Bought 5 quarts of the Penzoil sychromesh oil
for my NV5600 . I'm at 70,000 miles so I though it was a good
time to change the oil. Pulled the bottom PTO bolt and nice
clean golden oil came pouring out Looks like new
Oh , well once it's out it's out. Time to refill with the new stuff.
Just glad I didn't but the oil at the dealer, they wanted $75.00 for
5 quarts

 

Thats definitely not a waste of $.

Your tranny will thank you with great performance.
