Art,

I am having the same problem and we’re troubleshooting this now on a IV-P with a TruTrak DFC 250 Autopilot.  I have the problem when selecting altitude hold.  Otherwise if I just engage GPSS it will hold course but once the altitude hold is engaged then I get a left banking tendency.  When tested on the ground with selecting the VSI + or – I get a left turn command from the autopilot.  Zac from TruTrak is working with me on this.

driving it with a GNS480, in GPSS it just goes into a slow
bank to one side, it could be operator error. What benefit
do you get from the auto pitch trim?.
