Hey guys,
I went on a vacation to the mountains last weekend and when my truck would down shift when going about 70 the rpms would run up a little too much and then the transmission would catch bring them down a little. Is this transmission slippage? My truck is a 2000 f150, 4x4, 5.4, 4r70w, with around 130,000 miles. I do regular oil changes with the tranny and engine and always use Royal Purple with the tranny. Can anyone give me some info on what may be wrong?
