How do I swap a 3 on the tree to 3 on the floor?
« on: November 01, 2013 - 10:47:16 AM »
I'm thinking of picking up a new project that has a 3 on the tree.   I'd want to swap it to a floor shift right away.  I had a manual 3 speed in my first challenger and didn't mind it a bit, it was pretty cool once I finally got the linkage and shifter working correctly.   That was many moons ago. 

What do I need to install a floor shift instead of the column shift? 
Is there a bracket on the trans for the shifter to bolt too?   
Do I need new shifting rods?
Can you still get a 3 speed shifter for that application?

Any help you can give me would be great!

Thanks,
Chris

you will need the shifter mount bracket & shifter as well as the rods & probably a floor hump to clear the shifter as well , not sure where to find the shifter , I would start with swap meets or used parts dealers

Sounds easy enough, anyone have  leftover 3spd they swapped for a 4spd?

I wonder if the generic ones they sell in Summit would work?

Thanks Chryco

One other thing to do is to completely dissamble the steering column and transplant the shift indicator portion to a non type like what floor shift car columns are like.

So it sounds like the shifter is mounted to the floor bracket instead of the transmission, is that right?  Or is there a bracket that you add to the trans?

Thanks

I'm curious as to whether or not the three on the tree has a floor hump added for the manual trans.  Regardless of the shifter. 

You might get lucky with that one and not have to graft in a new floor hump and cut out the auto hump.

If you put a wanted add on a few mopar boards, I'm sure you will come up with a three speed that someone doesn't need from a 3 to 4 speed switch.  Pretty common item.

I'm sure you've thought of this, but since you're already modifying the car why not just go to a 4 speed / pistol grip?  Parts would be easier to find and possibly cheaper since they're more common.  Just a thought.

My thought it just to slap a floor shifter on it in an afternoon and keep it on the road.   I don't have the project car yet, but seem to come across three on the tree semi-regularly and thought that would be more fun to tool around town with a floor shift.
