I have a 03 Denali 175k the transmission slips and the engine revs between gears. under light throttle it is not noticeable but heavy throttle it is much more noticeable. the fluid was a little low so I added some but no change. is this a common problem? Do I pull the pan and check the filter or is it hopeless? the fluid looks good. any ideas? thanks

if it is loose under heavy throttle and not light pressure either the plates or bands are on there way out or you may have a filter obstruction of some sort and are being starved of fluid enough to make them slip. If it started suddenly and continue to get worse then you may have to have it torn down for inspection if a filter change does not help.
sorry looks like i posted in the wrong section....the truck was like this when I got it.. it was a crash repair i purchased . so I am not sure how long it was like this. I will have to pull the pan and see what the filter looks like. hope for the best! thanks

Trans are the same aren't they?? Does sound like a band slipping ... you can try some Lucas type stuff but it's a bainaid at this point I would think ...

yea once the symptoms are there, the only real fix is to replace.

In the Future whenever you do a tranny service always replace the boost valve, it controls the line pressure and when they wear the fluid will bypass
and the clamping force on the clutches will suffer.
once they slip they are toast.

well i will check the filter... funny thing is that it seems to shift firm into 2ed gear firm 3rd is a little soft and I can see the rpms jump as it shifts into 4th. At this point is a boost valve worth the money or just bring it in if the filter is OK?
