c4

i need help i bought a 200ci with a c4 trans to install to my falcon {64} besides minor adjustments it fits but the yoke does not fit {did not know they would not } my car has the 7.5 axle 4 lug change later ? can i just connect the yoke to my original driveline { i do not have the yoke that was in the mustang } using some kind of adapter or diffrent lenght size u- joint ??? also i counted the splines on the rear of the trans c4 have 24 for old models and 26 for new ones right i counted 28 on my trans counted them three times ?

Where did you ever get the idea that the rear splines would be 24 or 26?

The only output shaft spline counts I ever remember seeing for any Ford transmission were 25, 28, and 31. C4s have 28.

You will need to find a 28 spline yoke that will fit your C4 tail housing. You may be able to simply replace your current yoke if the U-joint is the same. Otherwise you have two options. First, find an offset U-joint that will connect the two, but that is not a likely solution. Or, take your driveline and new yoke to your local driveline service center and have them make the needed modifications to make it fit, usually costing around $150.

Sure, that is very common. DANA/Spicer (for example) makes adapter U-joints that are one size on one side and a different one on the other. The most common adapter joint used is the Spicer 5-134x which is a series 1310 to 1330 type. You can find these joints at well-stocked local stores (I found one I needed at NAPA) or online. Ford Motorsport even has their own like here:

Just get the yoke that fits your tranny, and measure which size joints are in that and your driveshaft. Verify your overall length and go for it. Local driveline stores are usually happy to help if needed.

WOW!!!!!!

Thankyou for all your help all of you . any images regarding linkage from my trans which is a floor mounted version to a columm shift would be appreciated also which hose gets connected to what part of the motor coming off the fire wall

these questions need to go in the garage forum or the falcon forum -- keep this clear just for C4 trans questions

slow down -you have 3 questions all rolled up into one--

first-- i believe the standard linkage points the opp way from the auto-- you need to reverce it -[ i may be wrong here with out looking its hard to tell]

now -- what hose you talking about -- power steering ??-- heater ??

vac line for power brakes??
window washing line??-

vac line to auto trans??

what hose?

Sounds like he is confusing the input shaft spline count with the output shaft spline count.
