[quote=DIY.MechanicMike stuck in 5th/6th gear

Thanks mike[/quote]


Clear as mud, 4 forward gears on SM465.
What year / model rig you got.
Common for the 3rd gear countershaft snap ring to break allowing gear to move forward on countershaft.
The late design & service repair got rid of that snap ring & installed a spacer between it & countershaft input gear.
