I recently noticed a small amount of transmission fluid under my car after i had started it in my garage. It's been below 0 degrees here and i wanted to run the car to make sure the battery didn't die, and to get the fluids runnng in the vehicle.
Someone has mentioned that the rear transmission seal may have shrunk due to the cold and once I drive the car and get the fluid warm again it should seal itself.

Any suggestions?

I suppose it's possible and being a 98 I'm sure they are a little stiff and dried out too. Then again GM designed the car to be driven in all weather conditions…

I wouldn't worry about it until you start driving it again regularly, then keep an eye on it.

FWIW And this is just my opinion so take it for what it’s worth (not much at Starbucks!), it isn’t a good idea to start the car while it’s in storage. The oil temp needs to get up above 212 and maintain that temp for some time just to burn off the induced moisture of it warming up. Then as it cools, it will condense moisture out of surrounding air.... Metal + water = corrosion

The issue with starting it and running it for a short period every so often is the water that is by product of the combustion process. It leaves water in the oil and the exhaust system.... that leads to corrosion. Even if you let it run 20 minutes and the engine is hot.

Hope that helps…

it could be just a small crack in one of the rubber tranny lines. i have had a problem with them spliting on me a lot it dosent help that i have a custom build tranny and a lot of mods so its under a lot more pressure. if you can lift up the front of you car and see if you can feel any spits or let you car run for a bit then get underneith it and see if you can feel where its coming from.

Thanks, it only does it when I start the car, and being the middle of winter, when I get it out I'll check all the rubber lines.

tstar, thanks for the advice, and I'll wait until I can drive it for a while before I start it up again. I only have 5,000 miles on it , (bought in Sept. 06') and I don't need any corrosion issues

5k on a 98?????? Holy heck!!!! Good find!

And that's even more fuel for the dried out seal theory, she's been siting for a long time! I'd run her on the highway for a good two hours, run the AC too. Then go over the car with a magnifying glass.

BTW is it an auto or stick? I had assumed auto like 1niceC5 has, who BTW gave you some excellent advice!

Tim, it's an automatic. Came from Texas from a collector who obviously didn't drive it much. Engine compartment and underneath carriage look like it rolled out of showroom.
Thanks again for all the helpful advice!

Will post pictures as soon as it's out of storage
