1964 170ci/c4 combo words of wisdom

Hello All

So was able to get a 170ci in decent shape with a Fordomatic 2 speed with shifting issues (until warmed up). Have an opportunity to get a C4 auto with floor shifter out of an early Mustang. I currently have a fully functioning 144ci with 3 speed on column 2.77 manual tranny which I am thinking of swapping out for the 170/c4. Any words of wisdom/cautions for this? The car originally had a 170 with 2 speed auto so I have the auto pedal assembly and original auto column which I would look at a shifter delete and go with floor shift. Thoughts???

You can keep the column shifter if you want. All you need is a C4 detent plate that installs in the top of the 2 speed column. You can switch out the shift indicator with a 'green dot' one. Not sure if other 3 speed auto indicator will fit your column. May be able to use later year linkage to the trans.

For a floor shft, you'd want to get the collar off a floor shift manual column to eliminate the column shifter.

Can't advise for your transmission mount, several companies sell a c4 adapter mount.

C4 is going to have a larger drive shaft yoke and u-joint than the 2 speed. There are some 7-3/4 rear end yokes that fit the larger u-joint. I actually have one that I'm not going to use because I decided to swap rear ends. This would be better than running 2 sizes of u-joints. Drive shaft length may also be affected.

Forgot to mention, you might need to go at the transmission tunnel with a BFH or cut and move it up some at the firewall to clear the C4 bell housing.

"...words of wisdom/cautions for this?..."
U have "the Handbook", seen our tech archive?

Recent thread gave dement ions 4 above subject line DIY adapter...simple

Thanks for the info and advice frozenrabbit. Still debating the c4 due to all the mods required. I really don't want to modify the tranny tunnel to make something work. Also now looking at a t5 solution but that is $$$$.

Chad, have the handbook and studied it for options as well as other forums but nothing is jumping out as a workable/economical solution just yet.

Still thinking and weighing out my options......maybe just mate the 170 with my current 2.77 3 spd manual for now.

C3 auto is heaps smaller and found on 1978 to 1983 Fox cars. It had a Small bellhousing which jumps to 136 teeth like the C4, but it is physically a smaller automatic that, should fit. It has the same ratios as a C4, but was designed in West Germany for the rear drive Capris, Taunus, Cortina, Granada and Escorts 10 years after the C4, it uses a special flexplate and starter, but its excellent and cheap.
