Hi
I have a 2005 Jeep Cherokee KJ with a transmission problem, it drives fine and when i get up to around 60km/h the transmission slips like its been put into neutral, once it slows down to 50-55km/h it goes back into gear, i scanned the codes and i get P0733 Gear 3 incorrect ratio, so far i have changed to input and output speed sensors and i replaced the solenoid block and no difference, is there anything else i should be looking at?

Is it locking up at that speed?

Feels like it drives fine right up until that speed then its like i pushed it into neutral as it slows down it grabs 2nd again, it has the 42rle box if that helps.

I pulled this from my FSM on the 42RLE

If the transmission will not shift to fourth gear, the
control switch, overdrive solenoid or related wiring
may also be the problem cause.

1st and 2nd are there but i cant get 3rd or 4th, i changed the solenoid block so i'm thinking it could be a wiring problem, would you have any wiring diagrams and pin outs?

What I have is for the 99 WJ 42RLE which uses a separate transmission control module. Do you have that?
