JCI 4l60e driveshaft fitment question


Recommended Posts

Hello. I tested the fit of the JCI driveshaft in my 280z with LS1 and 4l60e. The driveshaft slides all the way in the transmission and then pulls out a bit once you get the flange lined up. 
 

It seems to pull farther out than I would suspect. About an inch and 1/2. 
Does this look correct?467FA271-3D9C-4406-BAF8-7933CFF524C2.jpeg.2c62ff80da1c1dc6aa9f78d9c2facd29.jpeg

bummer was really hoping for a yes that is normal answer! 
 

Here are some more measurements.  The transmission shaft sticks out about a 1/4 to 1/2”. The yoke is about 3 3/4” and the splines go all the way to the edge  


I can’t math real gud but that leaves about 2 1/2” of spline contact. 
 

My gap is 1 1/2” If the normal gap is 3/4” would it be worth redoing the shaft to add 3/4” more contact?

I hear you, in my case I had no choice. Mine was leaking from the rear seal. I replaced the seal twice and still leaked. I was also told that not having proper engagement could damage the transmission bearings in time. You can always try it like I did, if you have no leaks or vibrations you may be ok.
