The changes in gears both up and down are very erratic, and far from normal,there is also a suspicion that the torque converter is playing up.
DTC warning light is permanently on, and is not working at all.
BMW won't touch it without a hefty diagnosis fee upfront and don't really want to know owing to the modifications.
The car was red flagged by BMW quite some time ago,and his only real option is a good indy.

The Quaife LSD has helped alot but some decent tyres should finish the job nicely.
