4R70w Drain Plug

[LSUpete]

I’m changing the fluid in the 4R70w (2001) and the plug washer isn’t worth reinstalling. Who has a source for a magnetic drain plug?

The pans don't have a factory drain plug. You are dealing with something aftermarket. And no telling what aftermarket parts you have.
Measure what you need and find a universal sealing washer that matches. It is the only way.

cool.

I have the magnetic plug, but the washer gasket is torn, so I'll probably use a copper washer....unless you have a better suggestion.

Make sure the copper type washer you use is fairly soft. If not a quick annealing will help it seal.

Not knowing what you are working with, sure, sounds like a good plan.
