    So I posted last year about transmission fluid leaking from the output shaft seal of my 2007 prerunner. I replaced the seal myself and immediately after that had an appointment to have the dealer check and top off the transmission. After I replaced the seal and drove to the dealer I didn't notice any leaks. I believe they added 2 quarts, I picked it up and a few days later noticed it was leaking again. Just a very slow leak, same as before I replaced the seal the first time.

    I thought I had read something here saying if you replaced the seal and it still leaks could be u-joints? Had the warranty extension work done and they replaced 2 bad u joints still leaking?

    So at this point I'm wondering what people's opinions are on it, think I may have put the seal on wrong? I followed the instructions on this site to a T and it was definitely fully seated. Or another obvious issue causing it to still leak despite a new seal?

    A couple other questions.. IS THERE A WARNING LIGHT IF THE TRANSMISSION IS RUNNING LOW ON FLUID? cant find a clear answer. Wish it had a dipstick and I could check it myself lol. And it has been driven maybe 3k miles since topped off, and it seems to be a slow leak, how much fluid do you think I've lost? Debating on just adding a quart or half quart of fluid..


    Thanks for any help!

    Seals sometimes can be pretty fragile. Bump them the wrong way installing them and they leak. You could take it to the dealer and have them change the seal that way if it leaks you can take it back and have it fixed for free. Or you could buy a new seal and try again and learn how to check the fluid level yourself. There is a write up on here about changing your transmission fluid that has a procedure to check the fluid level. As far as I know there is no light or indicator if your tranny fluid is low so be careful not to run it low and burn it up.

    So based off what I'm describing think it's just the seal was not installed properly? I wasnt sure if there was an issue that would still cause it to leak even after a properly installed new seal.
