6L80E/6L90E/8L90E/6T70E Transmission Tuning is a website designed to answer all your technical questions involved with Impala tuning, Camaro Tuning, CTS-V Tuning, Corvette Tuning, G8 Tuning, Escalade Tuning, and Truck Tuning. Specializing in vehicles equipped with the 6L80/90 transmission, the 8L90 transmission, and the 6T70 transmission. Whether you drive an ImpalaG8, Vette, Camaro, CTS-V, Escalade, or even a Pickup, if it has a 6L80E/6L90E/8L90E/6T70E,  I can help. From stock to wild, low stall to high, you’ll find all the tips and tricks to getting your jewel running smooth.

For a small fee of $99.99 you will have a FULL YEAR of access to pages full of frequently asked questions, tuning articles, tune/config files, tutorials and images and 2.24, Beta, 3.0 and 3.2! You’ll also have access to a "Members Only Forum" in which you can directly ask me any technical questions not covered in the FAQs/Articles pages. You can "key word" search the forums to find previously answered questions other members had.  Minor tuning tips will be available at no charge, however if we need to make significant changes there will be an additional tuning fee.

I go by the name "waker" or "wacker" on the forums and have thousands of satisfied customers with over eight years of dedicated 6L service.  We will leave no stone unturned, we WILL find the problem/solution. I do tuning support for many major speed/rebuild shops and have thousands of hours loging/tuning/testing my own 2010 test Camaro. I’ve ran a dozen different converters from 1800K-6000K stall and three different 6L80E transmission mods. I can also steer you in the right direction with all engine tuning whether FI or NA.  Most, if not all late model vehicles rely on the MAF to be dialed in for ALL driving conditions.  As we modify our vehicles, we inevitably change the amount of airflow being delivered.  In many cases, the MAF needs re-scaled to correct delivered torque values.  I can determine via logs if this is necessary and walk you through the process.

My software of choice is HP, but my knowledge is the vehicle.  If your software has a similar table, I can steer you in the right direction.  I have EFI and HP tunes on the site available for viewing and can tune with either one.  I can determine via the logs if the tranny is burnt or vehicle is simply tuned improperly.  This is a VERY complicated tranny, if not tuned correctly it will have a very limited life under any power over stock.  I've been in your shoes, let me give you the tools and save you some future pain/money!

Why pay to subscribe, simple, I've garnered a very specific degree of intellectual property that others simply do not have.  This is my hobby/passion!  My time/effort is unmatched and my fee will be an after thought once you see what the site/I offer.  Whether you're a beginner or avid tuner, I can help you through the mystery of the 6L.  Sometimes guys get their answers in a few threads, others take weeks sometimes months.  What that means to you is, there are no dumb questions and I'm in it for the long haul. 

What our users are saying

"Very happy that you did this site. Sure helps with the "my​steries" of the 6l80e. First time using your information had me come back after the test drive proclaiming that this was the best 6L80 that I had ever driven. Well worth the money for the site. Tremendous, thanks"

"I was having a 2-3 shift problem that I could not fix. One of the big so called tuners offered to help. Sent them my tune and nothing. Even did a follow up and still nothing. That's when I got a PM from a CTSV forum member hooking me up with (wacker). Great guy and knows how to tune this tranny. His customer service is top notch also. Problems all fixed and the tranny feels great. Just want to give a big thanks to him and all of his hard work.  Thanks"


"Steve was critical in helping me achieve my goal of the fastest CTS-V thru stock exhaust. His troubleshooting skills to help solve some of my issues are incredible. He's made my car shift like stock under normal conditions while still producing ~750hp at the flywheel and running low 10's in a full weight sedan. His understanding and willingness to explain how the 6L80/90 works has been amazing. Without Steve, im not sure I would have been able to achieve my goal. Next time out, we are going for 9.99 full weight, and thru stock exhaust. I'm sure he will be able to ensure we have no TCM issues and thus meet that mark"  DONE!!!
