Can a valve body mod get old? Also, if I was going to get a tranny rebuild or a new tranny, could I use the vb mod I already have installed on my existing tranny?

 

well, it doesn't wear out persay, but it certainly can malfunction. There are many valves inside that can seize up, and cause improper shifting... but it's not like it's something you need to replace say at 100k miles. It may run great for 500k miles, it may run for 5k miles...

 

yeah, i always wonder if a used VB will perform identically to a new VB.
