trying to get the drain bolt sizes for all my fluids, wondering if this would be a good or bad idea? I am mostly attracted to it since i stripped the drain plug hole on the transmission fluid a year and a half ago, my temporary fix has been to use some silicone sealant and it seems to be holding up fine. I know im not going to be down there often, but it would be nice for ease of change.

From my past thread I know that the Transmission drain bolt is M14 and 21 mm long.

Info on the Oil and Differential Drain bolt sizing would be helpful and overall impression on the parts/ idea. i just dont want to have to go through the terror of stripping the drain threads again, that was terrible.

this is terrible, maybe im posting in the wrong sub forum? or it is just really that bad of an idea

 

A few members swear with the fumitomo drain valve...but I'm a strong advocate against it.

If you have a problem with stripping threads....don't leave yourself open to leaving the valve open or accidently having it come open.


JMO.

There is no way that the Fumitomo valve can accidently come open.
There are two movements that must be completed to fully open the valve.

 

I don't have any expierence with fumitomo drain valves, but looking at it I wouldn't put it in my trans. The drain for the trans is on the bottom of the case, and I'd fear something would catch and rip it off from normal driving. I think there's a reason the stock drain plug is low prifile and close to the trans body.

I would put a helicoil in your trans and get some thread back in there. Just be caseful tapping in with the metal shavings.

But seriously, how did you strip a M14 bolt? I know it's an Al case, but you're either way over tightening it (I'm sure there's a torque spec on it), using an air gun (not a good idea), or doing something really strange. What's the story?

 

they did. not all of them busted open but there's some went nut and bursted open.

just use a good washer and take it easy on the bolt, they last forever if you take care of them

 

my first fluids change i knew practically nothing about the car and was so stuck on torquing to the right psi i didnt even notice that the tranny drain bolt didnt have a washer (no i didnt forget it just didnt have one)... so i tightened the thread down without the washer and subsequently stripped it.

 

im a pretty careful person, i just seem to have a lot of bad luck. im sure it would be pretty hard to leave the drain valve open, as when your filling it back up all the fluid would just leak out anyway...

 

Please see your original post.....


That's what I thought.....

 

i appreciate all your thoughtful input.... ignore
