Th350 broken vacuum modulator bracket tab
 Driving down the road after a fluid change all of the sudden I'm spewing fluid all over the road. After a $60 towing bill and time to get around to examining I find my issue. Vacuum modulator, and bracket both missing. Assuming the bolt bracked out however, the tab apparently broke at some point in the trucks life and was simply bonded back on. What's the best possible way to reattach it as its simply a 1/4 wide piece of threads and I plan on doing a 700r4 swap in a few months. |

NEVERMIND
Think I figured it out... When I did the fluid change someone had wire wrapped around the crossmember. Me not thinking anything of it as it didn't look to be doing much I cut it. Guess I figured out its purpose after all |

Always interesting how these trucks were "fixed" throughout the years. Never get away with it on newer cars/trucks.

Longer bracket bolts to the extension housing. https://www.transmissionpartsusa.com...-00047307b.htm

Re: Th350 broken vacuum modulator bracket tab
oops, edited. I was working from memory and it was written right there in the link! Part works great BTW, for some reason I still had to use multiple o-rings on the modulator to keep from leaking/sucking air though.
