    Did you make a new video with the traction control and stability control turned off? That first one has too much interference from those two to determine if there is a problem.

    Sounds like it starts to slip in the middle of second gear? I hear tire spin, then none, then spin again.

    could be the TRQ management in the factory tune AND belt slip. i got another new belt and mine stopped doing something similar. HOWEVER, you can tell the TRQ management is still kicking in. waiting to get my full tune done again since we got all the other issues fixed up now.l

    Re: 2008 cadillac STS-v transmission issues

    I got what appears to be a tranny issue. When I'm in automatic mode, going at moderate acceleration, when the car shifts from 4 to 5, you hear the car shift, then it hesitates, revs go up a little, then appears to "catch" and return to normal driving in 5th gear. It causes a hesitation in acceleration so it's noticeable. I've noticed this happen very occasionally in other gear changes, but can almost always replicate it with the 4 to 5. Also, I usually drive in "manual" mode, and although it is much rarer, I've caught this happening a couple of times.
    On another note, (I mention this because it may or may not be related) when I'm in manual mode, under moderate acceleration, when going from 4 to 5, the car will sound like its switching gears, only to cut back in, in the same gear. In other words, instead of 4 to 5, itll go from 4, then cut out like its going to hit 5, and say never mind and cut back in to 4. Then, as speed increases (less than 10 mph later) it will automatically shift to 5 on its own. Is this normal? As you guys can see I have an 09 and it's got just over 52k miles. Any help is appreciated and I thank you in advance.

    It's only in second... That why I don't think it's belt slip. My old Harley truck had slight belt slip but I was under load in different gears... Timmy's is exactly right, it kicks up and down up and down.. In manual mode, first gear will spin to redline, shift to second and it will do it in 2nd regardless...

    In the 2nd sentence I say "you hear the car shift" where I should've said "you hear the car attempt to shift."

    Whatever it's doing, I don't believe it to be correct. Luckily it's still under Cadillac warranty and they are supposed to have a loaner car ready for me Monday. I will keep you all updated.
