'82 Airstream MH Transmission Leaking

[Greg Stinnett]

After my 1982 280 has been setting for several weeks it throws out about a pint of transmission fluid from around the dip stick tube after starting, Has anyone else had this problem?

I haven't had that problem but it almost sounds like its over filled with transmission fluid.

There's an '82 345 sitting in our shop right now with a puddle on the floor near where the dipstick tube is located. Probably a new O ring will stop the problem. It really is a 30 cent fix.

Not a known problem. Does yours have a trans cooler, could a line be plugged?

Yup, I think Terry nailed it.

Hi Terry and Marie!

Sounds like the torque converter is draining back into the pan when it sits for a period of time causing the pan to overfill. This could make it burp ATF up and out the dipstick fill tube, or it could be burping out the trans vent tube.

Thanks for all the information, it is greatly appreciated.

I wish it was just over serviced, so far I have drained and serviced the transmission and replace the o-ring on fill tube. The system does have an oil cooler but I don't know how that ties in to throwing out fluid.

It sounds like the torque converter might be the problem.

What would be the fix if it is the torque converter?

If that is what it is, the fix is generally a new converter and front pump.
Then you get into the "might-as-wells". Since the transmission is out and on the bench, you might as well rebuild the unit, as well as check the U joints and center support bearing. While you have it apart is the time for this.

With out looking at a book I can't say for sure where it is at but I think there will be a check valve or ball either in the trans oil pump or valve body that is sticking and allowing the converter to drain when it sit for a period of time.If it is (the check valve) in the oil pump the trans will have to come out. If it is in the valve body you might get away with just pulling the pan and cleaning/replacing the check valve.
