Steve, help me out, My 300 was struggling to stay in 4th gear. Every time I tried to accelerate, it would downshift to 3rd and would stay there until I totally got off the gas or put it in neutral. Tried all the usual stuff, modulator, change fluid, filter (not blocked), shift linkage. Had the control pressure cable end adjusted and "BINGO" problem solved. I'm confused...
