Hey guys, I bought my 1500 2 years ago with 142,000 miles, I've put 30,000 miles on it since and I'm just starting to have problems. I do mostly highway driving and usually cruise around 70-75mph.
A few months ago I noticed when I shifted into drive or reverse from park it would hesitate, rev high and then lurch, a few times it lurched hard enough to stall the motor. It feels like drive/reverse isn't engaging in a timely manner, it takes maybe 1-2 seconds after the shifter is positioned for the truck to move. It used to idle at 550rpm steadily, now it fluctuates between 400 and 1,000rpm about one cycle (from 400 to 1,000 and back) every 1 1/2 - 2 seconds, it's not gradual, it sounds a oddly like someone slowly hyperventilating.
So, shifting from park to drive it lurches forward (identical in reverse as well). Slowing down to a stop from any speed is also problematic, it keeps the rpm up near 1600 just before and a few seconds after stopping, like the engine doesn't want to follow the shift pattern when gearing down. An added bonus is it takes more brake pressure and longer distances from my stopping point to engage the brakes. Just after stopping the truck still tries to creep forward at idle. The throttle is also unresponsive until about 1/2" depressed and revs up very quickly, as if to make up for the 'dead spot'.
It shifts late, it really likes to wind out each gear,if I'm taking it real easy it shifts; 1st - 2nd at about 1,700 (10-15mph), 2nd - 3rd at 2,400rpm (35-40mph), 3rd - 4th at 3,100 (45-50) and 4th - 5th at 3,500, these numbers are averaged, it's never the same twice. Shifting takes longer than it should, it kind of hangs on 4th while cruising, occasionally shifting into overdrive. All problems mentioned occur warm/cold, long/short drives, up/down hills, city/highway, you get the idea.
Transmission fluid level is dead nuts halfway in between the full/add markings and it's slightly darker than it should be. I've been meaning to change the fluid & filter but read some info about transmission slip and wanted some input before I remove the pan twice. So there's 2 band adjustment screws that are occasionally loosened or otherwise need readjustment for proper shift timing every 50,000 miles or so. I'm familiar with how adjusting the set screws can affect (sometimes horribly) the overall performance and is hit or miss when done at home (according to others' testimonies). I know it takes accuracy for tightening to the 72 Inch/lb and then back 2 7/8 (please explain to me how this works, I'm fairly mechanically inclined but transmissions have eluded my interest until recently).
Check engine light comes on occasionally, it's elusive, when I do hook up a scanner it read some secondary auxiliary exhaust code, probably due to the 3 feet of tail pipe I lopped off over the winter. I backed up into a seemingly shallow snow bank, sunk in, and bent the tail pipe into the tire, no other damage was done but it had to go. No other gauge cluster lights are amiss.
So, fluid and filter are getting changed, what else do you think can be done at home. A best estimate at getting a shop to do any of this work and how long it should take would be helpful as well.
Thanks
