Re: [Chrysler300] Torque Converter Drainback / Leaky Tranny (Again)

[John Nowosacki <jsnowosacki@xxxxxxxxx>]

I had a somewhat crazy idea as to how to deal with this for my G.
I also took the car to my local tranny shop, but after 5 days there was
still no leak.
I know that over the course of a winter, almost a quart of fluid will leak
out as the TC drains back into the pan, so I did the following:
I warmed up the car and made sure the fluid level was at the right level
for the vehicle.
We then put the car up on the lift and let it sit for one day.  No leaks.
I then proceeded to add an 'extra' quart of tranny fluid thru the dipstick
tube, simulating a 'fast' TC drain back into the pan.
That increased the level enough so I could see that the fluid was coming
out around the kick down shaft as there isn't much of a seal there (at
least in my car).
Once that source was found, fluid was drained back to the correct level.
The bad news is that I have yet to drop the pan, valve body, etc. to
install some kind of bushing or seal around the shaft because it is
running well and I don't want to mess anything up, but I think it did
successfully reveal the source of the leak.
