Answer #2 100%.... NEED to SCAN & monitor live trans data to verify and find the CAUSE. MAY be an unplugged connector or bad connection/wire , but without knowing input/output signals , can't tell for sure. best to get it fixed! High rpms won't necessarily damage engine , but unless you know EXACTLY why the trans isn't working right , you just might be dooming it quicker.

Yup , it'll burn some green jelly!!---...347,000 on sunday.
