There's nothing special about this valve.2015 GMC 2500 Duramax w/Allison
I spoke to my tuner and he had suggested to replace the stock Transmission solenoid with a new solenoid #29541895 to increase line pressure before he does transmission tuning.
Has anybody done this and opinions?
It's in every Allison from 06 six speed to present.
