I am considering changing to my old cooler setup from the race car (all braided lines and huge cooler. The racecar had a TH350 but should all be the same really...) My questions are A: is the fitting IN to the transmission for feed and return lines a 3/8" NPT... B: the stock lines, do they go directly to and from the stock cooler, or do they feed/supply anything else with fluid (i.e. power steering cooler, etc) thanks for any advice or info.

 

a) I would assume the tranny threads are still the same size: 1/4 in. NPSM
b) tranny lines go from trans, to radiator cooler, to external cooler (if applicable) then back to tranny.
