the fittings on the trans are 1/4" npt. I'd go with -8an fittings and hose. You may have a problem if trying to keep the exchanger though. Those are -10 or -12an fittings and trying to match -8an hose to those sizes might be hard. You'll also need to cut the line off the front cooler from the exchanger and have a fitting pressed on. The other line off the cooler to the trans already has a -8an fitting that can be disconnected. 12ft. to 15ft. of hose should be enough

Well tell me this I have the hose that goes from the cool in front to trans it is leaking at the cooler I have heard that with my trans which is a stage 2 from Jeff garmon that I need to get rid of the stock style lines and go with the ss line setup because of the pressure I have had that tranny for over 2 years now and the leak that I have is just a little wet not pouring out or nothing like that do you think I can go with a new stock line and be ok or what? Thanks

the stock lines are fine for the psi Jeff sets VB's at. I would just replace it with a stock line, it would be a lot cheaper to do. A lot of times, when the lines get removed and replaced on the exchanger, the threads get boogered up because of being aluminum. Not much you can do there with a leak but, replace it or remove it. I'd look into removing the exchanger. Jeff can tell you why it's not a good thing to have when you spend 3K or more on your trans.

Well the thing with the exchanger is like today its in the low 30s and gets colder than that sometimes down near 0 but not all the time where I live will that hurt anything if I get rid of it. I assume that it helps bring the oil temp up. I just dont no the pros and cons of it is the thing.
