Re: Transmission cooler line replacement

[Matt Haas <mhaas@xxxxxxx>]

Roger,

Just make sure that you get hose made for transmission cooler lines and use 
good hose clamps (none of those crappy Tridon clamps) and you should be 
okay. Sticking the end of a wrench over the line will give you it's O/D 
(it's probably 5/16 inch). That's the I/D of the hose you need to buy. 
Also, you'll need to have a little bit of metal line to connect to the 
fittings in the tranny and radiator. If you buy two short sections of steel 
line and cut them in two parts, you'll have everything you need to connect 
to the tranny and cooler.

I'd suggest running it from the tranny to the frame sill (leave some slack 
to make up for engine movement), up along the frame sill and over to each 
cooler fitting. Make sure that you clamp it out of the way of hot and/or 
moving parts. You should be able to find suitable clamps at most auto parts 
stores. Also, if both cooler fittings are on the bottom of the radiator, 
you may want to use steel line from the driver's side fitting to the 
passenger side frame sill so you don't need to find a neat way of tying a 
rubber hose out of the way.
