hello all. i have a 96 f-350 4x4 351 5speed, it will not shift into od 5th gear, was this way when i got her, also grinds a little in reverse. i removed the top of the shifter and looked inside, the interlocktab that is spring loaded is broken off.will a standard 4 with od trans from a 92 f-150 with a 302 fit in my truck with a 351 . are the bell housings the same?i have a chance to buy a 92 f-150 4x4 302 5speed for parts. also my check engine light is on and the truck has a slight rough ldle.i have bought a code reader. where is the plug to hook up located.any pics of plug. thanks in advance.

 

the plug should be mounted on the driver's side close to the hood hinge on the fender I'm not sure the trannies are the same or not

 

The EEC test connector is under the hood, in the LR corner of the engine compartment, mounted to the fender by a plastic cover (if original). If it's been tested a few times before (it usualy has by now), then it's laying down on top of the wiring harness, near the Ignition control module.
The trannies should be all the same; the bolt patterns were. But keep in mind, some of the 4 speeds had a 'granny gear' which was geared super high, and isn't very useful when not trying to pull over a house.

 

One other thing; the EEC test connector has 6 slots, looks like a trapezoid, and has an extra pigtail (which is self test input) that must be connected to the tester to start the test. The code format is demand-seperator code-continuous codes. For example, a 111-10-172 means the on demand part passed (the 111), then the sep. code (the 10), then the 172 means that at some time in the past, the O2 was stuck lean, when it should have switched for at least 15 seconds.
Let us know

 

thanks for the input.not sure what you mean greasemark, are you talking about 1st gear being super low, which is what now have ,i need to start off in second gear.i would hope the od 5gear is higher so i can take it out on the highway. currently most of my driving in the city is in 4th gear. i have not bought the parts truck yet. will crawl under and check the tag on my days off. mine says zf.good description of where to plug in my reader. have not used one before ,,hope its straight forward.
