Q: Crankshaft positional sensor and transmission speed sensor code is on with check engine. Can they be related? Can the transmissio
My RPM's are about a quarter higher than normal. When I hit about 60 and accelerate my car jumps/misfires and doesn't want to shift. At lower speeds it does fine. And, If I ease into 75mph it doesn't jump or misfire but switches gears smoothly but still rides a tad higher on the RPM gauge than normal. Also, it comes and goes. This happened a few days ago and I took it to a mechanic and it stopped, ran smooth all of the time and the check engine light went off.
