Re: Please tell me this isnt my transmission !!
Is there transmission fluid? Very low transmission fluid will enable severe gear slip, or instances where no gears will catch as the clutches don't have sufficient lubrication. There are solenoids in the transmission that can be replaced. Some other things to check into aren't as expensive, and if they don't solve the problem they're a regular maintenance item anyway. Replacing the PCV valve, TPS, IAC sensors are a good start. If it's been 30K since your last tune up with new spark plugs - get it done. If the engine light comes on again get it checked right away. There are codes out there that are transmission specific.
I'd spend the $100 or so and get a transmission service done (fresh fluid and filter). If the tech doing the work doesn't see any metal pieces in the pan, that's a good sign that the clutches are still operable and while the pan is off, spend the $50 (or so) and replace the solenoid, located around the valve body.
