700rwhp + Built 6L80 / 6L90 Questions - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

John_C · 01-31-2019, 08:30 PM

Guys, my 2010 6L80 is not happy with the new HP from the ProCharger D1X.

It's slipping on WOT pulls now.

It only lasted about 2 weeks at 760rwhp!

So I'm looking for a new built trans that can hold 800rwhp.

Who makes the most reliable 6L80 / 6L90 trans?

Should I swap to a built 6L90 with custom drive shaft or will a built 6L80 live?

Since tuning is the most critical part of making these live, I need a good trans tune. I'd rather get the trans from a builder that includes the trans tune. But if i can't get the tuning with the builder, who's the best at tuning these?

The trans tuner needs to have a proven history of 700 + rwhp heavy cars out there living as a daily driver with spirited driving (WOT Mexico runs) and dragstrip passes.

Asking too much?

Do they do the tuning?

hammdo · 01-31-2019, 09:08 PM

Yep!

Ryan will be tuning mine after rebuild...

Talk to Aaron @ GPI. He can get you hooked up...

If you have it, can you list the parts and upgrades they did for the 800+hp build?

Do they upgrade to the 4140 HTSR Billet Reinforced Output Carrier for 750+ rwhp like Cricle D Trans?

On a side note, I had a Level 5 RPM 4L80e put in my car. 750 whp. It lasted 2200 miles before the sprag was history. I had it rebuilt locally and the shop said most of the parts were OEM 4L80e parts. I would not recommend them for any car, except the guy in the other lane at the drag strip.

Shop that did the blower tune had nothing to do with the slipping.

I having mine done this month. I have a flare from 4 to 5 and I’d rather not wait. I’ll have all the details once it’s done...

Still runs nice, just when road racing, want to know it will handle shifts...

66,500 on it, fluid changes every 5k to 10k miles, depending on how many races...
