Hey guys I bought a rpm stage 5 t56 with 30 spline output shaft some years back (if I had to guess 5-6 years ago). Trans worked great till last week. Broke 2 teeth off of 2nd gear and 3 or 4 off the counter shaft. The other problem I found was the 5th and 6th gear cluster was NOT tight on the output shaft. I did not have a vibration in them gears and the splines look good. It was so lose I did not need the long puller to remove it. I did some reading and read some get sloppy and all goes to hell, bad vibrations, splines go bad, etc. Another thing I noticed along with this cluster is there are NO threads in the end of the output shaft for the installer tool to install the cluster when reassembling the trans. Im wondering if this is something rpm will do when building the t56 with the 30 spline shaft is turn the shaft down or the inside of the cluster so it slides on without the installer tool? If not how do I get the cluster back on if I buy a new cluster and its tight with no threads in the end??

There is a kent-moore tool that's used to persuade the shaft back on. But, if you plan on reusing that shaft you won't have any issue with it falling in. You can have the shaft built back up on that journal so that it makes it a press fit again.

yes i am aware of this. my question is does rpm do this for a reason? like i said it has no threads in the end so if i fix the shaft how do u get the gear cluster on? i know i could have the end machined with threads but by biggest question is y is it like this to start with?? i have a sent 2 emails to rpm and nothing back...

The reason it is like that is because the shaft is longer than an f-body. So, it is cut down to size. Once it's cut down there are no longer threads left over. Like I said, the kent moore tool will get the 5/6 cluster on without the threads.

that makes sense. for the tool your talking about, that does not need the threads in the end? the one im thinking about needs the threads.

I've never used a special tool to install that cluster. Pop it in the oven for 20 mins at 350º (won't hurt the heat treat) and usually they'll slide right on by hand.
