I have a 1995 ACURA NSX-T AUTOMATIC. BLACK, 18 INCH CHROME
WHEELS, WITH ONLY 71k MILES, I AM HAVING STRANGE
PROBLEMS
(GEARS DOWN SHIFTING TO SECOND GEAR) CAN'T GO OVER 45 MPH- NEED YOUR HELP BAD!
Do you think this is a transmission prolem or a sensor problem?
This is what happened: I was entering the Interstate from a speed ramp with the car in manual drive; as I changed gears on the steering wheel from 3rd to 4th gear, the car down shifted back to 2nd, when I got off the highway the car shifted on its own up to 4TH gear and then down shifted to 2nd gear. Acura has checked all of the codes ( Code 15 Mainshaft Speed Sensor and DTC P0700) They check the signals to the TCM, fuel injectors and solenodes;they replaced the solenoids just to test them; they flushed the transmission and found no metal chippings. They checked the voltage levels and ohms (between 400-600).
The car will shift through all four gears automatically on test drives until the engine warms up and then it down shifts back to second gear. Some one please provide some recommendations about what to do about my car down shifting to second gear. Remember the car is an automatic. It shifts through all gears until the engine warms up and then it voluntarily downsifts to second. When you pull over and put in neutral for about 1 minute; drive off and it shifts through all four gears and then goes back to second. I don't think I need a new transmission or a rebuilt one. Someone out there please help me diagnose this problem. My NSX has been in the Acura Dealership shop for two weeks. Do you think this is a transmission prolem or a sensor problem?
