Finally found the solution. I went back into BIP to reconnect the traction module and clear out all the errors. Jason measured the height of my front and rear tires and there is almost a 1 inch difference with the rear 265/35's being the taller tires. He recommended that since he had some mounted 255/35 tires sitting there, let's try to see what difference it would make with tires all the same height. I am game for anything like this. Hooray!!! After 10 hard runs up to the red line, not once did the transmission light come on!! I am so relieved!! You guys in the earlier posts were right! I just did not go far enough in getting the tire heights the same. I have already scheduled two rear 255/35's for mounting this week.
Anybody interested in two Michelin 265/35x18's with about 2K miles on them?
Now on to the rest of the to do list.
