When driving at road speed (35-60), particularly when the engine is not warmed up, I recently developed a "miss", a stutter or hesitation, when applying the gas. I thought it was an engine miss at first and replaced plugs, rotor, cap, etc. Engine runs fine. Now I think the "miss" may be in the transmission. If I'm driving and give it a bit of gas it feels like the engine is miss firing, but I think it is the transmission skipping. If I punch it down enough to drop to a lower gear, the stutter stops and engine sounds fine. Once everything warms up, everyhting seems to run well.
So, could it be a punch-down switch on the tranny or something in the transmission that is acting up? Anyone else ever have this occur? Of course, I hope it is something simple, not a major transmission problem.
