1996 ford 545d 4x4

[duelsport]

.I just picked up a 1996 ford 4x4 545d with a 8x8 synchronized power reversing transmission .when i have the power reversing lever in the neutral position the tractor still want to move forward or backwards . i have the ford service manual but I did not see any think about this problem in it.I believe that the neutral lock in the $500.00 power reversing lever is not working right.
before I but the lever I would like to check with the tractor by net people out their if this would be the problem. and help would be greatly appreciated


Thanks
