Yesterday after a long wait I finally got the tags for my Fury back from the state. First thing I did was take it out on the highway and my worst fear was confirmed. The car would not go into third gear. First things first, this is a 1965 Fury III with the original poly 318 and original 727 torqueflight. At least that is what the guy I bought it from said, I never checked the numbers. I have driven it around the neighborhood a lot and never had a problem. I have noticed that the gear selection needle is usually a bit off. (it shows neutral when going into reverse, etc.) Also I have noticed that on occasion it goes from reverse straight to drive. Although after it is in drive if you shift up neutral is sometimes there. Last night was her first voyage on to the highway since I have owned it. And like I said it wouldn't go into third. However I met up with a friend and took him for a ride and I got on it a bit geeting on to the highway to show him the problem and it shifted into 3rd just fine. But it was only that one time, I couldn't get it to happen again. The tranny fluid seems to be nice and red and doesn't look dirty or anything. It looks like it might be overfilled, but I had to check it in park, as Neutral isn't always there. I have heard that checking these in park gives a bad read as the torque converter doesn't fill with fluid. The car seems to shift smooth, there is a bit of a clunk in the rear when you first put it in gear but I assume that is just a u joint starting to show its age. And it isn't any worse than any of the older trucks I have had. On one occasion it did want to slip out of gear when coming off of a stop light but I had been playing around with the gear shift trying to see if I just wasn't getting it in the right spot. Looking under the car I did notice that there is an opening at the bottom of the tranny housing where you can see the flywheel. Is this normal? I doubt it has anything to do with this problem, thought I would mention it just in case. I don't see any leaks from the tranny. Several small oil leaks but nothing else that I can find. I am thinking that the linkage may be off somehow, but before I attempt my first transmission repair I figured I would ask the experts. Thanks for any help or guidance.
