Engine revs rise at odd times - gearbox?
Driving my 2003 E53 Auto, once in a while the engine revs rise a few hundred rpm before settling back down. This happens only when I'm going uphill and I've listened in closely as I at first thought it sounded like it was changing gear but I notice it is actually staying in the same gear. It's like I've just blipped the throttle but I haven't.
Everything runs OK but I'm nervous about it being the symptom of gearbox issues.
I've had the car for 12 years and it's only started happening in the last few months.
Any help appreciated.
