Every spring,after lowering from jack stands, the transmission in my 1928 phaeton is out of oil and the differential is over full. I use 600 wt oil. The floor under the transmission only shows minor drips. Has anyone used corn head grease or some additive to help keep oil in the transmission, I would rather not pull the trasnmission if possible.

Is there a baffle on the rear trans bearing? You might want to check the levels after each longer drive.

there is a seal in the torque tube that should limit transmission oil from migrating down the driveshaft
When the car is jacked up is it level?

Remember 'You can pay me now or you can pay me later' ?

To avoid pulling the tranny, keep doing what you are doing on a yearly basis.

Keep in mind an over full rear end might result in the fluid migrating down the axles and out on to your rear brakes.

Oil can likely migrate that way but the sump in the transmission is low enough that some should still be in there.

Bringing a stored car back to road duty should always include fluid level checks anyway. This can be overlooked but the suspension brought to full extension for storage does allow the differential to be as low as the spring and shackles will allow. The torque tube wouldn't normally hang down that way.

If the garage doesn't allow much movement to prevent flat spots then putting it up on stands would be the only way to do that,

I am a little confused about how the car is put on jack stands. Are the stands under the axles or the frame rails? I don't see how putting the jack stand under the axles would change the angle of the torque tube.

Pulling the transmission is not that hard. They are simple to rebuild. Just don't drop it on your front tooth. I am still dealing with that after 60 years.

Jack stands are under axles.

Is the front really raised up? The stock Model A transmission has no seals, just a oil slinger. It only takes a 1.5 pints to fill the transmission, this isn't even up to the bearing to leak past if the vehicle is level. Are you checking the fluid level before the vehicle is put away? I have a feeling it is empty when you park it.

Driving's a blast, a blast from the past.
