It may seem like a dumb question, but I can't tell you how often I've found tiny oversights to be the cause. too big of a job for me to do so i guess its going to have to go to a trans shop. If there is something wrong with the engine crankshaft position sensor or the wirings, you can see a fluctuating RPM speed. Sometimes it builds speed and shifts properly sometimes not, it runs at about 3000rpms before shifting to high gear sometimes 2500 when running right. RECALLS! But, more often than not, its going to be the spark plugs or coil packs that are the culprit. There are a number of things that can cause transmission shifts, including high RPMs, leaking transmission, vacuum hose leaks, the Clutch being worn out, and solenoid problems. If you notice that its just while accelerating or just while idling, then youll probably have to replace either the fuel pump or the air filter.
