Question type: Maintenance & Repair

My sons Cougar reveved up (came out of gear) on his way home. The transmission then re-engagged and all seemed ok. The next morning he drove it about two miles and the same thing happened, but this time it wouldn't re-engage. When you first start the car, the transmission will engage for about 30 seconds and then nothing (the engine just revs). Because there were no warning signs of a failing transmission, I think maybe it's an electrical problem. I replaced the Transmission Range Sensor, but this didn't help. Any thoughts or suggestions.

Also check the fluid level and the filter. If the filter is plugged could give these results. When you have pan off check for how much wear debris is in pan and on filter. This is a good indication of the condition of the tranny....Could be PCM I would check all the connectors on it first. To do this unhook the negative terminal on battery for a few minutes then unplug and replug all the connectors, reseating them.

I have a 2002 Cougar 5-speed, V6 that is having a major oil problem. It's leaking on the motor & my tail pipe is completely black. Small small oil spots on the ground as soon as I put it in park but no major puddles. The smell is awful & it's smoking when I park it after driving it. Had my oil changed on a Wed and by that Sunday, it was completely dry. Not even enough to wet your finger. Please, any ideas on what may be causing this???? 1 Answer
