I ourchased a chevy dually with a three speed tranny. It seems to be a good truck but it drinks gas and iii put too much trans fluid in it and now i cant get it right because the rubber thing on the dipstick is giving me a falty reading. Anyways now i am having trouble even putting it in reverse or shifting into a gear. It slips now too because of the overflow of fluid. I just want to know if it will shift easier if i take out some of the fluid or should i get a new dipstick and drain all the fluid and start over. I dont want to risk burning it.
