If you call TA it will be! PTC is about the best for a "check out" and fix if needed--TA will charge you same as a new unit --no middle ground with them. I can't answer your original question but good luck. TA 10 in units were always a little loose in high gear--too much slip compared to other stuff IMO--I have had TA J units that were without doubt the best I have ever used FWIW
