Trans Dip stick tip..

I might be a weirdo, but I have never used the bolt on the dipstick. I didn't think it was necessary...29 years and counting on my race/street car.
It’s a good idea to bolt it in with a locking dip stick. The stock dip stick will just pop out of the tube if the fluid gets overheated. I ran a stock tube for years without it bolted in also. Never a problem.
