    I believe the 9 represents the design level. The letter at the end is the ratio set. I know there's A and B for sure. Might be a C ratio set.

    Update on transmission:

    Everything fell apart coming through Music City and getting a Weller replacement here. Couldn't even let off the clutch in neutral without bogging down the engine. Spending an extra $500 to go from 13 to 18 just because all the truckstops i go to in MD, PA and WV seem to be at the bottom of hills and for 5 bills I can be nicer to the engine. I think I'm also going to say adios to the heat exchanger in favor of an air cooler for a few dollars more. Lucky(?) me, the trans already had the halo on it so I'm not paying for a new bellhousing.

    I'm also going to have them tap the ECM to see just my my HP is set at and if it shows anything that might be a problem later. Was told I might have a Signature 600 under the hood but I'm skeptical, having an 1850 lb/ft trans behind a 2050 lb/ft engine doesn't sound like a good idea.

    I'm running i dunno 2200 to 2300 ft lbs torque maybe(700-750fwhp) in front of an 1850 and haven't had any trouble in 6ish years. And I'm hard on stuff. Short hauls, soft roads and in a hurry
     
    Roberts450 and HoneyBadger67 Thank this.

    You'll be fine with the 1850 lots of big hp builds behind those
