Like the title says I lost the brass fittings that connect the transmission lines to the cooler. Can anyone tell me what size they are so hopefully I can source them locally?
Can confirm. Just did this job plumbing the tranny into my radiator and external cooler. I have a GN1 radiator, but the fittings/fitment should be the same.
90 degree fitting on the radiator:
-The male end going into the radiator is 1/8 NPT.
-The female end to the transmission line is 5/16 Inverted flare.
When I plugged mine I used a 1/8" NPT. I used the oil cooler fittings for my trans cooler.
