Installed the aux trans cooler that I posted the diagrams too.... some
time ago. Have not installed the hoses yet.
I want to install the aux trans cooler in series with the OEM trans
cooler that's part of the radiator. Instructions show and other
references say that on a 7004R the top trans cooler line at the
radiator is the return line.
So I crank truck up and let it run a while. I touch both the top trans
cooler line and the bottom trans cooler line (at the radiator)to see
which one is hotter. My assumption is that the return cooler line
would be cooler, since the fluid has been cooled? Truck just idled
for a while...
ON my truck the top cooler hose at the radiator is hotter than the
bottom line, which does not seem right to me? I'm wondering if the
cooling lines were swapped at the trans when trans last worked on?
Can anyone tell me which fitting on the trans corresponds with the top
or lower fitting on the trans cooler...at the radiator. 1992 K1500
7004R trans....350 engine.
I know I can disconnect the hard line at the radiator to see which way
the fluid is flowing but would prefer not to do that..
