Mechanic noticed this plug hanging out of place. It runs along side of my 700r4 transmission. It's a white plug. He says the end of it is broken and won't fit into the transmission plug anymore. He mentioned he thought it was a sensor or something for the locking torque converter?

What is this plug for? He taped up the end of the plug because it was shorting out against the trans. oil pan and was shorting out 3 fuses instantly.

He mentioned that it MAY not be needed and may have been unplugged on purpose when my Shift kit was installed in my 700r4 years ago.

Any thoughts? If this for the torque converter? IS it needed to be plugged in even if I have a shift kit or something?

Thanks

 

Whether a Shift kit was installed or not, it is the plug to lockup the torque converter. Get it fixed soon.

 

What does it do? What if it's not fixed? Any damage being done? NO idea how long it's been disconnected for..

 

It lets you lockup the torque converter clutch, which lowers temperature and rpm, and gets better gas mileage.

 

I'd get that fixed. You're not taking advantage of your 700R4 with that broken and you're generating a lot of excess heat in the process. A lot of miles like that can lead to a premature tranny rebuild if it's not dealt with.
