My 2003 Mazda Mpv has a horrible transmission shifting problem. Took it to dealer and they said it's the transmission control module. They charged me 1,500 dollars to install new and and reflash it and the transmission still doesn't shift properly.
The contact owns a 2003 Mazda Mpv. The contact stated that the engine failed four times. The vehicle had to be towed each time. The dealer installed another engine in the vehicle. The contact stated that the check engine light continued to illuminate and the coil ignition had to be replaced twice. The dealer installed new spark plugs in the vehicle on March 13, 2007; however, they failed a year later and had to be replaced. The dealer also installed a wiring harness. The battery was dying, there was a coolant leak, and the radiator core, catalytic converter, manifold studs, and pcm all failed and needed to be replaced. The purchase date was unknown. The current mileage was approximately 48,000 and failure mileage was 36,000.
My 2003 Mazda Mpv, the transmission shifts hard between 2nd and 3rd gear. You can feel the transmission slipping and then it hits hard into third gear. I have taken this vehicle three times to the dealer for repair. First time they updated computer info, second time they replaced the tcm, and third time they replaced the tranny fluid which I paid for and the problem still hasn't been solved.
1) transmission has very hard shift from 2nd to 3rd gear. Problem is intermittent. 2) occurred at least once a day and mostly in local traffic. 3) took it to the long beach Mazda dealer to reprogram the tcm but the problem still occurring.
Transmission between 2nd and 3rd gear- in the last month or so, we have noticed a hesitation and then hard shift into third gear during regular city driving. We spent 2/16/2004 at the dealership for an oil change, tire rotation, and examination of this problem. They performed a reflash of the tcm/ptm and left the dealership satisfied. About 15 minutes later, it started again. We called back and as of this morning, we have scheduled a drive with the transmission mechanic. I have noticed a number of complaints here and on edmunds. Com. I really hope this can be solved for an otherwise great minivan.
While driving at any speed, the gears in the vehicle seem to be slipping. The gears didn't change at the proper intervals. There were times when the consumer would be at a stop light and the vehicle would lurch forward , as if struck from behind. The check engine light came on and stayed on. The vehicle was taken to the dealer, who reprogrammed the pcm module in the transmission. The reprogramming did not stop the engine from slipping, but it did cause the check engine light to go out. The vehicle has been in the shop for the engine slipping three times, and the problem still persists. The manufacturer has been informed of the problem.
