Sonnax line pressure booster worth it? Pro's Con's?

Joe.G · Sep 17, 2016

Hi, I have a 04 Ram 4X4 Hemi, What do you guy's know about these?
Are they worth it?
Do they hurt the life of the tranny or do they help it?
Does it change the way it shifts?
Do I need to use the spring? I'd rather wait to add that part when I do the next fluid change if I need it.
Thanks

Easy instal no need to wait till fluid change.
Worked great for me.
Noticeable difference in shifting
Did a custome tune and it gave me a code. Hemi fever said the line pressure booster did it.
Everything I have read says that it should help the life of your tranny (by no means am I an expert) theory is higher pressure the more it cerculates, the more it cools, the cooler the tranny the happier it is (to an extent). At least that's my understanding.

If you want I have mine some where. It's used, but I'm sure we can work something out if you want to try one.

Sonnax said it may give a code if you use a tuner and tune the tranny with it and then add there booster, How old is yours, I guess they have 2 different designs.
