ok i've got 4 early b body dodge 62-65, whats the deal with every one leaking AFT all over the place, never in my life have i ever had a mopar leak so much, when i park on a hill (my driveway) it gets even worse sometimes even my drip pan over flows. i need to fix all 4 cars, can someone point me in the right direction in where to start looking for the leak, it's not the dip stick tube, not the pan gaskets. is it the torque converter seal?
please help?

are they much different than late 60's on 727/904's? not too bad really if they're the same. remove the shifter linkage off the top and drop the pan. might as well do the filter while your in there. use a small punch to drive the seal up (don't score the shaft) and a socket to drive the new one in. you might want to drop the tail on the trans to get more room.
take it to the coin wash and spray the old crap off so you can see where it's leaking from

stupid thing won't upload the screen shot of the factory manual :angry1:


hey' just noticed your over in chatsworth, i'm over by balboa park

good luck

LOL! Was thinking the same thing! Yeah, had several auto cars that leaked at the shifter seal.....and the dip stick and the rear seal and the front seal and the..........
 
I changed my seal for the kickdown linkage in a matter in minutes ,but mine has cable shifter,just removed the linkage and picked out the old seal seal with the sharp part a test light.If this is the type of seal you have ,i can give you the part # for a new one ,the dealer still carry them.The same seal is used in the new Dodge trucks,linkage.
 
Suspects are the shift and park cable O-rings, the park lock housing to main housing gasket, the kickdown lever shaft seal (that's where my '62 leaks from once the torque converter drains down and brings the fluid level above that seal), the speedometer cable O-ring, and the shift and park cables themselves -- if they fall down out of their floorpan brackets and come to rest on the exhaust pipe, the outer casing burns off and you'll have a leak. No need to replace the costly cable -- fix it. Clean down the cable thoroughly with brake cleaner, cut a piece of fuel injection hose (marked SAE J30R9) 3 inches longer than the damaged portion of the jacket, slit the hose lengthwise (some "spiral" to the slit helps), coat the damaged area of the cable with Mopar RTV (don't substitute another brand unless you want to make a mess rather than a repair), place the slit hose over the area and twist/shift it a little to spread the RTV, then apply hose clamps at 1½" intervals, just enough to hold the hose firmly, but not so tightly as to squeeze the cable, which would cause it to bind.

Stubborn pan gasket leaks are easy to fix. Forget either type of floppy gasket (cork composite or rubber). Forget trying to seal a warped old pan. A nice new heavy-duty pan with unwarped rails can be had from the dealer under p/n 52118 779AB (for A904 -- if you have a 727, it's 5211 8780AD), and it even includes a doughnut magnet to catch metallic shavings. While you are at the Chrysler dealer, get the really nice double-seal, reusable rigid pan gasket p/n 4295 875AC for 904, or 2464 324AB for 727. Use new correct 5/16"-18 × 5/8" bolts with captive washer, p/n 4723 548. The pan will never leak again.

See here for info on retrofitting an in-pan filter to the '62 and '63 cars with the external trans fluid filter (no longer available and a PITA to deal with).
 
whatever it ends up being, if your not up to doing it yourself, try Leon's on Reseda s/o Saticoy. great people that won't rip you off
 
mine leaks when i park on an incline ( nose up-hill ) . it drips from the front yoke, was told some of them had casting flaws and had small hole at the end of the splined shaft. have yet to remove the driveshaft to inspect / repair yet ! ... but maybe an idea for your problems ??
 
Mine leaks at the dipstick tube, the original style o-ring just would not seal. I swapped it for an aftermarket one from Mancini and cut the leak to about 1/4 of what it used to be.
 
all mine were leaking from the shifter CABLE and not the seal.
disconnect it from the push button side abnd slide some long pieces of shrink tubing over it and double it up. mine never leaked again.fluid runs inside the cable and if theres a crack or burn in the cable you'll see it
in the cable.
 
Extreme Fix

Mine was leaking so bad in my '63 Fury that I had a concrete mixing tub to catch it all. Solution, I ordered all new parts from Cope Racing Transmission. All the seals, bushings, servo seals, steels, clutches, bands, bolt in sprag and all. Problem solved and the tranny is good to 550 HP. Cost $850.00 and my labor but it doesn't leak!:hello2:
