65 Dart Wagon Conversion to a Sedan Delivery
I needed to call the people who rebuilt my 42RH - Proformance Transmissions (they are a companion business to Dynamic converters). I had a question about fluid type. The 93 shop manual I’m referring to for the 42RH specifies a fluid type no longer sold. He said use the Mopar ATF+4 or equivalent.
I mentioned I would be using an external cooler in addition to the stock radiator cooler. He said great idea! He said route the pump side line first to the radiator then to the external cooler then back to the transmission to get the greatest cooling benefit. Hmmm OK. I was going to do it just the opposite.
I asked about the benefit of an external transmission filter. He said another great idea for transmission longevity. The internal filter can’t catch everything - check the bottom of the pan! So i decided to add one since it can’t hurt. I found a Perma-Cool 10678 kit
Thats uses the Fram PH8A or PH43 or equivalent filter and is the same routing as recommended by Perma-Cool and Shawn at ProFormance Transmissions
And I will have to wait till I install the
engine/transmission/K Frame as a unit to find the best location for this.
