Correct me if I am wrong but the transmission fluid Exits the transmission
through the *inside* line and Enters the radiator through the *bottom*
hole. The fluid then Exits the radiator through the *top* hole (and flows
through an auxiliary filter I added) and then through an external cooler
that I added) and Enters or returns to the transmission via the *outside*
trans hole.

A. Is this the correct route?
B. Is there a more effective location for my add-on filter and cooler?
C. I have a temp sensor in the trans pan and was going to put another in
a line at the trans...would it be better at the 'out' or the 'in' to watch
fluid temps

Thanks all.

Hi Mike

Your hookup sounds fine.

I have a sensor in the pan and at one time I had one on the return output line. I later decided that the sensor on the line didn’t really tell me anything so I took it off.
The one on the pan works fine for me and even when pulling a toad and going uphill it doesn’t get very hot.

Gentlemen
Many thanks...while I frequently say, " Luckily, the mind is the first to
go...", it isn't all that convenient !

Tks

Me too on the former cooler line gauge. I was also reassured by the
Chevrolet P30 Chassis Manual's excellent writeup on ATF, coolers, etc.,
bases all of its ATF life projections on PAN temperature.
