I am going to keep playing with FB Live on Sundays - I will pop something up that morning to and suggest a time or topic. You are happy to comment here if there is anything you want to give me a heads up on and I can prepare a topic. My hope is by having these vids will cover common questions transmission related or wild and off topic and potentially cut down on phone calls. Business, pleasure, life...therapy... I really don't mind.

ADVISORY: It looks like the industry has not finished discontinuing and obsoleting things I really need. Holley no more SFI bells (hit and miss anyway) and finding TV cables is a joke other than Lokar. We lost TCS previous to this and they had amazing parts. So sad!! I will continue to do my best, however for now, SFI is pretty difficult :(

WIth that said, if anyone has any SFI bells for the AOD or 4R laying around they want to part with...I might be interested!!!

Scraaaaap ! :)
Time to purge stuff I have been holding onto for who knows why.
In this business you often hold on to things that "might" be useful, as anyone does, but it adds up to a lot of literal dead-weight. The shelves were collapsing. I still saved about this much even still. But the AOD reverse drums have to go...they are completely pointless to hang onto and heavy as heck. Valve bodies...AODE, pre 96 castings, stuck valve junk AOD,mostly all damaged in shipping frankly.

This vid is to document a few things. A Transtec employee was flagged and took notice of my previous post. If I got any info wrong or changes in the works I'll update you all for sure. Enjoy 😉

For all you AOD lovers out there. You have probably noticed (or should have) that the valve body gaskets are horrible. I have mentioned numerous places on the web for 10+ years easy. See the image below as a perfect example of how a VB install can make your life so hard. Do yourself a favor, center the gasket, open the gasket holes where needed, and glue that SOB in place with some thick grease or stickum. There are some very critical holes being covered here. Partial cover is one thing, but to blind them, that will cause some serious headaches.

If you want to dive deeper into this issue, look no further, let me sum it up. There was only two toolings ever made for the AOD gaskets. Ford and Transtec. WHere Ford tooling went, IDK, where Transtec tooling went was FNST. Tt sold the tooling no longer making money with it. FNST makes 100% of all the AOD valve body gaskets since then. They only have access to crap gasket paper as a lower quality / mass production aftermarket company. There is no money in gaskets, so, makes sense. So that is the short story. Any gasket labeled with a FORD PN or the words TRANSTEC on it, are king of all gaskets and fit properly. WHY is that...because they are made from proprietary paper composition and post die cut treatment to seal them from moisture so they do not expand. FNST does not have access to this good paper or treatment.

Thanks
Bye

P.S., yes you will see the gasket below was poorly placed to begin with, but that is how things go when you are working above your head below a shower of red. S**t happens.
