Re: [Chrysler300] leaky transmission 62 sport

[2HsandaHeritage@xxxxxxxxxxx]

Hi John, 

  

Have you checked the O ring located where the shift cable attaches to the 727? 

I had a sever leakage problem there because someone had installed an incorrect sized O ring. 

I was able to find a correctly sized one here in Sacramento and that stopped the leak. 

As I recall, the O ring was in the 727 housing and not on the shift cable.

Billllll: 

I had the same problem on my ’62 Sport. It used to leak a river of trans 
fluid out and under the garage door for years. It was definitely leaking 
from the area of the shift cable. I recently took out the trans and had it 
rebuilt. When it came time to reattach the push button shift cable, I 
slipped a piece of good oil resistant tubing over the shift cable (maybe 
15-20 inches long) and clamped it right at the point where the cable 
attaches to the trans. I used one of those clamps that you have to use a 
ratcheting tool to crimp the clamp. This has solved this source of leakage 
positively. That is what I would suggest. 

Imperial Services used to source these cables but I have heard really bad 
stories of non- shipment of cables bought and paid for from them. I would 
NOT use them if I were you. 

However, I now have another bewildering source of trans fluid leakage. I 
fill the trans to the required level on the dip stick so it drives and 
shifts perfectly. I placed a large drip pan (approx. 3 x 5 feet by ¾ inch 
deep in size) under the engine/trans and filled the entire drip pan with oil 
dry to try to see where the leakage is coming from. Within a day or so, I 
sometimes see a small amount of trans fluid leakage (about 1 inch in 
diameter at most) under the drivers’ side rear of the trans pan. This 
doesn’t change for about 2 weeks. Still the same size oil spot. Then 
overnight (after a week or two of sitting) without starting the engine or 
even turning the engine over, I look under the car at the pan and the entire 
drip pan is filled to the brim with trans fluid. 

I cannot figure out why there is no leakage for two weeks and then overnight 
the drip pan is full. The only thing other Mopar friends can suggest is 
that the transmission vent on the tail shaft of the 727 trans is somehow 
plugged and the trans builds up pressure until it “Burps” out about a quart 
of fluid. The entire transmission case is dry as can be – no leakage from 
any of the lines to the radiator cooler. When it does leak, it just seems 
to seep out of the rear of the trans pan. 

I thought maybe it was coming out of the dip stick filler tube but that is 
all dry. I have not removed the filler tube to replace the “O” ring as yet 
nor have I investigated the transmission vent. 

On one occasion, I thought that perhaps the torque convertor drain plug had 
leaked. It had not leaked for a week or so but I did start the engine to 
check the trans fluid level. I thought that on starting the engine, perhaps 
the torque convertor drain plug had revolved around to a lower level and 
provided a leakage point but I checked the plug and it is tight with no 
leakage evident. 

Has anyone else had this problem? Any possible solutions to this puzzling 
problem?

my transmission dude tells me that the trans oil is coming out the shift 
cables...is that possible? 

if so, what is the solution? 

replacement cables? 

and from who? 

i will name my next child after who ever helps me with my leaky problem.
