      Comments about Bars Leak Transmission Stop Leak (11 oz.):

      My 1999 lincoln continental was leaking quite a bit, last year, from the gasket where it attatches to the engine. I can't say exactlly how much, at this point, I forget, but I can tell you I cried as many tears. This product is still working more than a year later. It has contrubuted to my abillity to get to work, and (afford) to go to school, so well worth it.

        Comments about Bars Leak Transmission Stop Leak (11 oz.):

        Transmission lube leak. I think it originates as the driver's side driveshat as it enters the automatic transmission. There is a seal there.
        This has been going on for about 2 yrs. Obviously it's not a large leak but it shows up on my driveway pavers.
        Used it Jan 2013 at 94,800 miles.
        It is now May 2014 at 98,200 miles and the leak has returned but to a lesser amount.
        I only used 4.5 oz of my 4 Qt transmission.
        Now I am wondering wether I can add some more to reduce the leak, without change the transmn. fluid, Will look into that befpre I try it.
        No difference with my transmission just slowed down the leak. Which a lot cheaper than replacing the transmission seal!

            Hi Elk173, I'm happy to help you! Add entire bottle of Stop Leak to transmission to restore fluid level. Do not overfill. Leaks usually stop in 200 miles or 3 days of driving. If leak continues, second application may be required or mechanical attention is needed.

          If my transmission fluid was low, do I need to add transmission fluid after I add the stop leak? And do I do this right away or wait a while? Thanks!
