J.R. Posted September 9, 2013 Report Posted September 9, 2013 1950 Chrysler Windsor, 251, M6.... When I got the car the trans was empty and it shifted like it! I got my hands on about 3 gallons of the correct 10 WT oil for the trans, topped it off and went for a ride. It drove and shifted great then I parked it and came back outside about an hour later and there was a pool under the trans. I found a major leak at the solenoid and governor (gaskets were shot), I cleaned them and installed a new O ring on each to seal them up, it worked great and once again I took it for a drive. It shifted awesome and then I shut off the car and looked underneath... The second I turned the car off it started pouring 10wt out of the little drain I guess in the bottom of the bellhousing. First leak... Fixed... O rings (size -214) installed in place of gaskets.. This pic is before I pressure washed the underside of the car but you can see the little square in the circle at the bottom of the bell... So I am guessing I need to pull the trans to replace the gasket/seal that is leaking? I am still waiting on my shop manual to get here so until them I am at your mercy! Quote
De Soto Frank Posted September 9, 2013 Report Posted September 9, 2013 J.R. - Thanks for id'ing the subject vehicle right at the top of your Post! OK, transmission is mostly a four-speed "sliding-gear" transmission, upgraded with some auto-matic shifting voo-doo. Up front, there are no seals, per se; there is a gasket on the "throw-out bearing support" ( flange with long neck that bolts to the front of the tranny case ), but there is no seal on the input shaft bearing. Any oil that sneaks-past the bearing is caught by the T-O Bearing support, and returned to thetranny case via a drain. The main part of the tranny case is not under pressure, aside from that created by heat / expansion of the oil when hot. This is vented / relieved through the input shaft bearing & T-O beairng support. I think you might be overfilling the tranny... in your first photo, there are three square-head pipe-plugs, alomst in vertical alignment. The bottom plug is the drain plug. the middle plug ( just in front of the governor) is the filler plug (fill with #10-W oil until it just runs-out of the opening). The upper plug is an access plug for the shifter fork lock screw. Suggest you put a pan under the tranny, and pull the middle plug: if fluid runs-out, let it drain until it stops, then replace the plug. Now the tranny is filled to the correct level. If the transmission is over-filled, it will leak oil out through the input shaft bearing / throw-out bearing support, and drip out of the bell-housing. Let us know what you find... 1 Quote
Tom Skinner Posted September 9, 2013 Report Posted September 9, 2013 (edited) JR, If I remember correctly the Tranny takes @ 3 pints of 10wt any more than that and it will pour out of there. Rear seal usually goes first - easy to get to - pull shaft and e Brake Drum and replace. Its around $25. Tom Edited September 9, 2013 by Tom Skinner Quote
J.R. Posted September 10, 2013 Author Report Posted September 10, 2013 HA, yeah I over filled the hell out of it by about this much..... Next up I'm going to do the rear seal and the U-joints. Quote
Dodgeb4ya Posted September 10, 2013 Report Posted September 10, 2013 (edited) Yup might end up with a fluid drive clutch! Edited September 10, 2013 by Dodgeb4ya Quote
J.R. Posted September 10, 2013 Author Report Posted September 10, 2013 I pulled that center plug, let it drain to it's level, and took it for a drive with a few burnouts in between, no problems at all! Thanks guys!!! Quote
Dodgeb4ya Posted September 10, 2013 Report Posted September 10, 2013 A burn out in a fluid drive car? Thats amazing! Quote
J.R. Posted September 10, 2013 Author Report Posted September 10, 2013 Actually it does really good burnouts, one tire fire but still a burnout is a burnout. Quote
