Ok i have a 63 394, slim jim. Looking at others coments would it be wise to install an inline trany filter between tranny and cooler and a drain plug instead of paying big bucks on a filter kit? And any other sugestions. Plan is to cruise with car after tweeking for fuel economy.{ laugh now but last project 67 mustang 32mpg highway and plenty of snap to woop a stock 2011 boss.} and thats with 2bbl carb 289ci point ignition and a three speed. Maybe an aftermarket cooler? Thanks for the help.

 

The factory filtering system functions just fine. Maybe change that filter every 100,000 miles or so? I see no need for an add-on.

I do not understand your question about adding a drain plug. Are you saying the '63 auto trans does not have one? I owned a '63, but that was back in gee, the 60's!

 

Tranny coolers are great if your pulling a boat of travel trailer in the summer. Other than that no needed IMO .

 

Was wondering because thry are said to be touchy. My uncle had a th350 he hauled heavy with. And when he died thr truck had over 500,000 0n it and he never tore it down.{he was original owner bought at the dealership where he was a tranny tech} just changed fluid and filter every fiteen thousand. I know the cooler the better and filters are a hundred bucks. Im hoping to put some miles on it, interstate ect. And service int is 26,000. In the book

 

No need for a drain plug, easy to drain fluid by removing the dipstick housing from the side of the pan. Drop the pan to be sure it is clean and replace the original filter which is available from Fatsco.
