Trannyman95... there is one odd behaviour that I am assuming has to do with changing the stock torque converter with a 2800 stall torque converter. When cruising on the highway at 60 miles an hour... at the slightest change in grade (going up hill and I do mean slightest) it seems the transmission slips because the revs will go up about 500 rpm for about a second and then back again, and I can feel the car get weighted back. It will continue to do this untill the grade levels off again. Is this PCM again or something else?Originally Posted by Trannyman95
