Nope that’s the ZF8HP torque converter box..this is the Getrag dual clutch gearbox.the ZF is a doddle to service in comparison :thumbsup:

The Getrag was used only because at the time the ZF 8 HP couldn’t handle the torque ..it was limited to 450 nm in most gears and 370 in a couple.

Once ZF upped the torque limit the Getrag was history..

The ZF outclassed the Getrag in almost every regard…
Thanks Peter, good to know.

So the auto in the N20 E89 is reasonably reliable then?

Yes it’s a very good box..oil / filter change every 50k and you’re good :thumbsup:
We choose to go to on with this endeavour at this time and do the other things, not because they are easy, but because they are hard…
