700R4 Question

Need some help with a tranny leak on my 1984 Corvette(93,000 miles). I resealed the pan and replaced the bushing on the linkage shaft. When I drive the car it doesnt leak at all. After I park the car and it sits for a couple days it will leak approximatley 1 pint before it stops. Any Ideas?

Thanks, Bill

Due to the amount that you specified, I would say that you should check the 2 transmission lines on the passenger side of the tranny and/or it could be possible that the seal for the torque convertor is leaking when cold.

Where is it landing when it leaks?

looks like left side of the trans, linkage side. leaves a nice L shape in my garage. How can I tell if it's the front pump seal?

If it is coming out of the front of the trans, it may simply be a weak front seal. If the spring tension gets weak, it will allow gravity to push the fluid out that sits above the centerline of the converter. It could also be one of 7 or 8 places on the outside of the trans. Look closely to see where it may be coming from before swapping out parts.

Remove the tin flexplate cover and look inside. If it is wet in here, it could be the pump seal, pump bolt o rings, or the pump outer o ring

If i pull the trans should I just get an overhaul? car runs very well but has 93,000 miles on it. It still has all the original exhaust.

That is a good question. Some would say "if it aint broke, don't fix it. I would rebuild it if it were mine. In my case though, I rebuild my own. Let your wallet be your guide.
