AW4 Transmission not shifting when hot
Once at operating temperature, my AW4 doesn't want to shift anymore. I can use the T bar and it all works okay, but it doesn't appear to be shifting automatically. Originally I thought it just wouldn't downshift, but now I think it isn't shifting automatically at all.
Once cold, it goes back to expected operation.
I have checked the fluid level and quality, both okay
I have replaced the TPS which made no difference.
Thoughts on this, or recommend a transmission specialist who knows Jeep?
Is it possible to plug in a tester and monitor the signals the transmission is receiving to see if there are any dodgy signals causing this fault?
