  • Stripped tranmission fill plug

    Yup. stripped it.

    I've tried to get a pair of vice grips to clamp on to it, and break it lose. No dice.

    I have a B&M short shifter on my transmission. Can I still remove the shift lever and fill the transmission up with fluid like that?

    I normally like to do the transmission fluid change using the fill plug because I like to see the fluid come out of the fill plug; proving it's filled properly. Plus no, fill plug, no way to check your fluid level.

    Tips anyone?

    what i've done is just measure the amount of fluid your putting in to spec. and yeah use shifter hole.

          As stated the game plan is to fill the tranny with fluid through the shifter. Get it to a shop. have them remove the old fill plug and put in a new piece.

          Does anyone know if the fill plug from the differential can be used as the fill plug on the transmission? I was thinking using that plug it'd make it easy to use a universal 1/2" piece to an extension to my impact gun. Easy removal of the plug every time.

          I know I know, shifter fill works fine. I'd rather use the fill plug.

            dont use an impact gun.....those plugs shouldnt be that tight. Or when you put soemthing back in the hole make then tight, but not where a gun is needed for removal.

              Torque for that plug is stupid low.. if you put it in that tight, it's possible to damage the tranny case since it's alsuminum and that's a tapered fitting. by the time you're putting 50-60-100lb of torque on that plug, you're putting thousands of pounds of stress into the tranny case. ouchies.

              But umm yeah. for the time being, jut fill through the hole. Next time you have the tranny out, do what you have to do to remove the old one. Should be the same thread and pitch as the diff plugs- but make sure there's room for the magnet inside the housing or use one without a magnet.

                Richard was there when we were pulling the fill plug on my sohc tranny (thankfully with the motor out of the car). Had to tack weld an end-wrench to the plug and beat on it for a bit before it would come out.

                Not good times.

                  Torque specs for the differential fill and drain plugs is 43 ft/lbs. I'll have to look up the specs for the transmission, but I suspect they'd be similar. I normally torque to specs everything that I can reach with my torque wrench. What I can't torque to specs I go with "tight" then I get a little weird about leaks, and get on it a little harder.

                  The fill plug on the differential does not have a magnet on it. The drain plugs for the tranny and dif. have the magnets on them.

                  I've always used my impact to remove drain plugs. Never been an issue, but this is only the 2nd time I've drained it the fluid on this transmission. I never use air to put on bolts. I've always had to improvise a bit, sometimes there isn't enough room to use long break bars or it's at an odd angle. My girly arms sometimes require the use of impact guns.

                          KTC Tool transmission drain plug sockets

                          For those that haven't stripped out their plugs yet you may want to get a set of these:

                          http://ultimatetoolco.com/drainplugs.aspx




                          http://ultimatetoolco.com/ktc17mmsocket.aspx



                          They run $28 each. I haven't purchased them yet but plan on getting them eventually.

                          I've also learned not to over tighten these drain plugs as the threads are an interference fit so if you thread them in all the way it can no longer seal and you get fluid leaks.

                            Treat it like a pipe plug. teflon tape and a light amount of torque.. mine have NEVER leaked and I only torque them to about 15-20lb.
