Do you mean that the 2-1 shift is harsh during coastdown to rest (rollout) or when you apply power? The harsh 2-1 rollout shift is obviously a very common feature on the 6HP26 transmission, but less so on your 5HP24.

There’s several people who have the same issue over on the Range Rover forums at the moment (which also use the M62 engine & the ZF 5HP24 transmission) and I’ve recently stripped a valve block down for one of the forum members to see if that might give a clue as to what’s causing it, but his valve block was absolutely fine.







I’m interested that BMW say there’s a software upgrade for the 5-speed as well as for the 6-speed. The Range Rovers use Bosch GS8.60.1 rather than your E53’s GS8.60.2 but, even so, I’d be very interested to know how you get on with this.
