Purchased my truck with 104,000 mi. Did not appear that the trans or rear axle fluids had ever been changed. Decided to run Royal purple syncromax in the trans.
When changing the fluid i noticed the magnet inside the pto cover had some metal flakes but not overwhelming. Long story short, i ran syncromax for 16000 (6qrts) the truck was always hard to shift, hard to down shift Could only catch a gear or two) and sometime nearly impossible to get in gear if it was at operating temp and I put it in neutral at a long stop light.
Switched fluid out today and the magnet was buried in metal flakes/shavings. Replaced the RP syncromax with 6 qrts of pennzoil syncromesh. Truck is already upshifting way smoother and i'm able to down shift now. drove 15 miles city and stop and go and 18 miles hwy. This is just my experience fwiw.
