Transgo valves should not have any bearing on your garage shift to reverse as they work like stock valves until a certain pressure is reached. You may have a draggy trim valve or something else is causing your rough shift. Have someone with a Tech 2 clear your garage shifts.
There's no codes. What mike means is after a rebuild or any modifications are done to the trans you have to reset its memory. The Allison is constantly adapting and learning your driving habits. When you clear the garage shifts. It resets them to relearn how to shift from reverse or drive and learns how to engage smoother.
Efi or a tech 2 are the most and best ways to relearn the tranny... However correct me if I'm wrong worse case if he has a cts or something similar can also relearn the tranny, just not as in depth process...
The TRANSGO valves have the check valves in the end of them that allow them to go to full line pressure where the stock valves are limited to roughly 125PSI max. The check valves open at roughly 60 PSI commanded, so this allows the TRANSGO valves to work as the clutch packs are engaged by about 45 PSI. This allows the TCM to have control of the engage and release, but once the packs are engaged the TRANSGO valves allow full line pressure to them.
I'm sure others can give a better description of how they work as I have a tough time putting how things work into words.
Gonna jack this thread for a post or two, clarify if a V2 will clear the codes? Sequence for the V2 or send me in the right direction.
