Tired of trannys
 

New to the site , i have a 05 cummins i use for personal and work so its had bad days and be ready for alot of post from me in the future you guys . So my tranny has been out for about a year because the cooler went out and mixed with the coolimg system . And when i finally put it in the shop i told them more i want it built more heavy-duty than stock but i dont need flashy shit put on it i pull some shit sometimes hardly ever tho but i want it to get it when i do tow . And ivd had it out of shop maby two months now so my question is If i had a bully dog gt tune and i uninstalled the programming because i didnt like having it , and a day later (today) my tranny shfted pretty late and slipped once , and i checked the fluid level and its on the bend of the dipstick "witch is quite over full . Would the weird shifting be from having the tranny shop over filling tranny or uninstalled programmer ?
