GM.DYNAIR
GM.TFT
GM.GEAR
GM.TCCMODE
GM.SHIFTLAST
GM.SHIFTDELAY
GM.TFMPRS
GM.TRQENG
GM.DYNAIR is included so you can sanity check GM.TRQENG.
If GM.TRQENG goes too low, check your VE table.
And include the TSTATES that Paul mentioned and some of the others, as fits in 24 channels (so you can BB log).
If you suspect slipping keep an eye on GM.TRQENG, GM.TFMPRS and GM.SHIFTLAST.
