Long story short, I drove through part of a road that I forgot had a big dip, and bottomed out. I was going fast enough such that I scraped the bottom of my transmission cover...There's a pinhole leak now, and I don't have time to take it off and replace it with a new one, along with flushing the transmission fluid ,etc...

You think jbweld will hold?

JB weld seemed to harden like a rock, but I never really tried using it to plug a leak....

Here's the extent of how hard I hit the road...

Sigh.... monday's suck.

I've had pretty amazing luck with JBWeld. It is strong. But if you are trying to plug a leak with oil currently leaking out, I'm not sure how well it will adhere to the oily metal. Long term I would definitely get a new transmission cover.

So... I guess the question now is... Should I go with OEM made in germany for $116....

..Or should I go for some made in china brand for $28 :)

Both will have a 2 year warranty...lol...A pan is a pan, so what difference should it make?

Might as well change the filter, and fluids and seal while I'm at it...

Uhh, flu, if this is your Miata, those cars are pretty low to the ground. After you fix this problem, why don't you try to find some skid plates (for a 4x4) to modify for that car and mount them.

You're pretty handy, right??

That pan looks relatively unencumbered so dropping it and replacing...about a very messy half day job if nothing unexpected is found. When I did my E39 most frustrating part was keeping the gasket aligned while I got the first few bolts back in. I would go with the better brand- German cars seem to leak all the time as it is and putting something poorly made down there is asking for trouble imo.

If you get a skid plate for the miata let me know how it works as I'm thinking about doing it too flu. Put one on my Jetta TDI and have no regrets so far.

That's not for a miata. Its for an Audi.

Jbweld didn't plug the leak. Oh well. Pan on order. I hate doing this job. Last time it was a complete mess.

You might try to suck some of the oil out with a hand pump through the dipstick hole. Also, make a non-tippy plate to clamp to your floor jack and raise it up to support the pan as you loosen the last screws. Lower it down and again pump out as much as you can to lighten the pan. Of course, the xmission will drip 'forever' once the pan is off. OEM part is my vote here.

I have one of these:

It's a HUGE catch pan, and I was able to change my transmission filters on my jeep liberty with no mess at all.

Also, From your pictures, it looks like there's a drain on the pan, or is that something else?

Is this a slushbox? If so, let it leak, let it blow up, replace with a real transmission. Problem solved :)
