Allstar Performance ALL69121 Locking Transmission Dipstick

I had a leaky 727 transmission tube on my 64 Polara. I had already removed the stock tube once and tried a new O-ring, with zero luck. My car is not original, so having an aftermarket tube and dipstick did not matter to me, so thought I would give this a try. It’s a great design as the rubber boot sits down in the transmission and then the tube fits into that. Seems to have fixed the issue. The only negative was the tab that mounts to the transmission bolt was not bent correctly and I had to tweak it to fit, but other than that, it’s perfect.
