I am seeing videos about Chevy and Fords

TCM tuning makes a huge difference in how the late model automatics shift, both in speed and firmness as well as shift points. At wide open throttle, the tune in the 6l80 will cause my Camaro to jump sideways with the traction control on in the 1-2 shift and then will bark them in the 2-3 and 3-4 shifts. At light throttle is shifts just as smooth as the stock tune. It takes about 1/4 throttle to command any given down shift. A wide open throttle down shift in lower gears will spin the tires if you aren’t on top of pedal management. This is all on the stock ~400 hp ~410 tq 6.2. I tuned it myself and it is a blast to drive. You can clean the performance of them up substantially and you can make them shift just about any way you want with some time and trial and error.
