So I am in the middle of replacing my 65RFE with the 8HP70 and need some help with the TBV.
One of the threads I read about an 8 speed swap showed that they removed the entire thermostatic housing and tapped the two connections on the side of the transmission for the cooler lines. I don't really want to do that and I found some -8AN ORB to -6AN fittings that replace the quick disconnect fittings on the thermostatic housing, which is what I will use to connect to my factory 65RFE cooler lines. As for the coolant/heat-source connections, I never had any plans to hook that up so I will simply cap those coolant hose connections on the thermostatic housing.
As for the TBV, I have been reading about people bypassing the thermostat and using the RevMax kit. I don't think I would need the block off plate since I don't have coolant lines hooked up, but for the TBV, can I simply remove the brass-fitting/springs/guide-pin and simply reinstall the factory plastic cap, o-ring, and snap-ring? Or do I need something like the RevMax brass fitting to put in there? I am not sure if they simply recommend replacing the factory plastic cap with the brass cap or if it is different in any way (other than material)? With only the cap, o-ring, and snap-ring installed, I am not sure that the fluid would flow much to the cooler as it would take the path of least resistance, which I would think is the heating circuit (even though there is no heat input, the circuit is still maintained), and minimal flow from the cooling circuit. I have no desire to have the ~180F operating temperature and simply want full time transmission cooler flow.
