Best way to install Tranny drain plug?

[askoop]

Planning on dropping my transmission pan and changing filter and fluid next week. I stopped at AZ today and picked up a B&M drain plug kit. Stupid people somewhere put a huge sticker over the back, where the instructions are. I tried to get it off, but the print came with it.

Anyway, what is the best way to install the plug without welding. I would like to weld it, but dont have the ability, tools or connections.

I was thinking of wrapping the threads in teflon tape, and maybe using some red or green lock tite.

Any other suggestions to get this right the first time?

Thanks!

I would not use teflon tape. Although it would help seal the threads it would also lubricate them so that it may come apart too easily when trying to remove the plug. It would also interfear with the Loc-Tite.

Since you don't want to take that portion of it apart again, use the strongest Loc-Tite you can find and make sure it sets up before putting the pan back on and exposing it to oil.

J.B quick epoxy.
Perfect sauce for your application.

Either JB Weld or have someone weld the plug "base" into the pan for you. Any other methods ARE guaranteed to leak or weep ATF. You can leave the drain plug threads bare....I've never had to use anything on mine over the years and have never had a leak from the drain plug. The best thing to do is see if there's a deep trans pan available for your trans...most all deep pans have drain plugs and you'll get more fluid capacity as well to help with cooling. Just my opinion.

I installed the same drain plug in my pan and used the nylon washer that came with it.No leaks,weeps,drips....nothing. I also use teflon tape on the plug that inserts into the drain.BTW,i'm a pipefitter/welder,and IMO see no use in welding it in the pan unless you are not going to use back up to remove the plug.

Isn't this a flange/bulkhead fitting? That is, an externally and internally threaded piece that you insert through a hole and then tighten in place with nut/washers to seal the flat surface area (the only place you don't want the fluid to escape) and a plug that goes in the internally threaded "pipe"? Works well. You just have a fear factor of unfamiliararity.

Very well explained Gary!
