Joe Flanagan Posted May 14, 2015 Report Posted May 14, 2015 Last time I tried to check the fluid level in my overdrive transmission, the front section was full to way above the the drain plug and the rear section just needed a little top-off. I understand the oil is shared between the two halves but I can't understand why the front would be overfull. When I pulled the plug, the oil poured out and I had a struggle to get the plug back in. The rear half, as I said, was just a little bit below the drain plug hole. I wouldn't bother except that the transmission has a couple of steady drips and I want to make sure I haven't lost too much. What am I missing? Quote
plyroadking Posted May 14, 2015 Report Posted May 14, 2015 I had a friend that had the same problem, the person that put it together did not remove the gasket material that blocks the galley between the center case and rear case. He ran a rubber hose from the front fill plug to the rear fill plug to get by until I had time to pull it and replace the gaskethe for him. Quote
Joe Flanagan Posted May 15, 2015 Author Report Posted May 15, 2015 What exactly was the purpose of the rubber hose? Quote
Jerry Roberts Posted May 15, 2015 Report Posted May 15, 2015 It sounds like the purpose was to allow the oil to transfer from one part of the transmission to the other part of the transmission . It was blocked by the new gasket . Quote
plyroadking Posted May 15, 2015 Report Posted May 15, 2015 Jerry is correct, somehow the fluid would leave the od section and collect in the trans section. Maybe has something to do with the od section not having its own vent to the atmosphere. As everything expands when it gets hot the fluid works through to the vented trannys case. His theory was to let the fluid return to the od case with the hose, but it probably just used the hose as an air vent rater than pressurizing the od case and forcing the fluid to the trans case Quote
Joe Flanagan Posted May 15, 2015 Author Report Posted May 15, 2015 So, am I at risk of damaging the transmission by running it like this? I bought it from Neil Riddle. It came out of a 52 Plymouth and worked when it was removed from that car. I don't know if it's ever been apart. Quote
Jim Yergin Posted May 15, 2015 Report Posted May 15, 2015 Joe, Would it be worth a call to Neil Riddle? Or maybe George Asche? Jim Yergin Quote
Joe Flanagan Posted May 15, 2015 Author Report Posted May 15, 2015 Probably. Do you have the same issue with yours? Quote
Jim Yergin Posted May 16, 2015 Report Posted May 16, 2015 Joe, I no longer have my Plymouth but before I sold it I had a leak I could never find and was constantly refilling both sections. Jim Quote
