Transmission Spline Shaft Counts

Recommended Posts

Ok, I've searched extensively and have yet to come to a conclusive answer.

What are the spline counts for the various transmission input shafts?

I can find axles by the pageload, but never the input shaft spline counts.

So I want to collect all the info and submit it into the USRM for safe keeping.

I'll give credit where credit is due.

 

So, fill in the blanks.

EA71 FWD transmission input shaft has __ splines

EA71 4WD transmission input shaft has __ splines

EA81 FWD transmission input shaft has __ splines

EA81 4WD transmission input shaft has __ splines

EA82 FWD Transmission input shaft has __ splines

EA82 4WD S/R transmission input shaft has __ splines

EA82 4WD D/R transmission input shaft has __ splines

EA82T FWD transmission input shaft has __ splines

EA82T 4WD S/R transmission input shaft has __ splines

EA82T 4WD D/R transmission input shaft has __ splines

EA82T AWD transmission input shaft has __ splines

EA82T AWD D/R transmission input shaft has __ splines

ER27 FWD Transmission input shaft has __ splines

ER27 AWD transmission input shaft has __ splines

EJ transmission input shaft has __ splines

 

I hope that covered all of the options up to the old gen.

Now this is obviously just manuals.

So please, answer as accurately as possible and remember, this info is going to be put into the USRM, so please keep the useless banter and off topic posting to a minimum.

 

Now I'm going to post some seemingly useless tags for easier referencing for the future.

I know the axle shafts are 23 and 25 splined respectively.

I want to know to tranny INPUT shaft spline count.

 

The axle spline counts are everywhere, and easy to find.

The input shaft spline counts are a lot harder to come by.

EA82 FWD 21x7/8"

EA82 4x4 24x1" (I don't think this is always the case)

xt6 24x1"

ej 24x1"

Hey, this guy's new AND helpful ;)

Thank you very much, I'll be cataloging this and awaiting more info for verification purposes :)

 

Lets see what everybody else knows...

OK, so I verified that the XT6 Clutch disc matches the input shaft of an 85 EA82

Part-Time 4WD d/r.

That pretty much guarantees it'll work with the rest of the EA82 Part-time d/r's.
