Well I have had this code now for over 12 months

I have been waiting for the gearbox to fail or at least start to play up.

So far nothing. Gearbox is performing well.

So Guess Code 17125 isn't that bad after all? ie Gearbox death sentence?

I contacted the ZF specialist here in Australia and their comments were along the lines of "if its not locking up. Don't worry about it, only down side is your using around 3% more fuel"

I have had the transmission pan pulled and inspected and the oil is perfect and no metal bits.

Am I just lucky?

Cheers, John
