My tranny is fixed
Mod went bad this did the trick. Got an extra hose and oring for future use. 5 stars
My modulator had gone bad this worked great for my 1981 Chevy.
Worked great. 1977 Th350.
Wasn’t as described, no red markings as described.
No red marking
Not as pictured no red strip
Exactly what I expected and more
TH400 vacuum modulator
Works great right out of the box, and much smaller than the stock modulator.
My 1970 C10 had some huge vacuum modulator on it that clearly came from the junkyard. This ORIGINAL style one is a third of the size, and now my truck drives like a new vehicle(kinda lol)! I am completely happy with this purchase!
Perfect form fit and function
super fast shipping and tracking number provided without asking for it
