Transmission fluid leak during storage

[A83]

Second year in a row I noticed red transmission fluid on the garage floor underneath my 83 _ fairly good amount plus it happened once during the summer. Any insights on this?

Thanks

Need a bit more info. Front, rear, middle, under yoke, leaking down pan or at the cooling line connections.. The most common places to leak are the pan, speedo cable seal and rear yoke. Pray it's one of them. Get it up in the air and look it over. Report back, as it's tough to diagnose without much info. Bob

Here is what happens,because we don't drive them daily or store them all winter the fluid in the torque converter drains back into the case raising the fluid level in the unit . You can check this by checking the fluid level after the car has cooled off from a drive -not running,take a scribe and mark the level, wait a few days and check level again if it shows above your scribe mark you have drainback. When the case fills the fluid will find its way out the least tight sealing surface manual shaft,case connector, pan gasket, speedometer o ring and or seal , throttle pressure cable are the most common spots. If you or a buddy have a hoist put it up and look for the tell tale drips. Lou Cote

Thanks I did notice that the level on the stick was high - that makes sense. Appreciate it.

Happened to me once, leaked a quart or so after sitting for about a year on a level garage floor... filled it and drove it, hasn't leaked since. Beats me.

The leak was in the rear of the transmission put a new seal in will see what happens

Thank you everyone

Was this a leaky rear seal? How was the fit of the yoke in the rear bushing? There should be almost no up or down movement of the yoke. The rear bushings do wear. If you have the 4 speed automatic, you can use the up graded rear bushing that is bronze it has dimples in it that allow for more lubrication. Lou Cote
