No Reverse Lights

Well my reverse lights were not working so I thought maybe I had the socket problem that is common. I purchased an aftermarket set of tail lights assembly's and just installed them but I still have no revers lights. The bulbs checked out fine.

I think I have read on here somewhere about a solenoid or possible neutral safety switch that can cause the reverse lights not to work. Any direction would be great.

I'm on moblie so can't see your jeep details.
If I remember correctly the 4.0 has reverse switch at gear shift lever but the 4.7 the switch is part of the transmission

42re switch is on the drivers side of the transmission body right behind the linkage and cooler lines. It's a 3 wire plug. The 45/545rfe has in inside the trans up above the valve body if I'm not mistaken. It needs a pan and fluid drop either way.

Sent from inside my 4.0.

I've made a thread on this and got no reply, did a search, still nothing. My reverse lights work about a third of the time. Not sure what causes it.

This is what I was remembering. So, I assume the "switch" that needs to be replaced is the Transmission Range Sensor (TRS) This is big bucks according to this post:

http://www.jeepforum.com/forum/f310/...tions-1249046/

Does anyone know if there is a wire coming out of the transmission that I could test to make sure I don't just have a problem in the wiring between the transmission and reverse light socket?

Update:

Tested the plug at the trailer hitch and I am not getting a reverse light there either.

I talked to my mechanic and he seems to think there is a Neutrals Safety Switch on the outside of the transmission. I called a parts store and they have one for $12.99. Gonna pick one of those up tonight and try that.

Any luck? It seems that all of these threads end without any resolution posted.

My wife's '04 Laredo 4.7 has the same reverse light issues.

I haven't tried the Neutral Safety Switch yet. I have lights on the back of my roof rack that I use, so its not urgent for me to fix my reverse lights. I will post up results if I can get around to actually doing it.

Last thread I followed found the reverse switch was in the transmission for the 4.7
Have a look in your manual.
I think (not sure ) that the reverse switch is at gear leaver for 4.0

That's what everyone seems to think but no one ever finishes these treads with results. Since the neutral safety switch is a $13 part and my mechanic thought it might work, I am willing to give it a try.

I had the same issue, check the connector on the transmission. Mine was not completely latched. Popped it in and no problem since.

Good suggestion, I will take a look at this tonight.

I pulled the wire connector off and reconnected it with no luck. There is not a Neutral Safety Switch on the 45/545. I only see the speed input and speed output sensors. For now I am assuming it is the solenoid in the transmission. I have gotten use to my "manual" reverse lights, so I think I am just going to run that setup for now. I went ahead and tapped my roof rack lights into my reverse lights, so I have plenty of light back there now!

Will the manual reverse lights pass inspection?
