slip yoke problem / TF 727

what do you mean by different spline angle? can you show a pic or a link that shows that? and what is the cutoff year for those? i have a 67 727 that was missing a yoke and i pulled one out of a 84 dodge van that slipped right in.

2 different types of splines, you have to have them in front of you, one is sharper and the other is lets call it dull, the 727 is sharp, the 500/518 and the 42rh46rh/re all went to the convo style and what happens is the splines in the slip for the con spline interfere with the straight inv of the 727 spline making it a TIGHT fit, which if this was a end yoke....not a problem...

The change in the spline cut was around 90 or 92

dennys changes part numbers so no one can help you other then them
