Re: Transmission cooler line replacement

A: Hoses have changed formulas over the years and you MUST use transmission 
hose now. Not so much for the pressure, but the fact modern "rubber" hoses 
can't withstand oil like they used to. There is also barbed fitting you can 
screw into each end where the lines used to be and clamp the hoses down so 
they don't come off. The ones on my Jeep were just slid over the lines and 
double clamped, but they kept coming off at the worst times (and I wasn't 
even 4 wheeling the truck at all!)

There should be about 7 lbs. of pressure on the tranny cooling lines. On my 
more recent restorations, I have used steel and double flared the ends. 
However, I have a Jeep with an automatic tranny that I have used for 25 
years with rubber lines. Just keep them strapped up and away from heat. All 
you have to do is slip the rubber over a stub of steel, and clamp it down 
with a worm drive clamp. If the radiator has top and bottom cooler fittings, 
use the top one to receive the fluid from the tranny and the bottom one for 
the return. I put a piece of hose on both the lines from the tranny and put 
them in coffee cans. Then started the vehicle, put it in gear, and checked 
the cans for which one contained oil, hence it was the line to the radiator.
Happy motoring.
