I just spent several hours at our local transmission specialty shop. They have been in business since 1959. I had a transmission leak found by my oil change shop. It was a leak on the sol-box on the front of the tranny. It tells the tranny when to shift. After it was done and fluids and screens serviced I sat down with the owner and asked him about my concerns. he said to watch and listen for the tranny hunting for a gear when in overdrive.If
this is happening often then use 3 (PRND31) . The cooler is adequate under these circumstances. Watch the color of the tranny fliud.When its darked red it is time to change. All in all he said that my 2002-Dodge Grand Caravan 3.8 L
with tow package should do just fine! I consider this the ultimate blessing for the suitability of TV and it's towing features.
