    2003 Allison c1 clearance

    Thanks Logan. I sent my stock c1 top plate to the local machine shop. He wasn't sure if he could cut it down for me but said he would try it.

    I was checking the clearance with only 1 snap ring in place. I left the spiral snap ring out.

    2003 Allison c1 clearance

    Evan I pulled the top plate off the clutch pack and measured it. The plate is 0.390 thick. Also I remeasured the clearance. This time I used two feeler gauges. 1 on each side of the pack. My actual clearance is 0.130 inch.

    2003 Allison c1 clearance

    I used a feeler gauge on one side of the pack. I used a flat screw driver to hold the other side of the pack against the snap ring.

    2003 Allison c1 clearance

    I never measured the top plate. I just installed the plate that came with the kit. Is there a different thickness of plate available?

    I am working on a transmission rebuild. I am working on a 2003 LB7 with an Allison. The rebuild kit is a Suncoast Gmax-5R-3. Everything seems fine except my clearance on the C1 clutch pack. The clearance measures 0.125 inch. The spec is 0.090 to 0.115. How can I correct this?

    Allison 6sp: no 4-5-6th gears

    Thank you for your input Mike L! Thanks to everyone else as well! The DB diesel converter has not been shipped yet. I am from Canada and getting a Suncoast converter sucks because of shipping such a heavy item across the line. I will do my best to get one tho. Goerend is also a US company I think.

    Allison 6sp: no 4-5-6th gears

    Does anybody make a stronger front support and stator shaft? Or do I have to just order the shaft and front support from the local GM Dealer and hope that the new shaft will not spin?
