Q&A

My van 1997 Plymouth Grand Voyager SE 3.3L, died while driving, speedometer go down suddenly and motor died. I check signals for injectors, crank sensor, Cam sensor, pump gas, and all ok, I replaced the computer (PCM) and the solenoid module transmission and the problem continued. I test the van with park position for more of 30 minutes and don’t fail. Only while driving for 5 miles fail and then wait for a 1 hour and the van works again another 5 miles and so. Is a problem because I don’t know if will turn off on street traffic quiet or on highway traffic heavy. Please give me directions for this problem. Note. My scanner was displayed several codes, initially problems with gear 2 to 3, then Thanks.
