Reverse light help

I've had this problem for a while now where my reverse lights won't come on when I throw it in to reverse. Is there a switch somewhere that went bad? Something on the shifter not picking up that it's in reverse? I can reverse no problem. Put in two new bulbs for each side didn't affect it.

There is a PARK/NEUTRAL POSITION SWITCH that controls the power to those lamps. This switch is located on the left side of the transmission housing. The two outer terminals of the switch connector control the power to the lights. You could probably test for continuity on these locations to verify the switch is bad or not.

Thanks, I was told by someone that I'd have to open the whole transmission to fix it, didn't think that was right

Yeah, that would be crazy. The switch is fairly simple to swap out if it's the cause. What engine do you have? I should have been more clear in my posting. Those posts were for the 42RE transmission common with the 4.0 motor. If you have the 545 transmission, then yeah, looks like yours is inside the valve body housing in the transmission. More work involved there.

If I am correct it is the TRS cam plate that the shift solenoid sits on. I just replaced mine with the updated solenoid and cam plate.

It really was not that bad. very messy and it took me a bit to do because i wanted to make sure I didn't screw anything up also since i had the valve body out I did the transgo shift upgrade.
