Thank you.

 

First thing you can do is check for any slack on the linkage rod ends plus make sure the transmission lever (belcrank) is tight and not stripped. You can loosen the small lock nuts on the linkage,while in neutral tun the linkage rod until the shifter is centered in the rubber shift slot. This should leave plenty of room for positive gear engagement. If it still slips out of gear,then its probably an internal trans problem. Shift fork wear,engagement dogs on the forward gear worn not allowing positive engagement,etc. OPT
