‘48 Continental - problems with 2nd gear?


Recommended Posts

Guys, need some help.  I’m having a rough time engaging second gear and keeping it in second gear. Unless I hold the shift lever up, it will simply fall out of gear!  Obviously I have a linkage problem here, anyone know the first place to start?

It is not obvious that it is a linkage problem, let's start there. Check the linkage first as that might be it. Bad bearings and other things in the transmission can cause this also.

If the problem is in the tranny, you have to pull the rear end to get it off the motor.  Lots of work, but if you do go through it with all new bearings and gears that aren't perfect.  Remember Lincoln uses a main gear with more teeth than it's Ford counterpart.  Get the parts per the parts book from one of the suppliers listed in the club website.  If you have an overdrive that has to be rebuilt too.  U joint is also to be replaced.  And while you have it apart, it's best to remove the flywheel from the engine and have it resurfaced and 'trued' with a new clutch plate (Lincoln has a different one from Ford) and of course the throw out bearing needs replacing.  You want to do it right when you have it torn down as it's such a mess if you have to do it again too soon!  Good luck with it!

John, to check the linkage adjustment place the shift lever in neutral and then make sure that the shifting levers slide onto the shift levers easily. Check to see that the shifting lever grommets are not worn so that they move the trans levers completely into gear. There are kits to replace the worn grommets.

 

The shift lever detents in the side cover of the transmission could be worn. Check by removing the shifting lever for 2cd and 3rd, then move the transmission lever into 2cd and then 3rd, you should feel a positive engagement in both gears.  At the same time check for play in the pin that holds the levers onto the shaft. I don't know if you can get the side cover off without pulling the transmission

 

If that is OK, then connect the levers again and have someone shift the transmission while you watch the action to make sure that the lever moves far enough to engage 2cd gear.

 

If those thing are OK, then you may have internal transmission problems like worn shifting forks and synchronizers.

 

Good luck.

As usual, great info my friend.  Tonight I ordered all new grommets and bushings.  They were pretty loose and After replacing those, I’ll follow your suggestions.  Hope all are healthy by you!

Yes,we are all healthy. I have kept busy by fixing some of the small things on my Roundtuit list for my Lincoln. I haven't started on the shorter list that I have for my Mercury. With all of the summer activities cancelled there is no pressure to get thing done.

If all the previous checks out, I've had similar problem with worn brass synchro gears leading to falling our of 2nd gear.

Best of luck, Abe

Oh boy!  Sure hope I don’t have to go there!  🤨
