Default Powerglide Thread Size

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!

Most aftermarket P/G cases have 1/4 npt and use-6 coolant lines. If you want to use your -4 fittings you could use a brass step down adapter.Hope this helps

Thanks Craig, I was really hoping to avoid using adapters. My new cooler has -6 fittings.

No matter what….-4 fittings are too small for cooler flow.
