2002 Mercury Cougar possible transmission problems?

I got the car 3 Christmas' ago with 29K miles and it now has almost 70K. For the last 6 months or so the car has been stalling/pulling a lot. while I'm driving, while I'm reversing, while I'm about to park, when I try to accelerate. pretty much whenever. Lately, the battery light has been coming on too? I took it to a mechanic and had it put on a machine, nothing came back wrong for the engine or any sensors atleast. Passed inspection, but I've been told they don't check the tranny. Any possibility this could be a sign of the transmission going?

NOT LIKELY. SOUNDS MORE LIKE ME PLUGS ,WIRES. THAT WOULD BE THE FIRST PLACE I WOULD CHECK, NEXT FUEL FILTER,THEN AIR CLEANER(FILTER)

Not likely. Most mechanics miss this. This is a VERY simple fix. I am sure you have probably put fuel injector cleaner in your gas tank. Hoping that it would take care of the problem. When cars had carburators, that would work. Since your car has fuel injection, only half of the problem was solved. With a carb, both fuel AND air mixes together, and any dirt that made it through the air filter was washed down past the throttle plates and was washed away.





With fuel injection, the air is seperate from the fuel, and as such the cleaner does not go by the throttle plate. This IS easy to fix. What happens is that the small particles that get by the air filter build up on the throttle plate, or butterfly. The only way to clean this is by doing it manually. DO NOT use carb cleaner. There is a specially formulated TBI cleaner that is safe for injected intakes. There should be a rubber or plastic housing or tube that comes from the Air Flow sensor to the Throttle Body. Loosen the clamp that holds it to the TBI and pull it to the side. Look at the Plate, it will probably be real black. Clean it front and back with the cleaner, and don't forget the bore. Put everything back, start the car, which will be rough because of the fluid flooding the cylinders. Once it is cranked, go for about a 15 minute ride, then see if that didn't clear up the problem.





What happens is the small dirt particles start to clog the idle air bypass on the TBI, the computer will compensate for it up to a point, but eventually the computer will say screw it, and give up.





Check your battery connections, at the battery, the starter, and the chassis ground before even thinking about replacing it. Make sure they are clean and tight. Also look for the engine to chassis ground strap, check for clean contacts and deterioration. If need be, replace it. Check your belts for signs of wear and tightness, as they can cause the alternator to not turn properly, causing the battery to not charge enough.





Hope this helps.
Reply:your car brand is know to have tranny problems all the time thats why they are not expensive. an bye the way you described whats going on i would definetley say the tranny is bad!
