RE: [Chrysler300] 1955 Powerflite Leaking

["'Jack Boyle' jackcboyle@xxxxxxxxx [Chrysler300]" <Chrysler300-noreply@xxxxxxxxxxxxxxx>]

Same problem, same diagnosis, same puddle

 

The torque converter seal leaks as the converter bleeds down into the pan
and over fills. The side seals above the normal fill level of the pan were
never designed to hold when submerged in fluid for weeks or months at a
time.

 

I have to add a quart in April after storage and never again for the whole
summer because driving it keeps the converter pumped up. I drove my car over
3000 miles last year, it used none all summer.

 

It's on my list to fix when the car undergoes a partial restoration as soon
as my Goers order comes in.

I spent way too much time and money on the tranny in our '55 C-300 and the
leakage problem was not resolved until an internal seal and parts were
replaced at the front end of the tranny to prevent drainage of the torque
converter into the body of the tranny.  The seal around the selector cable
seemed unable to control this hydrostatic pressure.  Heat-shrink tubing
around the shift cable (if cracked open and leaking) and a good new seal,
properly installed where the shift cable connects to the tranny are
important elements of the fix.

 

Sorry, I can't provide more detail.  There are more knowledgeable PowerFlite
experts than the shop(s) I used.  I recommend R&R the tranny and send it to
someone that knows how to do it right the first time.

NAPA # for that seal is/was 49482

At least it is in my 1985 cross reference book

Good Luck!

Hi All -

I have a nasty leak in a 1955 Powerflite. It seems to be coming from the
lever area. My theory is that it's the manual valve lever shaft oil seal,
which is part no. 1408353. . 

Does anyone have a NAPA (or other) part number for that seal ?

Also, the book mentions that a tool, C-3277, is used to install the seal.
Does anyone know where I can get this tool, or does anyone know a workaround
in case this tool is not available ?

Ron
