Transmission oil Leaking after freeze
Hi,
I have an 08' 6.4 with about 125k miles on it. Never had any issues with the transmission until recently. About a month ago after a freeze I noticed trans oil puddled under the trans, and all over the trans pan. I cleaned it off, checked the transmission oil level and ran the truck but it wouldn't leak anymore. Since then I have been using the truck every day for over a month with no leaks ( I check every morning and evening). Then this morning I noticed the same issue- trans fluid all over the trans pan and puddled under it. This morning was also the only day since the last time I saw trans fluid that it froze overnight. I am thinking that the seal on the trans pan shrinks when it freezes and allows the fluid to leak until it warms up.??? Could this be the issue? Has anyone had a similar problem< or does anyone know if replacing the pan seal would help? Thanks in advance

You can try to retorque the pan bolts a little. Very little! See if that helps.
A good surgical cleaning is necessary to find the point of the source leak.
If you haven't had the trans serviced, probably a good time for filter/gasket change and a flush.

Thanks Diesel Denny! I will try tightening the bolts and see if that helps. I believe we serviced the trans around 100k but I will check and see. If we have not serviced it, is this something that is somewhat easy to do? Meaning could I do it myself? I do basic work on our vehicles oil changes, brakes, ect. It is a fleet vehicle and it really sets us back if it has to go to the shop, so I was hoping it would be something I could do on Saturday. Thanks again

Agree 100% with Denny on the OEM materials. You have a good theory there with the gasket. I've got 121k on my 2010. Just had the complete trans-flush/filter done at Ford. Haven't had any issues with trans fluid leaks yet. I'm down in Houston TX though...don't see many temp fluctuations into the low 30s.
