getting ready to run trans lines to trans cooler and need thread size at trans to get adapter to -6 AN. any help would be appreciated so I don't spend more time running around then to do the job.(already blew rubber hose once not again)

 

TTT
I would like to know this as well.
How will you be attaching the AN line to the trans cooler?

 

I know on my GTO it is 18mm. I would imagine it would be the same on an fbody? The kit that came with my b&m cooler had 16mm.

 

sorry cant remember what size it was right now but if possible pull the fitting out and take it with you to have the hoses made thats what i did. If somebody hasnt posted the answer by the time i get home tonight i will check my reciepts.

 

On th 4l60E I am 99.9% sure that the size needed for those fittings on the passenger side are 1/4" NPT. Is that what you are looking for??

 

I spliced my tranny cooler into the return line out of radiator (fluid passess thru radiator first) ..... I used earls aluminum plumbing parts, the fittings for 5/16 tubing worked fine to make splices into tranny lines.
