Need to know what trouble code 55 is on the 1993 jeep cherokee country 4.0 l

Question edited to fix second code.
Grand Cherokee P0700 Code Definition If you are scanning your vehicle right now, you should be looking for a second code that tells you what is actually wrong. Think about it like this.

• P0700 Says- "Hey there's something wrong with this transmission.
• The Next Code(s) Say- "I'm the actual problem going on with the transmission. I'm what you're looking for."

You need a scanner or a OBD code reader, on this system there is no manual check. Follow the link to see what you need. OBD II CAN Code Reader with Multilingual Menu

Are there any trouble codes stored in the computers memory? A code reader will allow you to read trouble codes if any exist. This is the first place any tech would start a diagnosis, otherwise we will only be guessing a repair solution.

if i remember right code 45 is oxygen sensor, it shouldn't cause a drivability problem but should be replaced as it controls fuel mixture

Disconnect the battery cable for a minute. Might work.

On the side of your transmission will be a switch with several wires coming out of it. This is your reverse switch that turns on your reverse lights and most likely needs to be replaced

Engine compartment, left inside fender, it white, ceramic made two inches by 3/4" bolted to fender wall

I own a 96 jeep cherokee classic and about 12 months ago had similar problem, I managed to find a manual  for sale. Contact your local auto shop and see if they sell a manual for it.
