Finally got my 750 with trans program error out of the shop yesterday, after one month. The local idiots tried the old game of start replacing everything until something works. And then they gave up. One quick call to Jeff to advise him of the problem.. Took him about one minute to figure it out, and he was 100% correct. A $34.00 trany speed sensor, that ended up costing me $450.00 in unecessary repairs. JEFF, THANK YOU !!!!!!!!
