hey guys, what are the type and size of fittings coming out of the tranny? i want to replace the lines with 1/2" all the way to the new coolers but need fitting size. can i change the fitting right in the tranny or just adapt to the fittings that are there already? HELP!

Thanks guys!

Well the trans is a female accepting the male flare on the hard line. Just looked at the trans line I replaced in the garage: tubing is 3/8", and the male fitting at the flare connection took a 5/8" wrench. So, I'd go to the hardware store or NAPA and find a fitting for a 3/8" line (that took a 5/8" wrench) and then find an adapter fitting that matches it. It's probably standard (diameter and thread) to a 3/8" line.

yeah why not just do 3/8?

i have an aftermarket tranny and having some issues with the temp (around 230 when towing) and i'm not happy with that at all. the guys i bought it from recommend a "aftermarket" tranny cooler for it but when i called and asked about the plug size they were no help at all. cost wise in not worried about the cost of replacing the whole line, i get all that stuff at cost through work. i just thought for cooling sake the more i can get in the line the better...... help drop some temps?!!!

Changing the line isn't going to help, you aren't changing the size of the inport and the pump is only going to flow so much. You need to just get the right cooler. Not sure what you bought but you should of bought the 6.0 cooler, I don't have the OTW cooler, the 6.0 cooler is my only cooler and I have never seen above 190 and that was working it hard. Don't waste any more money, stop and do it right, and you won't have any heat issues. PM me with any ?
