Customer Question

I have a 2007 Ford Explorer V8 2WD with 127,000 miles. The problem first developed with hard shifting under hard acceleration. It has gotten worse over a few thousand miles and now seems to hunt between gears if you are light on the throttle between 40-60mph. If you step on it enough to make it kick down, it goes away and will normally settle into gear. It also seems to "bump" when coming to a stop.

I understand this has the 6R60 transmission, and doesn't seem to be plagued by the common problems the older 5R55 had. I need to know if I should be looking for a new transmission, or if there are common causes that I should diagnose first. Thank you

Hi, my name is ***** ***** is usually caused by a bad torque converter lock up solenoid, and is common, when you are cruising beween 40 and sixty, and it is hunting for a gear, can you lightly depress the brake pedal, not alot just enough to turn on the brake lights and see if the hunting goes away?

Tim, I have not been able to get it to exhibit the hunting behavior again yet, but would a torque converter lock up solenoid explain violent shifts under hard throttle?

Yes it can, butcan also be from another problem, the hunting at cruise speeds is almost always the TCC solenoid, and is a very common repair, the tcc solenoid is inside the transmission an, bolted to the valve body, this would be the first suspec, is the fluid a bright pink and full?
