I would really like to see a auto trans tuning(Holley) discussion. Cameron Powers has been a huge help the past few years, but it would still be great to hear tuning tech. Thanks for sharing knowledge
Jake taught a bunch of the stuff I know about 4L80es. I might try and put a "how to tune your 4L80e" video together with all the pertinent stuff in one place
I recently rebuilt my early model 4L80E with your stage II kit for a crew cab 4X4 truck. The mistake I made with my 1-2 shift was when I did the TransGo AFL valve bore modification, before I did a full rebuild on my trans, that comes with a spool valve that has an inner and outer spring. I removed the inner spring for a firmer 1-2 shift...that was a mistake on a heavy duty application with a stock torque converter. When I did a complete rebuild on my trans I installed that inner spring back in. That did the trick, and now it shifts right for a truck application. I took that TransGo 3-layer plate and trashed it. I did the internal dual feed, and installed a stock plate that I drilled out all the shift holes to the smallest .031 diameter. I also did all the mods that your stage II kit comes with such as the output roller bearing. My 4L80e will probably live longer than I will.
I currently run a holley terminator X without transmission control and I am in the process of switching to 4L80. Would I be better off going with a US shift guick 4 over a holley terminator, X that can control my transmission as the one I have currently does not. I ask this question because you mentioned in the video that the holley Terminator X shift strategy leaves some to be desired. Is the shift strategy better in the US shift quick 4? For context my set up makes around 1000 hp in a 3200 pound truck.
I learn something from every one of your videos. Thanks!!
Thanks Jake. Always good info

Yes, the US QUICK 4 has adaptive learning and is more user friendly. It is RPM based with throttle percentage for shift points.
I wish I knew 10% of what Jake knows about transmissions.
