Sep 23, 2014 · With auto transmissions, it's also a common mistake with the slightly different OD of early (C4 to AODE) and later (4R70+) yokes causing slop and vibration. BTW - the marks on the short yoke in the photo concern me.

Oct 16, 2005 · I have my aluminum drive shaft INSTALLED! ye haw! My new C4 slip yoke has a notch where 1 spline is missing. My old one doesn't have this. I am just curious what this is about. Seems to me that 1 missing spline is 1 bit less strong but the new slip yoke is supposed to be a new fangled extra strong one.

Oct 11, 2009 · Apparently the slip yoke won't fit in the tailshaft housing bushing. The transmission is a brand new Mighty Mite C4 from Dynamic. I know new bushings can be tight but i lubed it with tranny fluid and i can't even get it started. Anyone have an experience like this? The driveshaft is a custom Moser aluminum and it slides right into the old C4.

Jul 19, 2021 · Working on buttoning up my 2 speed to c4 swap in my 64 and have a question concerning the slip yoke depth into the rear of the transmission. I’m using the stock length driveshaft from the 2 speed and not sure if it’s long enough based on the yoke depth at the rear of the transmission. Looks like it should be in further.

May 10, 2008 · So my math says that when I have my yoke all the way in, there is 3.5" of splines engaged (the forward 2" of the slip yoke sits "free" over an unsplined area of the output shaft), and even when the yoke is pulled out 1.5", the splines are still fully engaged (5.5 minus 1.5 is still 4" of yoke on the splines)

May 31, 2009 · I'm installing a 200/C4 from a '68 Mustang in my '62 Ranchero. (formerly a 170/3 speed manual). I know I need a different slip yoke. I want to reuse my original driveshaft. The u-joint is marked Spicer - USA,(inside C-clips) but there is no number on it. Will any C4 slip joint work? What do I need to look for? Thanks

Dec 12, 2008 · Remember when doing searches, there are different types of slip yokes. A fixed flange on the back of the tranny will have a slip joint on the driveshaft, these need grease and long-term durable grease is the way to go. Something like an auto trany where the slip joint is where the yoke slides in an out of the tranny itself, is lubed by the tranny.

Jul 31, 2011 · If the trans is a small in/out toploader or C4, you can slide the yoke over a 28 spline axle to see if it binds. Being able to have them both out in the open makes it easier to see the depth of engagement.
