ok..I stripped the tranny drain bolt...HELP!!!

[gogle]

Well...how was I to know the torque was only 15 Ft Lbs....never mind that I have my 100.00 service book only 10 feet away....What are my options? heli coil? or what? thanks in advance...Garth

ouch..yes I would think a stripped drain plug in a transmission lends to either a heli-coil perhaps as a second option to just replacing the pan. not sure what a new pan costs but a tranny is mighty pricey!

 

[gogle]

I was thinking....I have never done a heli-coil...therefore I thought about JB welding it...then next time I can either drop the pan...or a tranny cooler line and just pump the old stuff out...I did that many times before....or...I think I have heard about a self tapping bolt?? what do you think?

The monkeys at the local jiffy lube stripped mine ( wife took it to get tranny flushed- 2002 DC 4x4) and I made them get me a new pan- I think it ran around 200.00

ok...here is what I found out...a new pan from the dealer is 123.00 and there is such a thing as oversize drain plugs...they are meant for oil pans....but I guess it should work...so i was thinking...does anyone know the size of my tranny pan drain bolt? all I know is it takes a 14mm wrench to remove it... just wondering....Garth

14mm would be an M10 (for JIS bolts). You could drill it out and retap as an M12 - I did this on my motorcycle drain plug and it worked just fine. Just don't drill into anything important.....

 

[gogle]

ok....that sounds good...where do you get the M12 bolts? would the cheap auto part stores have one??

 

[LukeZero]

Hardware stores (ACE, TrueValue, etc.) or home centers (Lowes, Home Depot, etc.)

Possibly an AutoZone, Advance, Checkers, O'Rielly etc.

 

[gogle]

what would the thread pitch be on a metric bolt? does 1.5 sound right?

 

[LukeZero]

M12x1.5 would sound about right.

M12x1.25 would be fine thread.
