Hi all, first post after a lot of reading.
I have had issues slipping 4th on slight inclines with very little throttle. eg: slight accent on the road roll off throttle into ascent and speed drops off, rpm climbs like severe clutch slip. eg: 5000rpm 4th no response until i pedal or grab 3rd. I had replaced trans a couple of thousand ks ago after burnt 3/4 due to same slippage with Mrs driving. Under load even towing trans feels great 100%.
pressure gauge doesn't drop, fluid levels are fine, temp within reasonable range. I'm worried by the time i diagnose issue 3/4 will be gone like before rebuild. Trans builder set tune. I am hoping for a fix to lockup 4th until sort out engine tune as i feel its triggering the slip.
Log file shows slip 30:5 minutes in. Trans log added shows PWM spike 96.9%
