While driving home from a doctors visit, my 2004 Acura 3. 2tl would not shift into 2nd gear, the engine would rev up but the car would not move, rpm's would just jump up and down like it was stuck in neutral. I shut the car off, turned it back on and it worked fine for another two miles before acting up again. I took the car to harper Acura of knoxville and they suggested I get a power flush of the transmission and that would most likely solve the problem, so I agreed. Later that day I picked up the car, (richard, service manager) said they flushed the system, added some type of gel additive to lock in whatever was lose inside the transmission and that the more I drove it the better it will be. Well I took it home, drove it around and it kept acting up, I didn't think anything of it and kept driving per richards suggestion. Car still slips out of second gear going up hills or at traffic light. I'm having to shut the car off in the middle of traffic and then re-start and drive off, but I'm afraid if I keep driving like this, transmission will completely fail. According to NHTSA there is a recall on the power transmission for this year and model car however according to Acura, it doesn't apply to my VIN number even though the car was manufactured in 2004. Acura corporate office wont explain why my transmission is not recalled,however others are and their from the same year, model and manufacturing plant. Now I have to figure out how take my two year old daughter to school every morning and risk her safety as well as mine in a car with faulty transmission that Acura doesn't want to take any responsibility for. My car only has 83,000 miles on it.
