My 07 Tahoe reverse lights stays on even after I turn it off

2nd and 4th gear band is not applying. Possibly worn out. It comes on in 2nd and Overdrive. If this is the case, transmission will have to be overhauled.

It sounds to me like your gearbox is knackered, but just to be sure get underneath & check all the linkages, get yourself a workshop manual as linkages are easy to fit even for a novice, solenoids are relatively inexpensive so if you don't feel like doing this yourself then try this route first.

Yes it is true. I would call a local independent shop and see if you could get a used one installed. This would cost about half the price.

WERE YOU in auto 4wd or 4hi? sometimes vehicles will pop out of 4wd in reverse the auto mode detects slip going forward not backwards so if in auto tes it will have problems in reverse.

the fuse for the reverse lights is located on the underhood fuse block. Look for the fuselabel VEH Backup and it's 10amps. If the ignition is switched off, transm in Park, and the reverse lights still on, try removing this fuse. The reverse lights shoud be off, which means the wiring from the fuseblock going to the reverse lamps is not the fault. If the lights stayed on after removing the fuse, then you have two possible culprits. The underhood fuseblock may be shorted, or a BCM (Body Control Module) that is malfunctioning. This is assuming that the wirings going to these components are normally sound. This requires thorough testing procedures.. goodluck and have a nice day. : )

Brake Light Switch REMOVAL & INSTALLATION

1. Disconnect the negative battery cable.
2. Disable the SIR system (if equipped).
3. Remove the clip (R/V Series) or unclip the switch (C/K Series) and unplug the electrical connector from the brake light switch.
4. Remove the switch.
5. Installation is the reverse of removal.

your going to have to take it back to the desler to have the TPMS unit reprogrammed.

I have an '03 Chevy Tahoe and I had a similar problem. I discovered that there is a bare copper striking plate or tab that the medal emergency parking brake pedal touches when the emergency brake is set. It turns on the idiot brake light in the dash. It had broken off and the light stayed on all the time with the say issue of chiming whenever the vehicle is in motion. You or the dealership must replace that striker plate to fix the problem.

The reverse light switch is screwed into the transmission,and there are no adjustments.
