    I have encountered a issue with my allison. When I'm not towing my 5th wheel sometimes the truck when downshifting ( coming up to a stoplight ) will downshift hard at around 10 to 8 mph. The tranny temp is at 190 ish, no codes, no service engine soon, nothing, and it does it 2 or 3 lights in a row, then back to normal. Someone said this might be the throttle posistioning sensor ? Any help anybody ?

    I tow a Saturn as well and installed the plates and wiring myself. While I will never do it again it is doable if you have basic skills and it is an AWD Saturn Vue. I did it during August in Texas and had to have my head examined afterwards!!
