'50 Ultramatic Trans Cooler Lines
Posted by Joe On 2024/1/23 21:25:27
Hey gang - 1950 Packard model 2302 w/ Ultramatic here, still running the stock setup for transmission fluid cooling (internal, bottom of the rad). I stumbled on the external trans cooler kit introduced in the Service Counselor No. 26, vol. 6, though most I've talked to about it steered me way from pursuing this kit. Instead, I've been driven toward simply installing an aftermarket cooler in front of the rad. Seems like a cheap, easy, and positive thing to do for the transmission, so I figured why not.
In reading the installation instructions for the external cooler, it mentions running the external cooler in circuit with the OE cooler. I figured I would try to run it this way first - I'm not having any issues with my current cooler leaking into the rad, and cutting it out of the circuit would be easy to do if needed in the future. I would expect you'd want the fluid to go through the internal cooler, then the external cooler, then return to the trans.
After perusing the forum, parts book, and Ultramatic service manual, I can't seem to find which line is the supply and which is the return. The picture is the view from above looking from driver's side fender. I recently departed from the OE lines recently due to some leaking, hence the rubber lines.
Feel free to set me straight if my thinking is off on the approach here. Thanks, everyone!
