Hey 327, mabie ya got a bad sending unit,plug a manual gauge into the port and see what kind of pressure you got.

I agree had them go bad before.

jr's3800, The reason I am taking it in for service in the morning when I had a tranny flush a couple of weeks I have been noticing atf fluid under the car. It is not a bad leak just a little spot it leaves when it sit overnight. I asked the service advisor about the possibily they overfilled it during the flush. He said it is probably a loose connection that they forgot to tighten during the flush. I figured while it is up on the rack I would have them check the sensor inside the pan.

327 its not the pan sensor its the sensor by the oil filter.

A new sensor was installed in July. Maybe I got a bad one. Will have them check it in the morning.

jr's3800, The tranny flush was done without replacing the pan gasket and filter. It never showed any signs of leakage before I had the flush done. I am figuring it may be just a loose connection.

jr's3800, I keep my car garaged at night and on a level surface. I got the car from a Volvo dealership in Jul. They installed a new oil sending unit but who knows what brand. I will have them check it in the morning. Thanks.

Ok Don. Will post the findings tomorrow.

Jr, Well they found the cause of the leak. It was coming from the gasket around the pan. It looks like the previous owner never had the tranny serviced because there was a "paper" gasket on it. It was replaced with a rubber one. Also had a new filter put in too. One good thing I guess no large chunks were found. As for the oil sensor, it is a new one. He took it out cleaned the fitting and put it back in. So far no light coming on after eng start. Time will tell.

jr, Just got back from chow and so far no light coming on. The mech showed me the bottom of the pan which had a light coating of atf. he said they stopped using the cork gaskets years ago. Glad I went in and got it fixed.
