My '62 will puck AT fluid after it sits for awhile. I've replaced all the seals and baseplate gasket. It seems to come from the breather...

Re: Pucking Powerglide
Geoffrey:
The fill tube is taller on PGs after 56. It is common for 56 PGs to puke out the top of the tube after they sit for a while.Comment

Re: Pucking Powerglide
I also had a '56 with pucking powerglide. Removed it from the car and had it rebuild three time and ended up with the same problem. Got sick and tired of the problem so I replaced it with a four speed. Anybody want's to buy a used '56 powerglide??

Re: Pucking Powerglide
A PG that throws up is caused by AIR being sucked in to the oil pick up at the filter. On the right side ( passenger) pull the filler tube plate, remove the two screws holding the filter and replace the filter seal. The screws can get loose or the seal is hard( gets harder when COLD) or not seated . Make sure the vent is open at the top of the PG.
Oil leaking usably is the filler tube seal not sealing which is better to add a sealant also when you replace the seal.
If the PG slips on right turns the oil is low or the filter is getting clogged.
AND if the PG bangs in to drive the drive band is out of adjustment OR PG's having a vacuum line is leaking air or the modulate is bad. Just a few things to consider .Comment

Try Shutting it off in Neutral
Lenn, I had this problem on our 53 and 54. Both PG were rebuilt and they still did it. Someone told me to turn the car off with the tranny in neutral. Since I have done this it has not happened. Eric #3182Comment

Yes. Puke. I don't know how the "c" got in there.Comment

Re: Try Shutting it off in Neutral
Eric! It could have been me.Two things,
1. leaving it in drive or neutral causes the engine crank (if the rear bearing trust area is worn ) to keep the crank forward causing the the engine rear main seal to sit at a different location and the PG seal also.
2. The PG check valve is left closed holding pressure on the Torque Convertor fluid . ( no run back).Comment

Re: Try Shutting it off in Neutral
The filter is not like a C2's ( a trow away) It's completely made of steel having a fine screen which can be cleaned and reinstalled. You may be able to re-use the seal.
If not that's a problem you may have to call the person in the restorer ,a supplier for PG parts. The side gasket can be re-used or you can easily make one. You will lose only about a quart of fluidComment

Re: Pucking Powerglide
Some may have mentioned this already but hear goes...The torque converter holds several quarts of fluid. As the car sits, it leaks down and over fills the transmission pan resulting in the fluid coming out all sorts of places, especially around the filler neck tube. The longer it sits the more likely it will happen. Worn seals related to the torque converter will cause this or badly worn seal surfaces related to the converter or seals that were damaged on assembly, etc. I don't recall which ones because it has been a thousand years since I have had to deal with this. I am sure someone else can comment on this though. It is a seal problem though. TerryComment

Re: Pucking Powerglide
I believe there is also a large bushing that the converter rides on. If that is worn, it will contribute to the same problem. Just my two cents worth. If the transmission is taken apart, it needs to be inspected closely for slightly worn parts. Someone mentioned a check valve. I have not totally disassembled a PG but if it is partially responsible for holding back the fluid in the converter, that would be a source of back fill also. TerryComment
