Next service of my 11.5" - I'm going to apply teflon tape to the bottom drain plug and fill hole - I have a very slightly oily film build up around both. (Can't go wrong with PML).

One thing with these ATF thermal by-pass delete blocks installed = My ATF temps never get even close to 175-180*F - supposed the ideal temps to check your ATF level on the dipstick.
I barely get to 158*F during the summer months.

So most of us know - ATF swells when heated.

If the level on the dipstick is in the ideal level range @ 170-180*F - Is it always going to read low (with the 150-160*F temps & lower temps)?

Even though you have the correct amount of ATF within the 68RFE.

Yes Lubelocker gaskets are the real deal - Will also use one with my PPE 68RFE pan install.
