Need advice on a storage problem

I have a power glide tranny. Over the winters since 1998 it has leaked 1 quart of tranny fluid every year. It is the only fluid this car leaks. I changed over to a neopreme gasket in 2005. It still leaks the same amount every year. Once the driving season starts it does not leak. This is a problem only over the winter storage season!

I know that when trannys sit over the winter the torque conveter leaks all its fluid back into the transmission causing it to be way overfull and then leak from every available oriface. Sometimes there are fixes for this and sometimes not I would talk to a good tranny shop and see what they say. But also the leak may not be the pan gasket it could be the dipstick o-ring or something even higher up on the case.

Good bet it's the shifter shaft seal...or the converter seal. That does the same thing on my TH400 when it sits for a time.

I had a similar problem with mine during the restoration, it would only happen after a week or so, turned out that once I pulled out the dipstick tube and applied a thin layer of RTV black around the o-ring and put it back in place. It has not leaked a drop since.

I normally have this happen, but this is the first year it hasn't luckily. I think i've got everything solved.

Don't worry, it's just mad at you for not being used, like a dog left home alone for too long.
