Where is fuse located

depends on the make, model & year of the vehicle.

Which transmission ?
Automatic Transaxle - 4T45-E Automatic Transaxle - 4T65-E Automatic Transmission - 6T70/6T75

Its on the transmission housing.

Yes...there are fuses for virtually everything. That is for fire prevention. However, you don't say what make/mode/year/engine/transmission your vehicle has so additional info is difficult. I will say that the reverse lights generally do not have a DEDICATED fuse, so if a fuse was the problem, something else would also not be working. Reverse light problems are usually due to one of two things - as the lights are in the rear of the vehicle they are rarely checked for operation. They could simply be burned out, first one, then later the other. More likely, however is the backup light switch that activates them. On automatic transmission vehicles, the switch is usually located in, on, or near the shift linkage. On manual transmission vehicles, the switch is usually located somewhere on the side of the transmission housing.

It will be located with the rest of the fuses. Fuse blocks can be in more than one location so check manual for all locations. Manual should tell you which fuse is for the transmission.

Replace the transmission range switch for starters, if that doesn't correct the problem you have have a shorted shift solenoid on the valve body inside the transmission.

If the fuse is good and the reverse lights are good, I would suspect your problem will be the reverse light switch itself. I believe yours is located on the side of the transmission where your linkage connects, if you have an automatic transmission.
If you have a manual transmission , you'll probably have to contact the local automotive parts store and ask them to tell you where it's located.

There is an under-hood fuse box that houses several relays and fuses. The box is located under the hood near the battery. It has a cover over it, but isn't very big -- maybe 3" by 8". The ERLS fuse covers the automatic transmission (as well as the backup lights, canister purge valve, canister vent solenoid, EGR valve, ABS, variable-effort power steering, and AC compressor). The fuse is a 20A mini-fuse. It should be yellow.

hello, the back up lights are usually on the same fuse as the tail lights so if they are working it's not a fuse, if the tail lights are not working replace the tail fuse. Otherwise the problem is most the backup light switch, on the manual transmission it's a separate switch located on the transmission on an automatic it is incorporated into the neutral start switch also located on the transmission but on the shaft where the shift selector attaches.

hi no codes registering try looking at the shift soleniods relays and fuses its just a changing problem it drives ok otherwise paul
