Just be sure the flex line is rated for carrying hot oil somewhere in the 250 degree range, as trans fluid can get pretty hot on a hard pull.

Anywhere your steel line could rub on something, split a piece of rubber line and wrap your steel line with it, then use a zip tie to keep it there. Or if it's a sheetmetal edge, put the rubber hose over the sheet metal. | | | | | Joined: Jun 2005 Posts: 1,001 'Bolter | | 'Bolter Joined: Jun 2005 Posts: 1,001 | homer52, what size trans cooler are you using, 18"?
I'm needing to put one in my 41 3/4ton, 350/700r4, and don't know how to size one. I will be using it as a "truck"; carrying at least one ton.

I use the biggest one that will fit the space I have available. On some really hard-working rigs like a vehicle that will tow a big camping trailer often, I have used an entire air conditioner condenser as a trans cooler, but that's probably a little overkill.

The coolers in the rads are fine for street use in cooler climates. For those planning on towing or heavier usage or are in a hot climate, you're better off with an auxiliary cooler. | | | | | Joined: Jun 2005 Posts: 1,001 'Bolter | | 'Bolter Joined: Jun 2005 Posts: 1,001 | I plan on using my original radiator. So whatever cooler I install will be the only one. Just want to make sure it will be sufficient.
