first this is not my truck it is my grandpa's 79 custom f-100, it has the 3 on the tree, but it keeps jumping out of second gear, we have tried rebuilding and replacing the tranny, when we found that the linkege from the shifter to the tranny is worn, well i was wondering were i could find the parts to fix the problem, and also what other parts might be the problem, thanks for all your help.

 

Check with the sponsor BOTP and others (check the list). This problem is often caused by rusted out cab mounts also.

Jumping out of second gear can mean only one thing. The second/third syncronizer brass blocker rings are worn. (Binding up in-between gears...[the shift lever gets stuck between 2nd and 3rd] is caused by something else ~ SEE BELOW). It's up to you just how far you wish to go in repairing the transmission. The best way is to replace not only the blocker rings, but all the bearings, bushings, seals, snap rings and washers. The parts are still available from Ford and NAPA. Your 3 speed transmission is officially known as: Ford 3.03 all syncro. Here are the parts you will need. These are the actual Ford part numbers, which NAPA can decode also. Most of the parts have been used since 1963, so finding them won't be a problem.

Here's one other fix your Grandad's truck needs:
At the bottom of the steering column are two levers. This is where the shift rods from the transmission attach. When the bushings in these levers wear out, the gearshift lever will bind up, usually between second and third gear. There are two plastic bushings and two plastic insulators, one per each lever, and are sold as a kit. It's also available from Ford and NAPA.

try rebuilding the column when they get slopy or worn out they dont like to stay in second gear

 

Cool thread you guys. :)

I've worked on stuff like this where the holes were wollered out from the plastic bushings being let go way-too long (if any). I tend to take it all apart and using a rat-tail file, carefully fix the hole to fit a brass bearing or steel sleeve, I either buy special or happen to have on hand.

They make flanged brass bearings too.

I think it's cool as anything when I can fix it up and make it work better than new. :)

Shimming the sides with washers and sometimes putting in spring-like "wiggle washers" and crazy stuff like that, whatever I think it needs. :)

Also there's those pre-made ball-joint things that are excellent but kinda pricey.
Heim-joint(?)

Since your problem could involve stuff inside and outside the transmission you can do one and then the other. Me, I'd do the outside stuff first and try it, then prob'ly do the inside stuff too anyway, knowing I had a good control system in place for the "new transmission". :)

Did I tell ya, I really like fixing up stuff to be better than new? :)

I have a 1979 F350 Supercab and it has a strangeness to it when shifting. It sounds somewhat like the above symptoms. Moving the shift lever through the gears feels stiff and clumsy and unnatural and the detents are not well aligned. I can certainly drive the thing fine but one has to be used to it. I am loath to let others drive it since they may screw it up. It takes some expertise to be sure you are really in D and not N. Once in D or N however all is fine.

Could this also be caused by the worn bushings in the column as stated above ??

Should I disconnect the levers to the trans from the column and decide if the stiffness is in the column or in the trans??

 

 

I miss them... and getting out to unstick the rods when they get caught between gears once in a while (while trying to speed shift...).

 

You have an automatic, so there's only one selector lever at the bottom of the column. There's a bushing there that snaps in, there's another one on the bellcrank, both are the same part number. There is no bushing on the manual control lever on the transmission. The bushings are still available from Ford.

E0SZ-7341-B .. Insulator Bushing (replaces D5AZ-7341-C)

 

F Series 3 speed manual transmissions have two selector levers at the bottom of the steering column. These have bushing on them. From 1965 thru 1989, there's only one type of bushings used..plastic ones. These are part of a kit (only one kit is required) and also includes two plastic insulators. The kit is available from Ford, and is a quick and easy fix to binding between gears.


1-C5TZ-7341-A .. Steering Column Selector Lever Bushing Kit

Fits 1965/89 (and prolly later) all three speed manual transmissions with column shift.
---------------------------------------------------------------------
From 1973/79, the 3 speed manual transmissions also have two snap in bushings on the tranmission levers. These are also still available from Ford.

2-E0SZ-7341-B .. Transmission Shift Lever Bushings ~ On the left side of the transmission. (E0SZ-7341-B replaces old Ford p/n D5AZ-7341-C)


The 3 speed manual transmission shift rods fit into the two steering column selector levers then go to the two levers on the transmission.

 

Here's a quick question for you, Bill. They still offer the rebuild kit (bushings) for the 1979 Ford F100 SROD 3 speed overdrive? If not, I'll slap something together, but it has like 5" of play in it. Not many people can shift it. I got used to it, but nobody else has. Might as well do it while I'm doing the frame off restoration.

 

The cab mounts being rusted out often cause the transmission to jump out of gear when the entire cab jerks on the shift levers....

Check & repair your cab mounts, fix the lever bushings, then worry about the inside if the problem isn't fixed.

 

Floor shift...there are no bushings on the 3 tranny levers, just wave washers, flat washers and the clevis pins. But on the bracket where the shift rods attach, and shift lever fits into, there are bushings there: E0SZ-7341-B. I'll betcha they are bad. Picture doesn't show how many there are. Those E0SZ bushings are used on a wide variety of applications.

 

Cool, that's likely it. I don't know why I didn't do it when I rebuilt the engine and trans...
