Transmission starting to Slip?

2014 Sierra- 46K miles

 

Last two days I've experienced a possible issues with the transmission that is starting to worry me. The transmission seems to be slipping, maybe? Dunno.  Last nigh I backed out the garage to take the trash can out and left truck running for just over a minute. When I pulled back in, I felt what I would call a slip. Its not the slack in the drive line like when you go from forward to reverse and have that slight "clunk". I am in the driveway so not on the gas hard at all. Just enough to get the truck moving back into the garage and it felt like the rear tires were slipping on a patch of mud or oil then gained traction again a very short distance later. Maybe one tire rotation if I had to guess...This morning Im getting gas and as I pull off from the pump I feel the same slip feeling as I did last night. There were no loud noises or vibrations during this happening. The shift into drive from park seemed to operate normally on both occasions. 

 

Has anyone had this happen or can point me in the direction of whats possible going on? I know diagnosing these trucks can be like figuring out what a woman is thinking in their head at times. I will make an appointment with the dealer but Id like to educate myself a little more if possible before they try and pull their typical "THATS NORMAL" bullshit answer.

Not exactly positive but I do not believe so. Or not more than what would be normal for the load I was under.

If you happen to see the rpm's periodically bounce more than 200 rpm's while driving and feel a clunk, it's most likely a torque converter. Maybe because the fluid was cold, I wouldn't stress it until you can really notice it consistently IMO

Brother my 2014 Ltz Silverado 1500  tranny went out at 52,000 on my way back from a trip to Virginia I was pissed GM took care of it and said the cause was due to the transmission fluid pump failing, they did take care of it though..

Guess Ill hold out a little longer and pay close attention to how its driving/shifting/revs for now. 

 

 I forget off hand what the standard power train warranty is on these trucks but I have the extended 65K LDS warranty so I have some time if shes on her way out. I already used it once for the A/C issues these trucks have.

      Help purchasing a touch screen digitizer

      By mark249 · Posted

      Brought my 2015 Colorado into the dealership to check my touch screen issues, had that ghost touch thing happening. They said I needed a new touch screen and they could either order me one for $500. The lady at the service deck was nice enough to tell me I could order a touch screen online for less, she did stipulate that the touch screen had to be factory OEM, you can't pair an aftermarket screen to my radio seeing it was 2015, it had to be a GM factory OEM only. I found a few on Amazon and Ebay by the numbers on the back of the old screen, DJ080PA-01A GM# 22740886, Some said "OEM" in the description and others just said "Replacement". Would a replacement be the same as a OEM as long as it had the same numbers on the back of the screen? In some of the descriptions they also show different brand names but same numbers, is that an issue?

      I have both but typically use the 4 legged walker (wheels on front, ski's on back).   The four wheeler is starting to be used on "longer" outdoor walks.  The 4 legged walker is particularly helpful in practicing good walking posture.  Both of my knees are at different stages of recovery and I'm trying to not develop poor habits.  I can actually manage with a cane but it's very difficult not to favor one leg over the other.  My PT recommends I continue with my 4 legged walker for a while.  Yesterday was four weeks since my last knee replacement and I'm excited about my progress to date.  It has been a hell of a rough journey so far but it is exciting to witness  systematic and continuous improvement.  I went for years watching the decline of my "mobility".  It seems that everyday now I am alerting my wife to something I can do now that I couldn't a day or two ago!  I encourage anyone facing the prospect of knee replacement to share any concerns with others who have had the surgery.  It isn't an instant fix but rather is a considerable amount of short term pain for long term gain.  Recovery time and pain levels vary for individuals post surgery but the end results are typically very positive and I've never encountered anyone regretting having had the surgery.

      The lifter issue can be dealt with by shorter oil changes and quality oil IMO.

      Wiring Help, Please

      By Core-Lokt · Posted

      I'm putting in an A-pillar pod/gauges, and I'm asking if anybody can identify a (preferably) fuse for a switched power and illumination circuit on the driver's side interior fuse panel. Offhand, everything I checked with a test light was constant-hot, and I'd much rather uses a piggyback fuse. I can certainly find a wire, but I'd rather not half-tap.   Thanks in advance for any help.
