I got a 74 F250 Crew with 360 & 4 speed manual & tow package. I was wanting to know how hard would it be for someone to rebuild the trans in it? I have never rebuilt one before so this would be the first time. The problem is the pressure plate is missing for the clutch so you have to turn it off to get it into gear I am going to replace the clutch & was wanting the trans rebuilt at the same time. Also were can I find a replacement clutch for it at? I live in Charleston WV.

 

you can probably find a clutch at your local parts store, like NAPA or autozone. and ive never rebuilt a tranny, so i dont know how hard it is, but id say go for it. just like everything else, remember how it came apart. if you need, use a digital camera to take pictures of everything as it comes apart.

 

It's a ridiculously simple transmission to rebuild (i'm assuming you have a np435, if not the t-18 is very similar) a complete master rebuild kit is under $200 either thru Novak or JBG...Parts for the New Process 435 Transmission

 

I concur with Montana I've done several and they are very simple! Since this is your first I would recommend laying all out in order you took it a part and then reverse the process.

 

And keep everything very very clean!!!!!

These trans are very tough but if its been used without a clutch it could have major damage. If the gears are trashed it could become expensive quick. If that turns out to be the problem it would be cheaper to find a used trans.

 

Sounds to me like your clutch fork is broken or the thowout bearing. If you didn't have a pressure plate it would not go anywhere. I say replace it with a full clutch kit and if the clutch fork is broken replace that. Then change the trans fluid and continue to drive it. Just my .02

 

What leads you to think the trans should be rebuilt?
Excessive gear noise
difficult to shift
grinding noise
HOw many miles

Curious is all

I rebuilt one for my 79, mostly because some **** dropped it and bent the input shaft.
it was my first manual Trans rebuild Silly simple to do.

 

yeah I'm with JLaudio. If you still have all the gears and the synchros are working why worry about the trans rebuild. I'd get the clutch workin' then see what condition the trans is in.

 

it just this will be my daily driver an the trans as far as I know works fine. but the pressure plate is missing its a 2wd. An it will go into gear not running an then stop an turn it off to change gears. the guy I got it off of said the trans shifts fine an that he drove it around his property. but one of the receipts he sent me after I bought it was from the guy who bought it from the guy in CA an he took it to a shop & they told him back in Sept. 96 clutch SHOT trans. VERY WORN. so I was wanting to get it checked to be on the safe side.

 

an the shifter seems to have some play in it.

 

NP435's have 2 nylon bushings on each shift fork. When these wear down, slop begins.

The 1-2 shift fork nylon bushings are not the same as the 3-4 shift fork nylon bushings.

The NP435's shift lever retainer cap has two notches on it, is retained to the shift tower with two pins that protrude from the tower.

Trans in neutral: To remove this cap, it must be pressed down on...and held down while turning it 1/4 turn to remove it.

Ppl do not know this removal procedure, use pliers to get the puppy off. This tears out the two notches...now you aren't going anywhere.

The T-18 cap threads on/off.

 

Do you know much about clutches? The pressure plate is what puts pressure against the clutch disc and jams it into the flywheel. The clutch disc is the only thing connected to the transmission. Without the pressure plate pushing the clutch into the flywheel the transmission would not turn. So if it will go forward but not disengauge then your clutch is stuck or you are missing a clutch fork or a similar problem where you cant disengauge the pressure plate. If what you say is true about the tranny then I woud just get a junk yard trans.

 

It could be out of adjustment too. if the clutch will not disengage then it may just need to be pushed a little further. there is a threaded rod linkage that could be lengthened to puch more on the pressure plate.

Worn Clutches slip. broken clutch forks or out of adjustment cause clutches to not disengage. which sounds like your problem as you say you have to turn it off to shift.

might be as simple as tightening up the linkage adjustment.

 

I dont know anything bout clutches or anything like that but the guy helping me had me to push in on the clutch an he adjusted it an then he got looking an said there is no pressure plate there it is missing. I found a couple of people who will look at it an tell me what might be wrong with it. I am going to keep this trans unless the housing itself it junk then I will replace it. But I want to keep this one since this is the factory trans an the truck only shows 30,105 miles on it. I was wanting to keep this truck as close to factory spec as I can an just add the things that were optional for that year an add cruise from the 78/79 an later add the woodgrain from the 78/79 an thats it. That is why I am swapping the dash out for a dash with factory air an going to install it. Next I will be looking for what two tone was available for the Wimbledon White an do it two-tone when I paint it.

 

If the truck has been sitting and the clutch pedal feels normal it could be just a stuck clutch or even a dry and binding pilot bushing. If you're going to be using it for a daily driver I would stick a clutch in it and drive it and see how the tranny feels and sounds.
You are only looking at an hour to pull the tranny back out if you want to rebuild it, unless it obviously has some slop in the shifter, then put the bushings in that number dummy suggested while you have it down. you can always drain the oil and see how much metal is in it before you even start.
