So I have a 95 GT (automatic) and whenever I floor it, the transmission doesn't release the gear when its supposed to, and when it does i get a terrible jerk, or it only changes the gear when I release the gas. Its completely stock except for a cold air intake. Spark plugs, spark plug wires and Cap and rotor are brand new. its timed correctly, the TPS is fine, it runs perfectly except when I'm at WOT. When I press the gas half throttle it runs great but not its full potential, I haven't checked the transmission because I really don't know much about them, anyways any ideas on what the problem could be?
