4L60e 2nd gear issues
When im just easy driving very little gas leaving a stop light my truck starts in first then somtimes goes to 2nd and then third normaly. AND then somtimes starts in first then trys to go to 2nd then seems like it skips 2nd and hits third.
shifts are kinda sloppy, seems like a line pressure and mabe a shift piont issue.
but not sure. when i put it in tow/haul mode it hits all gears solid no slip and feels fine, even at WOT 1st-3rd. just wondering if its mabe a tuning issue that i can take care of if i get it tuned, or somthing mechanicly wrong with the trans, or mabe PCM related. any ideas?????????????????
