I am not sure how to title this. My friend bought an A523 at the junkyard a year ago, I am going to help him go thru it to check it over. This will be being installed into a decently powered Holset fed Spirit R/T. The transmission in question is of unkown miles and origin to me. We are planning to go through it, replace what is worn and put it back together and put it in his car with a new clutch.
When going through an a523, what should I be looking for, what wears out, what needs replacing. I was thinking replacing all seals would be a smart idea. I did already pick up a set of Lengel's bronze for pads for this build. What should I be looking for? I have never rebuilt a transmission in my life.
Secondly, after going through this transmission, I plan to go through my own which is also a a523, using this one as a guinea pig first. What needs to be done to this transmssion to handle big power in my IROC R/T? (500whp)
My transmission is out of a 93 Shadow that was recently rebuilt before I got it, shift flawlessly right now.
I talked to Jackson and I am going to have the front case bearing on the main shaft welded to the shaft. I am also installing a set of Lengel's bronze fork pads, but this one is also getting an OBX installed. I will also replace all the seals on this one too. I think this should wrap up any weaks parts of this transmission, but what else needs attention?
Thanks
Forgot to mention, I'm adding drain plugs to both transmissions when they are apart.
