I went back and found the thread about the install of your trans cooler but what brand, model number is it? What other parts did you need for your install?
I used the smaller of the two because it is installed after my OEM one and I felt there was no need for the larger one, plus fitment issues as well....
No problem..... Also use transmission line or fuel injection hose to install, USE the SPECIAL fuel line hose clamps and the adapters for the cooler I had to order online, i could not find them locally..
