Let me chime in on the transmission FILL and DRAIN plugs...
(begin rant) I have no clue why people tighten these SO TIGHTLY! It's un-necessary. In my former life I was a licensed Journeyman Plumber (Ret.). Actually, I guess I still am a licensed Journeyman Plumber - just not employed as such... What in the crap does this have to do with transmissions you ask?? THOSE PLUGS ARE PIPE FITTINGS (well, they have pipe threads...)
So, now that you know that I am eminently qualified to speak on the subject:
- Go the Home Depot. Plumbing Department. BUY an entire roll of TEFLON TAPE.
- Go home. Properly apply (ya, just wrap that sucker up with tape) the teflon tape following the manufacturers directions to the male threads of BOTH PLUGS - BEFORE you install them.
- Tighten the plugs (BOTH PLUGS) ONLY ENOUGH so that they don't leak! There is NO pressure inside the transmission (like there is in your Natural Gas line or your galvanized water pipe) SO THE PLUG DOESN'T NEED 80 FT/LBS OF TORQUE. Seriously, you can practically screw them in by hand if you use teflon tape or good pipe dope (just kidding (exaggerating really) you need to snug them up.) But you really, really can stop over tightening those plugs. How do I know? Come and remove these plugs from MY transmission. Be a plumber - even if you don't want to - for me...
