transmission pan gasket

my transmission pan gasket is hosed. took it off last year, cleaned in up, and used a new gasket but no gasket maker or anything. its now starting to fail again. i understand about being too tight and warped the pan and all that. do you think that a lube locker gasket plus gasket maker is going to make it last longer than a year?

if i dont have a torque wrench is there any way to determine how tight is too tight for the pan bolts?

one more thing, i've seen a lot of different theories about how to use gasket maker. is one big bead going to work, that will theoretically squeeze out flat when you put the pan on? i've also seen the guys on trucks use a thin bead all along the mating surface , spread out by hand(finger).

install the lube locker dry - no gasket maker. if you have the original steel pan the trick is to lay it upside down on a flat surface and using a flat brass punch and/or a thin block of wood, even out the entire sealing surface of the pan and make it perfectly flat, especially the holes where the bolts go through. Then install the pan following the lube locker instructions to the letter, using the correct torque and sequence. do not overtighten and distort the pan.

As a rule to torque without a torque wrench on pans and valve covers. Grab the top of the wrachet wrench where you turn it forward and reverse and wrist tighten. Do not tighten them by the handle.

If you have a good sealing surface there is no need for rtv or anything else. But a little permatex aviation cement is not a bad thing to hold the gasket in place for the installation.

If you don't have a torque wrench, get one. Or at least borrow one long enough to get a feel for how 15 ft lbs feels. When you measure that much torque you will be surprised at how little it is and realize that doing it by hand you were probably going 2-3 times more than that; which is the source of all the stripped or broken bolts and dimpled and leaking pans.
