I have a 56 Victoria with the 292 and Fordomatic that I successfully rebuilt myself using a rebuild kit, a factory Fordomatic shop manual , and a little help from experts. It has run and shifted fine for about 50,000 miles. All I did was add a little fluid once when it was a little weak and sluggish on engagement in drive. It has started to do that again. The engine revs a little higher to get the car moving . This afternoon I will check fluid level again and add if necessary but wonder If I should change fluid and screen. The manual suggests a complete fluid change after 25,000 miles. If that is the case, I am way overdue. By the way, I have driven this car daily for years. I hope to just add fluid and not drop the pan, filter and mess with band adjustment. I guess my big question is< After 50,000 miles it is a no brainer to need to change all fluid and a screen. I have also been advised to avoid a total fluid change if possible, Advise from a good fordomatic guy would be appreciated.
