed to be bolted along with the valve cover is not there). So not sure if I’m out of luck or if there’s any other places that will have the transmissions identifying codes stamped on
I know that some components were internalized after a certain year including the neutral safety switch, and knowing that stamp info would help me know my final gear ratio!
When this transmission showed up, it came with no sensors or anything. We went to the junkyard to see what parts we might need. We found multiple cars with 4T80s. Here’s where the question comes in, some had the part circled in the picture below, some didn’t. It goes on the shift selector stalk, and has two wire connectors to it and what looks like a vacuum line?
One place I looked up said this was a neutral safety switch? But this seems entirely electronic? Some of the cars in the junkyard had this, others didn’t (and given the shifter cables were still on, we assumed they never had one).
If we are using a mechanical neutral safety switch in our gear selector, do we need this circled component? And if we do, any input into how it works would be appreciated. We do have the shop manual, but it hasn’t been great on details around this component us in on this part. If we don’t need it, it will make routing the exhaust much easier to do! I just assume we can tune out any warnings/interrupts it would be throwing to the ECU (likely going with Holley Terminator or MegaSquirt).
EDIT: took the img tags off the link. The box was appearing but showing broken in thread, however when I right-clicked and examine object, it was previewing right in the window. So guessing the forum doesn’t like PNG? If you click on the “broken” picture below it pops up correctly.
