310J Fault Code

Need some clarification on what this JD fault code is. 2320.09 It was a stored code, no active codes. The sympton is the machine has no 2 gear in forward or reverse. The back up alarm activates when put in reverse but no movement. All other gears are fine. This is a powershift machine so it is all electronic unlike the syncro-shift that about 90% of the other 310J's have. We swapped the FNR lever out and nothing changed. Curious is any Deere dealership guys could lend a hand.



Thanks!
