Hey all! Just deleted my 14' added a 4" FLO-PRO and accidentally put it on level 5 (150-200+ HP) was actually not meaning to do that. and had some fun to test out my new MM3 tuner from DRD. Trans is now slipping into 3RD and 4TH. It shifts kinda hard into 1st and 2nd but that was occurring before the delete. Gears after. 3rd and 4th are fine. Pulls nicely on the highway. I've tried it going slow into the throttle and heavy and it does the same. So my question is should I just check the fluid and possibly change it it/ replace filter or am I on the wrong side of a possibly rebuild? Also could it be something as cheap as a new converter and valve body? (Would go aftermarket obviously) I say cheap because compared to a new transmission it's cheaper obviously. But any advice would be greatly appreciated! Thank you
