Fourth snowfall here in Minnesota - last night noticed some 'late' or 'loose' engagement when shifting from R to L1, occasionally from L1 to R.
Best way to describe the problem would be a loose torque converter, or loose clutch, allowing a momentary 'slip', resulting in slight rise in RPMs, and a soft 'bump' when the gear engages. Happening about once in 15 or 20 shifts, when it does occur, it tends to repeat itself in groups before disappearing to normal tight gear engagements.
I don't recall this ever happening in the first three snowfalls / snowplow sessions. Snow was not particualrly heavy or wet. Always brake to a complete stop before reversing - and with brake firmly engaged to ensure wheel movement has stopped.
One other variable - yesterday did a 7qt drain and fill with new spin-on filter, and my buddy used Amsoil synthetic ATF...
Go back to Dextron VI and see if it disappears? Damn it would take a full 18qt flush...expensive test. Defective filter? It was an OEM Delco.
Thoughts?
