Thanks very much everyone for the replies. Sorry it's taken me so long to get back to this thread... Got busy on some other projects, and just now
getting back to this....
Scott: normally the coach reads below 200 trans temp on my gauge, but this trip I saw 2 hills where the temp climbed up to 220-230 momentarily before
coming back down after I eased out of the throttle.
Matt: I took another look and I see what you are saying about the factory cooler being on the cold side... I had it wrong in my head as well for some
reason...
So I'm sold on running the primary cooler then on to the existing aux cooler and back to the trans routing, which means I need to make new lines...
The existing lines appear to be 5/16, but from what I read, a 3/8" line is better in this application, and since I'm redoing most of the line, I might
was well do it all in 3/8....
Was thinking of going with Nicopp tubing as it is corrosion resistant, and much easier to work with then stainless.
However, I'm not sure what fitting size is needed on either the trans or the factory cooler ends of the line... Would flaring the tubing with the
appropriate size fitting the same way you would a brake line be the best method of terminating the 3/8" hard lines? Or would some sort of compression
fitting be best? Either way, does anyone know the appropriate fitting sizes on the trans and factory coolers as well as what kind flare or flare
fitting would be needed?
