My values before the reset were:

Pressure: -140, 185, -135, -92, 204
Rapid Refill: -2, 26, 19, 0, 0

I had a different problem and the values are quite different. However we both have 0, 0 for refill on D and E.

As you wrote, hopefully Rapid Refill Phil will chime in

I have a bit more info about that case.
Wrote to ZF and they told me that the 750 value might be a leaking E clutch.
Or a failing solenoid. Or a leaky/sticky valve.

I also found an old ISTA print from a year ago, and the values were quite similar to today so i don't think it's related to that recent continuous jerk at low speed.

But possible related to the bump from 2 to 1 which always been here.

Could it be a transfer box or read diff issue?

You can disable the TC by pulling a particular fuse. If the symptom is easy to reproduce you can test if it's coming from the TC. (if your truck is new enough to have x-drive.)

Google for which fuse. When you pull it your wipers may run continuously like the E90 I was working on. You can maybe also pull the wiper fuse.

You can measure your exact rolling circumference: put a dab of something on the front and rear tire such as grease or peanut butter and drive fwd. Find the marks and measure to the nearest 16th inch.

BMW spec is tires within 3% of original size and 1% between axles.

87.6" is the expected rolling circumference most E53 tires.

87.6/100=7/8" must be less than 7/8" difference and actually I just saw that bmw says 2mm max tread depth difference which prob works out to even less.

2225/π= 708.26 mm


2212/2225=0.994 that's only 6/10 of 1% difference.

There are regular threads about jerky performance and even TC self destruct from a single tire being replaced.

Low speed continuous jerk can be from CV or front drive prop. Just throwing that out.
