ANOTHER 727 QUESTION

Yeah, it was a bang for sure. It shifts fast and good. I was quite taken back when I tried "F" type fluid. Pressure was up and either 5.0 or 4.2 kickdown lever with a blocked accumulator piston. All was good when I drained the "F" fluid and put Dextron back in. I just chalked it up to "not all race upgrades are good on the street". It is an original 383 Formula S and the drive train is good.
Interesting! I too run the blocker rod in my street car. Installed the Fairbanks shift kit, which is the same one I've run in all my cars. Other folks like B&M and Transgo, so guess it depends on what people are used to. Next month I am having the unit rebuilt with heavy duty parts to handle the power of my new engine. And thanks to Kim, I now have a 4 pinion planetary in case the original only has 3.
