I replaced all the parts that were leak spots as previously posted. I put everything back together & filled the trans
back up with proper 'TYPE F' ATF. I ran it in neutral, got it up to temperature, cycled through the gears, checked the level... rinse, lather, repeat... for about an hour 'til I got the level right/stable. Shut'er down & waited... It's been 2 weeks... no leaks anywhere, no fluid in the vent tube extension. (I had filled six 1-quart bottles with what came out of the trans
, when I pulled the pan off/while I was waiting for parts.) SO - only a couple quarts were left in the lower half of the converter. I'm thinking maybe the trans
had the wrong type of fluid in it from the P.O.... Why? because last year I had a problem with my power steering leaking like a sieve too - especially once the fluid got hot. Even the return lines would leak at the gear clamp connections (low pressure!) The system had clear (non-ATF) fluid in it & it needs ATF... The P.S. pump was pooched & screamed like a banshee! Once I flushed-out the system & replaced the pump/re-filled with proper ATF, no more leaks! ... Back to the trans
... I was fully expecting to see SOME fluid in my overflow tube extension after a few days - but still dry after 2 weeks. We haven't hit really cold temps yet (that's when it was real bad last year), but even so - after a few days - no matter what, there would always be some. This leads me to believe that the trans
also had the wrong fluid in it & because it did not have the right properties, it was able to leak by the anti-drain back check valve. Now I'm wishing I woulda got that last 2 quarts out. At this point it's not leaking, so I'm happy. At the very least; it's a plausible theory that fits the facts...
