New here, I'm having an issue with my 04, 1500. Heres what it's doing. I'll b driving along at almost any given speed in o/d and #1 it feels like it has a very slight case of the hiccups. #2 it will suddenly pop out of o/d and rpm's will go to 2200+ @55-60. basicly the same as tow mode. I can stop, shut it off n restart it and it'll b fine. I just changed the fluid, n filter with no change. the fluid was in decient shape and no parts or shavings in the filters or pan. I have to imagine that it's a solinoid, but witch one? Also, the one n only time I used the tow button, the tranny got stuck for a day in that mode.any input will b helpful thanks
