My 3T40 3 speed finally let go after 190,000 Miles. I got a "fresh one" from a junk yard with 68,000 miles on it. Before I swap them, is there anything I should do while the tyranny is out of the car? I'm going to put a fresh filter and fluid in it. And I'll use the torque converter from the donor car because it has fewer miles on it. But I didn't know if there were any other things I should do now to save time and aggravation later. Please & thank-you, any advice would be appreciated.
