I don't mean to ask what port is the in- or outlet for the radiator, but what way goes the ATF inside? does it go from the pan through the valve-body to the converter and finally to the cooler or does it take another way? Can someone guide me as to the correct connections for my TH400 Auto Tranny to the Radiator on my 69 Coupe BB? I am thinking the it should be as follows: FROM TRANNY TO RADIATOR: Outgoing hot fluid from UPPER Tranny Outlet Connection is routed on right outboard side of BB engine and turns out and up. The PR valve limits or regulates pressures to the common 50-250 psi range seen in transmissions. Your gears and hard parts will thank you for not running Type F. Direct clutch plates burned. Like the 4L80E, there are also differences between the 4L85E and the TH400 transmission. Using the pan bolt. Type F has better anti-foaming agents than the Dexron specs. Inner cable is molded with appropriate trans fluid levels. The following charts provide the mainline pressure readings for all of the various TCI® transmission models. If the fluid is adequate, then inspect the release switch. 1971-Chevelle. Block was decked to 8. In contrast to the parallel flow heat exchanger, the counter flow heat exchanger can have the hottest cold-fluid temperature greater than the coldest hot-fluid temperatue. Blood flow is the continuous running of blood through vessels in the cardiovascular system (the mammalian cardiovascular system is shown in ). Handle it with care, and store it . 1) Start the engine and allow it to warm up to normal operating temperature and then shut it off. The top transmission line runs to the top of the radiator.
