Hi, I'd like some friendly advice regarding my ZF please. It is currently flaring between gear changes after a tune was done. I was told the ZF was returned to stock temporarily for whatever reason and to drive it for a couple hundred kilometers so it can learn again etc (previously tuned by a different workshop with torque limiter removed apparently).. Few times already I've received trans and dtc failure messages and then it doesn't change gears at all until you turn it off/on again.
What is the best cause of action?
As a side question. Is there such a thing as the mk2 ECU's being
