TCI 6X, no electronic engine braking
I would like to start a new thread and get more input on this issue, I previously posted my story about the problems with TCI 6X and lack of engine braking under Opinions on 4L80E converted 6-speed automatics on this site. TCI is of no help and they don't care about Pro-Touring cars evidently, so I have been searching and calling other tech advisers ever since I installed the 6X in an effort to figure out a way to get engine braking in electronic bump shift mode. I thought I had found the answer with Sonnax Smart-Tech overrun clutch valve kit 34200-40K. It looked like a good fix and works on a 4l80e valve body for engine braking. But then I saw detailed posts from years ago on https://www.hotrodders.com/threads/6...-4l80e.285594/ which had pictures of the TCI valve body, and it looks like TCI has an extra solenoid in the valve body where the Sonnax Smart-Tech kit would be installed. I am so frustrated as the PCS 6 speed valve body had electronic engine braking and TCI does not, and they will not do anything about it. As I have mentioned before TCI's advertising on what the TCI 6X is used for which includes Pro-Touring cars is totally misleading.
Simple put is there anyway to make the TCI 6x valve body do engine braking in electronic shift mode?
If not, has anyone put a standard valve body in a 6X with the Smart-Tech overrun clutch valve and just used the transmission as a standard 4 speed with the TCI TCU?
