reverse light switch location

hi people i have a 92 4.3 s-10 and out of nowhere the reverse lights stopped working, though for whatever reason they choose to work once every few days. i replaced the bulbs so that is not a problem and i am thinking that either the reverse light switch is bad or the plug may be dirty or came off. does anyone know the location? i put the truck on the lift and unplugged the 2 wires on the drivers' side and plugged them back in which did nothing. i don't have a t-5 i have the 5speed that has an integrated bell housing. any help is appreciated

Re: reverse light switch location

there should be two sensors in the drivers side of your transmission, the rear one is for the speedometer and the front one is for your back up lights.

Re: reverse light switch location

by the way, does anyone know if i can just take the switch out of the trans as it sits or will it leak fluid/do i have to take the shifter out?

Re: reverse light switch location

well, i put the truck on the lift and put it in reverse and the light didn't come on, and i wiggled the connector and found that it wasn't the wire or the plug on it, but the actual switch itself had to be wiggled to get the lights to come on. i was going to unscrew the switch out of the trans but i don't have a chiltons or blowup of the trans assembly so i am not sure if the fluid level reaches that high or whether removing the switch itself requires the shifter being taken out of the top. i figure i would take a look at it to see if it just needed to be cleaned but i will most likely just pick up a new switch from a parts store, though they might have to order it. the only thing keeping me from that is the fact that it is my only transportation and i don't wanna render the truck useless by messing with the shifter and trans unless it just unscrews out and another can be screwed right back in. it's been a while since i have messed with a t-5 or tremec so i don't remember how the reverse light switch worked in them but i am assuming that the new venture wouldn't be too different....any ideas?

Re: reverse light switch location

Very similar problem... 97 sonoma 4.3 5spd...

Removed plug from switch.. Jumped the wires in the plug. LIGHTS WORK.

Replaced switch. No lights yet. TWO bad switches????

BTW, both switches will "make" off the truck. what ever is in the transmission pushing on that ball could be worn out... or I have two switches..

Re: reverse light switch location

MY neighbor has a lathe.... He chucked my new switch up in his lathe and milled 30 thousandths of an inch off the face of the nut portion of the switch. IT WORKS NOW.. thats about 1.3/32 of an inch further that it screws into the transmission....................... PROBLEM SOLVED..

Re: reverse light switch location

Everything checked out... Except the switch would not make when installed.

SO, my neighbor chucked one of my switches in his lathe and milled 30/1000ths off the face of the nut part of the switch so it would go into the transmission 1/32 inch further.. PROBLEM SOLVED.
