Gday. I have a BF mk2, zf 6 speed. Just had it tuned, and it started flaring only at high rpm at wot. Not crazy power, only 275kw. After driving a couple hundred k's, tge transmission is now flaring wildly (will just shoot to redline until I back off and allows the next gear to engage) on all gearchanges above about 2500rpm. Checked oil, level is fine and has not mixed with coolant in the heat exchanger.
Ive already got a replacement box from the same year model xr6 turbo to use, but thinking it might be an idea to figure out what failed and rebuild it just in case the new box has any dreams.
Does anyone know what component of the zf would cause these symptoms? And where to buy replacement zf components?
Cheers,
Lionel.
