Is the valve body mod a benefit to do on a 5th gen auto tranny? I spoke to a person who had it done and they said it was worse for them cuz they replaced 3 trannies. I dont know their driving habits and they had a few mods done (bolt ons and engine tuning). Is the mod worth it?

 

The VB mod is supposed to help a lot and it should extend the life of your tranny since it shifts faster.

 

only worth it if you drive aggressively and or race. for regular driving, mixed in with some spirited driving, dont bother.
i have one for a few years now (along with a tranny cooler), and its a love/hate relationship.

 

I drive aggresive and I love it, no tranny issues what so ever. As mentioned above though its a love hate thing. People hate it because of the hard first gear shift, but I love it, especially when the tires spin . But not better then stick, thats why my car go buh bye soon for another max.
