6L80E and Supercharged
Finally got my supercharger for the vette.... Been long time since I've been blown (I know I know)... Back in 2006 I had a 2004 GTO auto with a Maggie. Amazing....
Fast forward to now... ECS1500 kit. Car has a Pat G blower cam that I put in a few years ago. Trans is stock with stock converter.
Not looking for earth shattering numbers... Been talking with Doug and Matt FSP to hold boost around 6/7lbs. 550 RWP max would be fine with me.
My question is with the trans. How are you guys driving these cars without blowing them up? My tuner is great and we have worked the cal a few different times for the cam. In my GTO, I would be able to punch it doing 60 and it would drop to 2nd and just spin and go. With the 6L80, I'm assuming that's a bad idea to go from 6 to 2nd and go? I drive with the paddles 99% of the time now, so would be paddling down to 2nd or 3rd and punching be the better route for highway pulls?
What about a 35mph punch?
Thanks in advance...

But you're on the right track with keeping the power down below 600 and ALWAYS paddle down before matting the gas and it SHOULD live for a while. If you forget to paddle down and just kick it, you will drive thru the clutches. It might not kill it the first time, but it will certainly wound it.

Good tips there.. Don't let it downshift more than 1 gear. Use the paddles to get the gear you want for a highway pull. Tuning and keeping it cool is the key. Done right it can live a long time.

(when floor it along with adrenaline pumping, I am sure I will forget paddle up)

While a good tune and/or Alto clutches (both of which I run) can help make the transmission last longer, there are still limitations on the internal hard parts which absolutely get stressed when you try to downshift more than 1 or 2 gears at a time.

Another option is to have the tune set to upshift even in paddle mode. I have mine set that way in case I forget to move to drive, or don't have time ..

I don't use them to upshift. I use them to get down to the gear I want.... lets say third on the highway, and then floor it and push it into drive and it will shift itself. It is just the violent kickdowns you have to avoid.

Now another question, with my current tune my TCM had most of the TM off which turned off the rev match on downshifts. I'm assuming I want more TM now with the blower? How much more?

A 6-2 downshift in a 6L80E is hands down probably one of the worst things you can do to it. That applies regardless of whether the car is bone stock or supercharged, or if the transmission itself has been tuned properly and/or rebuilt with stronger internals.

Running mainly street tires, do you see 600 rwhp lasting on these transmissions? I rarely see the track, maybe a few sticky launches but I am mostly a street guy. Not quite related, but my 4l60 in my 99 c5 was supposed to explode when we put a 150 shot to it. 80k miles later it was still shifting fine, so I try to take everything with a grain of salt.

my problem when i paddle shift down to the gear i want, the moment i floor it and bump it into drive ....... it automatically shifts up.Cant stand that. I have to wait for it to rev out then hold the up shift down and keep it down till it goes into auto mode. Pretty neat you can change it to auto shift in paddle mode. Didn't realize that was an option

use the paddles for a highway run 2nd gear for 40mph or 3rd gear for 60mph. My trans was bone stock for 2 years of 660rwhp using the paddles for upshifting and downshifting my trans never messed up once. I have probably around 100+ street pulls on it. Had it rebuilt last summer with upgraded clutch packs and now have 845rwhp and so far so good.
