Hello all. So I have a truck that was built in another shop and ran into tuning issues. We have the engine re-tuned with a new PCM, etc., but the trans will not take a fast learn or slow learn. It stops with a FF error. Has anyone had this issue with any of the ZF trans?
Thanks!
Mines a built '15 as well, I haven't had a problem using my snap-on solus ultra. I've only done it once but it completed...
I was not able to initiate the relearn either with HP tuners. I can get the scanner to read all the parameter to watch the relearn. A trip to the dealer or another scanner, I'm working on getting my hands on the WiTech MicroPOD 2 to initiate the relearn. Fingers crossed it works i'll let you know
The relearn is a bit flakey. It seems to take a few attempts.
But it also takes a LONG time to complete. like 20min or so. So don't be too impatient. It makes you think it stalled out or locked up but eventually you can feel it engage the clutches every so often.
That is soo true... Even doing the adaptive stuff takes multiple attempts, if your lucky...Quote:
