NOTE – THIS IS NLA FROM ME due to Duke’s pricing; I refuse to be associated with something so stupid.
Here is the Dukes transmission lubricant called out in the Comanche manuals special service instructions. It is a 2-ounce tube, adequate for 3 transmission services. I include 3 O-rings with the grease purchase; $93. Dukes number 4 lubricant [#4 lubricant], aka Dukes grease no 2196-74-1; according to Dukes these 2 specifications are the same. FYI – Dukes instituted a minimum purchase per invoice of $475 back in 2010 after the company was purchased and all the prices increased.
