Looking for some guidance. Picked up a 55 Crown Victoria to work on with my 20-year old son. The vehicle originally had a 272 (based on the plate), but now has a 292 with the newer distributor and a 2-bbl ('57 Autolite carburetor). The young'un and I got the motor running recently (car hadn't run since the early 1970s) and while we are currently focusing on the cooling system, we will soon be checking out the tranny. Plan on putting the rear on jack stands and seeing if she engages. Before we do that though, wondering if it is best to drain and replace the fluid first. Looked for a filter kit, but told none are available. Does this sound right? Also, what transmission fluid would folks recommend we use. Any other thoughts before we tackle the tranny? Things we should be on the look out for? Pitfalls to avoid, aside from working taking this on as a father-son project ? (We will either grow closer or grow farther apart, though hoping for the former).
