I am guessing the pump isn't working on my 3 speed auto trans. I had problems with the trans when I bought the car. She slipped in all gears and when on jacks stands even in reverse she rolled forward.

1st thing I did was drain the fluid drop the pan and the valve body and inspect everything. When I go to fill the car back up running on jack stands she takes about 3 quarts and that is it. I am guessing the pan just fills up and that is it.

Also before I pulled the pan, while the car is on jack stands and in drive the wheels would barely move but if I pushed on the large diaphragm on the passenger side of trans the wheels would accelerate. I took that diaphragm apart and inspected and put it back together all looks good and clean.

I am clueless.

it might be less expensive to fit a good used trans they are out there.

not sure about your issues unless the trans you have is taken apart.
only taking 3 qts tells me the front pump isnt pumping, so the trans has to come out anyway.

Did you find any metal in the pan?

Fluid wasn't burnt but has a shimmer of metallic flake. Nothing big in the pan I have anther used trans but just making sure this one isn't repairable 1st without pulling trans.

pull it ,
and swap it out,
you can be running in about 10 hours
For the trans your installing replace the front pump O ring and the radial seal of the TC,
also put some vaseline into the bronze bush behind the radial seal,
Replace the TC bearings as well

Swapping trans as we speak. Might be a little longer than 10 hours. I got my 4 year old mechanic in training helping, mom's going to have my a$$ she is dirtier than I am. LOL.
