Transmission problem
1994 Ford F150 6 cyl Two Wheel Drive Manual 200000 miles

1994 Ford F150 XL, 2wd, 5 speed, Straight 6. Truck has had clutch and slave cylinder replaced in May. Approximately a month ago, truck would only shift into OD and Reverse. Was told to check clamp under floor gear shift, replaced entire gear unit. Worked for about a week, then same problem again. Took into repair shop, they replaced the boot and some bushings. Drove home fine, then within a few hours, same thing. OD and Reverse and nothing else?

Will the entire tranny need replaced or is this a repairable issue?

With engine off can you shift it in other gears ok? If it worked all right when they put the bushings in, check with the garage you had it repaired at. I would think it is in the shifter itself. Check the bolt and nut to see if it is tight. To me I would think it was in the shift linkage since it worked all right when they put new bushings in. The transmission can be repaired, you might find that a rebuit transmission might cost less than having the one that is in there now to be rebuilt. As I was saying check with the garage and see what they have to say.

Thanks for your response.

When engine is off, it will go in gears, when its running it will go into gears, but wont move, except for overdrive and reverse.

I would've thought that the shop wouldve noticed/checked that when it was there for this the first time, which is why we are no longer confident in their capabilities. We had called them back and they seemed to be puzzled as to what it was, so we were looking to have it checked out with a new facillity but would like to know what the probable causes would be, before they try and sell us on unnecessary repairs. Unfortunately, 9 times outta 10 even with something as simple as making sure bolts are tight, they will advise of more costly repairs.

We had spoken to another tranny person, who thought that maybe the sychronizer was bad since he says the teeth on those model years were very very fine and that could be an issue at this point. Also, someone else asked about the throughout bearings?. Any insight and/or advise is appreciated.

What he meant by the throw out bearing. It is what the clutch forks are pushed in with whenyou push on the clutch. If you have od and reverse and you can shift into gear with the truck running. Was there any noise when you did have all the gears from the transmission? If you had said it was not moving in first or second then I would think it was the clutch, but what you have told me sounds like the shifter fork is not engaging when shite into the other gears. Try taking the boot off again and check the shifter bushings. How is the transmission fluid?

What you just spoke of (fork) had been mentioned also before by a friend who owns a dealership. He described it as a horshoe type part.

When the truck was working, and all gears engaging, there was no noice coming from the tranny that we noticed.

It really was all of the sudden, it hadnt been slipping, sticking, nothing. Just all the sudden went to drive it and backed up. Wouldnt engage. At that point, we put another shifter in (from junk yard) the metal rings on the back of the ball were busted up. This is when it seemed to work fine for a lil more then a week.

When it started up again, we took it to the shop that did the clutch/slave cylinder. They checked it and replaced the boot and some bushings. We drove it home, approx 20 minutes to home, parked it. Approx 2 hours after parking it, the same issue started again.

We have checked the tranny fluid and replenished it.
