rpm vs speed 6l80e

[Area47]

so i was pondering this the other night.

wot shifting.

would setting the mph to zero have the tcs run only off of wot rpm. or would it just freak out and not shift.

reason i ask this is simple. im tired of fighting with the trans. the other night at the track it was hanging the 1-2 shift. would not do this on the street. why? 1 mph change. nothing more.

I can tell you that when i did that with my 04 Silverado 4l60E it was not nice the shifting was not working any better, it actually seemed to shift too soon, like sonner then stock like a fail safe type thing.

mph is my tune is about 6-10 mph lower than the rpm to get it shift at the desired rpm. i pretty much gave up on trying to get it exact. im not trying to do supertune on the truck as it sits. frankly, after 3 years of doing cobalts, im more or less burnt out on my own vehicle. reliability is the main concern for now.

post a snip of your mph vs rpm wot shifts. It took me with help from someone a good 25 runs and logs to work all the bugs after I made a gear change

I just posted this in another thread. You'll get a bog on the shifts if you use paddle mode during the burnout. Once you use paddles, you MUST shift the selector all the way through reverse and back to auto. I don't know why, only that it works. Now we just do burnouts in auto and not worry about it.
