I have a new Ultra-Case trans ordered from JW Performance. They are closed for the holidays so I can't get any info from them. I am wondering what thread size they use where cooler lines are plumbed in. Stock PG has 1/8 NPT which adapts nicely to -4 AN fittings. Most trans coolers I've looked at, and the one I purchased, have -6 fittings, which typically are mated to a 1/4 NPT. Any help is appreciated--thanks!
