RS800 transmission reverse is weak

[Craftsman Garage]

My craftsman T3000 is losing its reverse drive, it has the general transmissions rs800 cvt transaxle. I replaced the belt and cvt pulley only a few months ago. The belt has a small bit of wear but doesn’t appear stretched. Is there any adjustment somewhere in the linkage that I can adjust to get reverse back or what do you think? Forward hasn’t changed and is still quick and strong.

Test the power of the drive system to determine if it will spin the wheels in reverse . Chock the front wheels and determine if the cvt will spin the rear wheels .
