i installed a brand new th200 in my car awhile back, and ever since i cant get passing gear to work. also the car used to shift at 4000 rmp's at wot and now it shifts at 3000 rpm's. when im not at wot the car will shift at like 1800 or 2000 in most gears. and when it goes into 3rd the rpm's are like 1200 and it will kinda bog like a stick will if you shift too early. i set the detent cable and it didnt help. i took it to a tranny shop and they set it and it didnt work. they inspected the cable and said it was fine. i checked it and it looks fine. so what could cause this to happen?????? any help would be appreciated. thanks E.
