Tranny delay/slip when starting out?

I am new to chevy but my 2004 tahoe has slipped on two or three occassions since i bought it a month or two ago. At a light, i hit the gas and it didn't go. I let up on the gas and hit it again and it took off normally. I bought it used with 37k miles. The only other thing i notice is the tranny from first to second has a very slight bump. It isn't very noticeable, and not bad, but not silky smooth like the other gears. I have had no engine or tranny lights go off and the issue from the stop light shows no other symtoms, but i find it strange.

 

any ideas? should i be concerned or no big deal?

Sounds like the old "starts in 2nd sometimes" issue. My original trans did it a handful of times per year. My completely rebuild trans does it with the same frequency. It also did it with my stock tune and my wait4me tune. I'm thinking it is a programming issue where under certain conditions it mistakenly selects 2nd gear. I can now tell when it is happening so I ease off the gas and it goes back to first. When it first happened, I gave it more gas and it kind of slammed into first. Bottom line for me is it doesn't happen enough to spend $$ on it.

If you are good enough buds with your service advisor, he/she could get it done for free by GM.

For example, I just had my slip yoke changed out for the nickle plated one and front U joint done under factory warranty at 63,000 miles.

I have had this problem from day 1. The dealer flashed the PCM and it does it less often, but it still does it. I have never been able to duplicate the problem reliably. If anyone can, post it here and tell your dealer so that the programmers can debug it.

It happened in my wifes 04 Tahoe on the way home today. I can remeber it happening about 10 times or so in the 3 years we have had it.

 

I need to bring it in for the rear seatbelt recall.....I will mention the TSB - do you have the number of it ?

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
