2001 CHEVY SUBURBAN 1500 xl 4x4 w/ autoride, 155K. no past issues and no simptoms prior to last last. start car, drive about a 1/4 mile and the tranns slips and will not drive forward. tried revers and had gear for a few seconds. If i turned the truck off and waited a few, when i started it i could then get it to drive for a few hundred yards and then the gears would slip again. not sure about service intervals but because of this i figure the auto trans fluids and filters have not been done as they should have been. Tow it to a tranny shop or replace tranny filter? any insight would be hugely appreciated.Jerry Hendrickson Washington

tried all different gear options (auto) tried X XXXXX XXXXX options. shut truck off, restarted and was able to get gears for just a short time. ( a few feet to as much as a few hundred yards) Checked fluids and all seems normal. thanks for any advice.
Hello, I'm Cam. Please include all the details about your issue so I can accurately advise you. I cannot see your vehicle so please be detailed.To start off, can you tell me the exact colour, shade and level of the transmission fluid?
darker red color, fluid and level was showing a touch high. Did smell a bit on the burnt side.
Is it possible the fluid has a hint of brown or black?
well possible but based on the dip stick it is still transperant and redder in color. In addition after i would let the truck sit, i would start it and could get movement, then there would be "slipping" then i would get a bit of a grinding gear sound. not real bad but not real good either.
What happens if you put it inXXXXX?
nothing changed, also hit the tow haul button to remove from overdrive and no change. while playing with things i can feel it select the gear, try to move forward then just spins so I assume the gear selector is connected correct as i could get movement from time to time
Okay, that is what I feared. 100% honest I think you should simply replace the transmission. Slipping condition in reverse and forward as well as into wheel drive and four-wheel-drive make this very clear. Clutches inside the transmission or the lip seals and controlling passages have fail. Normally I would suggest a rebuild or repair of this unit but considering and how reasonably priced the GM remanufactured units are an incredible warranty that they carry a replacement almost cheaper. The warranty from General Motors covers transmission for parts and labor for a period of three years, or a distance of 100,000 miles, which ever comes first. And the cost of this transmission is usually $1900. I know if I was to buy the transmission from GM for my vehicle which basically the same as yours, I could get it at cost for roughly $1750. Furthermore, knowing what I know about this particular transmission, I honestly believe that replacement will be far easier yield less headaches in the long run.
thank you. no point in doing a tranny filter and seal? Just replace it? seems odd that there was no big bang and no past symptoms.. I guess its not smart to think that a filter would just all of the sudden clog either...?
The chances of this being a clogged filter are slim to none. There is a chance this could be the seal the seals filter, but the damage may already be done to the clutches.
