Equipment problem #1

My vehicle went from driving perfectly to startling and not going pass 45 in a matter of two days. I was getting all maintenance done at dealer always on time had just service it. When all of a sudden it started making a jerking/ skipping feel as if I was accelerating too hard. Took it to get checked and the code that came up was (tcc)torque converter clutch. I spent 6000 to rebuild the transmission and kno the engine has a tap tap noise. Once again I took it in and now it’s the lifters in the engine. No warning light have ever popped up.

Equipment problem #2

Hello, I’m calling about the gm transmission recall recently announced in March 2025 affecting 2020 Yukon vehicles. My Yukon experienced what I believe is the exact same issue described in the recall. Our vehicle lost forward gears and almost caused a crash. A certified mechanic confirmed the transmission fluid was burnt and full of clutch material, with internal transmission damage. We are asking for this to be handled under the recall, as the issue directly matches gm’s known safety defect. We need this resolved immediately — the vehicle is unsafe to drive and the failure happened before we even knew about the recall. Our GMC mechanic stated the following : needs immediate attention recommended service transmission: test drove verified no forward gears after 3 minutes of driving. Fluid brown and burnt full of clutch material. Internal damage to transmission. A transmission flush is a process that makes it possible to clear the old transmission fluid from the vehicle's transmission. This process also helps to remove residue of older transmission fluid from the converters, coolers, and cooler lines that often are part of the design for the transmission.

Equipment problem #3

Transmission is shaking when I start driving. !!!.

Equipment problem #4

The a/c unit stopped blowing cold air intermittently. I'm taking it to a mechanic to find out what's going in. It's a 2020 for goodness sake.
