No, the trans is in the correct gears as selected by my foot. Can start in 2nd or select 1st with further push. Thats how I reduce the problem rather than staying in 2nd. When considering the trans problem I thought maybe a bad TC that is locking too soon and perhaps not fully slipping when stopped (stalling) but trans shop said thats not how it works.

This has been going on for many months now, along with mentioned filter/purge, I dont think that biocide is necessary?

Still suspicious of the IP.
