2017 Allison EPC solenoid plug

Does the 2017 Allison still need this to keep line pressure up at all times?

Deviant makes that plug. It’s cheaper through them. I didn’t think the valve body had to come out for those plugs, mike? I’ve always just done the solenoid mod like mike said

That price is in Canada pesos. So like $60 US. What's the solenoid worth? About the same from some of y'alls allison dealers down there iirc. I'll check online again.

$70 for the solenoid from the allison dealer in calgary. So I'll probably go that route. P/N is 29541895.
I've got 45k miles on the truck now so I know the oil is still good but i've got an 8 y/o sealed pail of Transynd that I need to pour into something. I don't think oil goes bad does it? Other than water contamination.
