Finding reverse gear and floppy gear shift
Hi all,
As described in my photo thread, I couldn't find reverse gear on my test drives. I now have the latch rod adjustment correct as per the service bulletins (it was only 1/16" off), and although it seems to be shifting the gear , I cannot get it to engage, I just get noise of gears grinding against each other. Not sure if it is related but my shift lever is really floppy and can move all over the place. There is a slot in the ball shaped piece that sits in the transmission tower - see photo- and am wondering if this is to limit movement but the only thing that would go in this slot is one of the screws that hold the ball cap in place. I tried putting a longer screw in but it just seemed to lock the lever up. Am I missing something here? Any help appreciated!

Re: Finding reverse gear and floppy gear shift
Check out the Youtube video, I think there are seven short videos on the repair you need.

Re: Finding reverse gear and floppy gear shift
Thanks Bob - didn't even think of looking on YouTube , those videos are a big help. Someone must have modified my tower and replaced the pins with screws. I'll bore out and ream the holes oversize and make some new pins and see how that works. Would you know how long the drivers side pin should be - I'm thinking if it is too long there wont be enough movement and if too short, there would be too much? Seems like the length would be critical.

Re: Finding reverse gear and floppy gear shift
Actually, the initial 4-speed shift tower (like shown in the video) didn't have a safety wire. And those special pins shown are not correct and they were not a press fit.Bob C wrote: ↑November 23rd, 2019, 1:04 pmCheck out the Youtube video, I think there are seven short videos on the repair you need.

Original pins were headless with a grove toward the outside end (AA-7224 short pin and AA-7221 long pin). To install, the cap was compressed (by hand) and the special pins installed (by hand) with the slotted ends to the outside. When the pressure on the cap was released, the AA-7227 gear shift lever spring pushed up on the cap. The cap then fit into groves in the pins to hold the pins. There was a long and short pin. The long pin was inserted on the left side and therefore fit into the slot in the closed swivel ball of the shift lever.

Here is a photo of the 3/30 Ford parts list showing AA-7221 long pin and AA-7224 short pin.

Thanks Neil, good info, I saw those pins in the parts list but didn't know where they went!

Re: Finding reverse gear and floppy gear shift
I machined up some pins and fitted them this morning and they have made a huge difference. All the gear positions are a lot easier to find and the lever movement is a lot more positive. Except that I still cannot get it to mesh in reverse. I am pretty sure I have the latch engaging OK and the gear is moving, otherwise I would not hear it trying to engage. It seemed to work OK when I tried it on the bench after rebuilding so I am totally mystified. Anyone have any ideas?

Re: Finding reverse gear and floppy gear shift
Hi Kim, I am pretty sure it did as it shifted into all gears on the bench. Not sure what you could get wrong assembling it anyway, as the parts can really only go in one way.

Re: Finding reverse gear and floppy gear shift
So, it sounds like everything is moving OK, but rev. is just not moving enough. Time to play detective!!! Pop the top off and look it over. Slide it into reverse with the top off, then see if you can get the top on with it in rev. This may help to see what is or is not moving far enough. My guess is that something is in backwards. Either the fork that engages the gear, or the gear it self. Is the gear being held in the proper range?
Just some thoughts. But you know what!!! when you figure it out you'll be happy!!!! Maybe... Please keep us informed / entertained...

Re: Finding reverse gear and floppy gear shift
Thanks Kim, yes I've come to the conclusion I'll have to take the top off it and look inside. If I had a dollar for every time I've taken the floorboards off I'd be rich! It'll have to wait a couple of weeks but I'll let you know what I find.

Re: Finding reverse gear and floppy gear shift
One thing I've noticed is when cold the trans may be sticky to find reverse.
I usually give the engine a good rev up and it slides in no problem. After the trans lube is warmed up I have no trouble at all.

Now that is interesting! I wonder how many other 'issues' are related to such a phenomenon.Farrell In Vancouver wrote: ↑November 27th, 2019, 10:11 amOne thing I've noticed is when cold the trans may be sticky to find reverse.

Re: Finding reverse gear and floppy gear shift
Come to think of it, I just had it idling for a few minutes when I tried it. I'll give it another shot before I pull the top off!
Thanks
Jeff
