Exclamation X5 E70 Transmission Adaptation Values

I was hoping someone may have insight on my transmission clutch adaptation values. I'm using ISTA and read my current values and they're posted below.

Do these look within spec or wildly out of spec? I'm looking around and can't find much data on appropriate spec.

Thanks!

Existing adaptation values of the automatic transmission:

Clutch fill pressures:
Clutch A: 329.0
Clutch B: 362.0
Clutch C: 234.0
Clutch D: 294.0
Clutch E: -450.0

Rapid fill times:
Clutch A: 38.0
Clutch B: 19.0
Clutch C: 13.0
Clutch D: 0.0
Clutch E: 108.0

Clutch B: 109
Clutch C: -171
Clutch D: 207
Clutch E: -24

Fill times
Clutch A: 28
Clutch B: 4
Clutch C: -12
Clutch D: 0
Clutch E: 9

Yeah I cant see anything either in ISTA or INPA that suggests proper value ranges. I reset the adapts and drove it around a few times so I’ll post the updated values soon.

Thanks for posting your values as well!
