    Need advice on an 07 yukon denali transmission its a 6l80e

    Sounds like you took it to a flat rate shop. "flat rate" is an industry term for shops that literally do as little as possible to slap/patch a transmission back together for a much lower price; 30-90 days is the typical warranty. More than likely, frictions other then what were bad, were reused...

    Hard Trany shifts. Q’s for the pros

    Sure, no harm in doing so plus you familiarize yourself with the trans. Worst case, it doesn't fix it and you just yank out unit and go through it. Meanwhile, you still have the shift kit in the VB, new harness, etc which can go right back on during overhaul.

    I know Syracuse is a few hours from Long Island but if you can't find anyone in town to do the work, you can call Gary Ferraro at AAA-1 Transmissions - he's in W. Hempstead, I believe...Chris Kirkonis at CK Performance is also on Long Island so either can help you directly or perhaps refer you...

    4L60E? If so, 3-4 clutch pack is wiped. Time to yank it out and overhaul or replace it.

    2019 Tahoe Torque Converter Replacement

    Wow, that's odd...I would think any trans shop could simply swap in a reman unit...Many of the transmission shops in Vegas don't even bother rebuilding later model units, they just buy a reman for about 50-60% of retail, sell it at retail along with the R/R on top and make a tidy profit. If the...

    2007.5 yukon denali high rpm 2nd-3rd late shift

    When it comes to those check balls, replace them all with torlon check balls in the Sonnax Zip kit. Also carefully scrutinize your spacer plate for wear and replace it if you see the check ball seating locations becoming enlarged...When the #1 check ball gets stuck, you lose all forward...

    2007.5 yukon denali high rpm 2nd-3rd late shift

    Still don't know what you were referring to by dumping it for 2k or dumping 2k into it....What did you mean by that?

    2007.5 yukon denali high rpm 2nd-3rd late shift

    Do what you want but you're taking shots in the dark without the proper diag/testing equipment...I'd take it to a trans shop that's versed in those units and have them do a full diagnostic work-up...If it were my vehicle, I'd drop and bench test the TEHCM and VB so I knew for sure that it was...

    2007.5 yukon denali high rpm 2nd-3rd late shift

    That's a likely suspect casue, not a diagnosis...You really need to pull the TEHCM and valve body assemblies down and bench test each using a DVOM and Test Block (TEHCM) and Sonnax vac test machine and 6L test plates (Valve body). But generally speaking, 2-3 flaring is the beginnings of 3-5-R...
