Product Part Numbers
I have a 1986 C-10 Chevrolet pickup with a 4.3L V-6, 3 speed manual transmission and 2.73 differential. I purchased this vehicle new. It now has over 223,000 miles on it. I regularly changed the transmission and differential oil at 50,000 mi. intervals. The drive-train has been developing some noises (whine and slight vibration). I recently changed the transmission and differential oil to DuraBlend 85W-140. The transmission shifts as new and the drivetrain noises have disappeared. Great product!
