05 Denali Put in D for drive but felt like Neutral

[latvius]

The other day I got in the wifes 05 Denali and put in drive but it felt more like it was in Neutral so I stopped from rolling put it in neutral than back to drive and all was well. My wife told me she was at the car wash and put it in neutral but it acted like it was in reverse.

Anyone else seen this? Gear selector getting worn or transmission or something else?

Check the linkage down at the tranny.

Almost sounds like it's slipping...

If it's on the correct gear (confirm it is), and you rev it and it doesn't go or only crawls, then it's slipping.

Nah that ain't it. Haven't been able to duplicate it though.

Change / refresh your ATF. If you're feeling frisky, have your old ATF analyzed.

Sorry to hijack your thread--does anyone know which trans filter our nbs takes?

Sounds like the shift cable is going bad.

And Tony, pretty sure all of the full size vehicles got the "deep" pan on the 4l60e

The one with the 4 little "feet" under the filter (matches the "deep-pan" style oil pan.)

Back to the OP...
I checked the linkage because I read about others having the snap on cable connection disconnect from the transmission lever but it was all tight everything looked good.

If that linkage was messed up, that definitely would've been best case scenario. I messed up the linkage once in my old Express van--I ran over a huge cone--and it had a similar issue that you had. Did you look really good at the plastic ends on it?

Yup looked in perfect condition

Could be your needle isn't correctly aligned up at the console. The cable may be good, but it might need to be adjusted.

If it was my 84 K30 sure but this is digital, somehow the gear selector tells the gauge cluster electronically what gear it's in.

Sounds to me like it's the neutral safety switch where the linkage hooks up. They are known to go out.

I've replace several though the years in my nbs vehicles.

You may have thought the truck was in Drive and in reality it was in Neutral.
