Ok , i'm going to Meineke this morning and see how good they are at welding . I hope it won't cost me too much . Thanks to all of you guys!

 

I don't know that I've ever heard of teflon tape causing problems. If you wrap the tape only around the threads that come in contact with the transmission case, you're minimizing the chances that a shard of teflon tape will come free. I'd also like to add that the transmission has all sorts of metal debris floating around in (which is why they recommend magnets at the bottom of the pan) it, so I fail to see how a little teflon tape could damage things.

Our friend danpicos overtightened the drain plug, hoping to avoid leaking transmission fluid. Had he used a little teflon tape, he could have avoided overtightening and having to get the transmission case welded.

I'm at work right now, but later on I'll check my helms, chiltons and the internet more to see if I can verify the use of teflon tape on a transmission drain plug. As of right now, I'd think you'd want to use teflon tape.

 

Kind off getting OT, but I am pretty sure the teflon tape has the opposite effect: it reduces the friction (it is teflon...) allowing you to tighten it further that you typically would, it also fills spaces between the threads.

 

ok guys, just to keep you updated , the car is at COTTMAN transmission shop right now, and the guy told me they will do their best to fix it without taking the case off .He didn't promise anything but he said , he will drain the fluid very well for a couple of hours and then he will drill a hole at the end of the crack so it doesn't spread , and then he said he will will put weld, i'm not sure if he meant epoxy JB weld or some aluminium weld material like that thing that you use a blow torch . I will see in couple of hours if it worked or not.

 

I realize it's off topic, but something I think needed to be clarified. By taking up the space between the threads, you're making it tougher to tighten the bolt all the way. Having use teflon tape on various plumbing projects at home (shower head, washing machine), it makes it more difficult to tighten a bolt or attach a nozzle as you're squeezing more and more of the tape into the threads with each turn.

It's the same logic as cleaning the debris off of your studs with a wire brush so that your lug nuts go on smoothly (and you avoid cross threading).

Hope things work out for you Danpicos!

 

Hey sounds good. drilling the end of the crack is actually a really good idea. He may plan on brazing it, which is similar to soldering but if done right can be extreemly strong, but you will still have to be really damn careful in the future.

Just be glad is wasn't an RSX, don't they have some weird Mg alloy cases or something?
