Okay when im driving my car and its to the point where i want it to shift and i let off the gas and it goes up a gear.Then if i give it a little bit more gas right after to keep a consistent speed it jerks some. Hard to explain,but is this a sign of the tranny taking a crap on me? tranny has about 140k on it.Also once i put the car in D and gave it some gas to pull out and the rpms just went up then it caught and took off,thanks for the help.
