Ok so what would cause my tranny to not want to upshift. It will not shift out of a low gear. Which puts me at about 3400 rpm to do 35-45 mph. I started on me out of the blue. At the same time as a high ideal problem. Is it a electrical sensor? I drove to work after washing my Jeep with no problems but as I left about 4 hours later the problem started the minute I started the Jeep up.

 

Did you spray your engine down when you washed it?

 

Yes. But not like majorly but yes.

 

TPS, 2-3 shift solenoid, 2-3 accumulator piston/seal, transmission band.

Then there is always shift linkage problems.

 

Stop washing your engines, it does more harm than good.

 

Then there you go you most likely shorted out some electrical components probably got wet a d weren't completely dry when you started it up and shorted them out.

 

Where is the 2-3 shift solenoid? It's in the trans it's self right?

 

I was washing off the under side of my hood, it was caked in mudd.

 

You gotta think though all that water drips somewhere I'm sure the motor got fairly soaked in the process

 

Fixed it. Was a bad tps.
