Hey guys, after crawling around underneath my car for the past few days i noticed that there was a little bit of tranny fluid around the bolt on the tranny fluid pan. I know a few months back while i was changing the tranny fluid i might have accidentally overtorqued the bolt(Rookie Mistake). The fluid level seems fine it's about 3/4 of the way on the hot reading with the car warm and engine on. But it definitely is actively seeping out of it. I wiped off all the built up fluid around the bolt at the beginning of working on my car and two days later the same amount could be seen around it.

Basically, i know i caused this and it was my mistake. But it will be really unfortunate for me to have to replace the whole pan! I know that could get pretty expensive. Any other little more experienced guys out there know if i could use a silicon or epoxy around the bolt for a better seal? Or should i just leave it and frequently check the level of the fluid. Or just pony up all the money and buy a new pan and bolt? (most likely a stripped pan). And yes i did use a brand new crush washer with the bolt.

Here's some pics:

Use teflon+ RTV if not just retap it? =)?

If there is anything about Toyota that I don't like, it's the tranny bolt. Mine is on the verge of stripping (thank you previous owner for taking the car to a Lexus dealership). All my fluid exchange will be done though the cooler line. All the Hondas I worked on, the pan is damn thick. I can use gorilla force on the bolt and it won't strip because there is at least 4-5 thread in contact with the pan. You can retap if you want, but make sure the metal burrs don't end up back in the transmission pan.

Thanks guys! I'm guna try a teflon/gasket silicon around the threads of the bolt first to see if that stops it. Retapping seems a little risky since i've never done it before, don't want any metal shavings in the tranny pan!

1. remove bolt
2. replace cooper crush washer
3. Torque to spec (should @12ft-lbs.. Check service manual)

If it does not torque to spec its because its stripped. Throwing RTV, silicone, etc is a band-aid, plus will make servicing a PITA. The proper way is to re-tap/re thread with a proper tool. is similar to a tap but a little different, some even redo the seat (I.E. spark plugs)

If you have no experience or are not confident enough to try it, take it to a shop, it can be done within 40mins.

Might also find a fiber based washer, they compress sufficiently to fill some of gap on uneven surfaces.

Thanks guys! I'll take it to a shop and have them rethread it along with a new crush washer. It's probably stripped because when i was changing the tranny fluid i torqued it pretty hard then it broke loose.

It is pretty darn tight. Torqued down to spec or maybe a little tighter and it's a brand new crush washer.
