Yeah, I can accept that viewpoint. I work for Parker in hydraulics and we produce a very good thermal bypass valve used by Deere, CNH and other large OEMs on their hydraulic fan drive systems on AG machines costing well over $500,000. So my bias is based on that application versus the tens of thousands more everyday vehicle application.

Like you, in the winter I can wait a minute after starting the pickup before putting it in gear to go. Reading up on the 8HP-70 trans I was kind of surprised that some report it running hot commonly. But also, ZF builds a better trans than the 545RFE. So maybe I'm thinking too deep about the application. I'll have the trans cooler from my Dakota so I'll plan to mount it in the 56 and make sure I have the option if needed.
