Need ZF5 Repair/Replacement
The ZF-5 transmission in my 97 F-250 bit the dust this weekend. I bought the truck about ten years ago and discovered that the transmission had a cracked bell housing that had been welded back together. All seemed fine, but there was a steady fluid weep from the top of the transmission which I countered by draining and refilling and correlating the fluid loss with miles driven and then topping off accordingly. This really was not to much of an issue, because the truck lives outside anyway and leaving a few drips behind was tolerable. Well, something changed and the fluid got much lower than I anticipated and the transmission failed. I drained the fluid and to my surprise there was less than a quart and a pile of metal shavings. Very frustrating, but the obvious argument is that the leak should have been fixed from day one and this would have never happened.
Anyway, not to dwell on my reasoning, now I am seeking advice on how to go about getting this repaired. I opened the PTO cover on the passenger side and took the attached pictures.
The truck can start with the clutch pedal down, but it tries to stall out in any gear, and even in neutral, which leads me to believe that the input shaft of the transmission is seized. Also, the truck can roll easily with the transmission "in gear." I put that in parenthesis because I suspect there is a missing gear that should be on the input shaft that turns the layshaft?
So, is a rebuild of this transmission even possible? Obviously if I can reuse this housing I will have the leak repaired while is down. Otherwise, am I better off looking for a re-manufactured unit? And if so, who can I trust to provide a quality unit? Lastly, throw out some cost estimations so I can start to financially weigh my options.
