ZF Dash 2 Transaxle Gear Lube

jlbell4444Member

I had not changed my ZF gear lube in 14 years (3000 miles). Shame on me. It always shifted smoothly with no oil leaks. The only issue I ever had was some posi chatter when I was having some overheating problems (since taken care of). I read all of the posts on gear lube choices and decided on Valvoline dino oil hoping to stay leak free. I mixed 1 liter of Valvoline H. P. 85/140 and 2 1/2 liters of Valvoline H. P. 80/90 for a calculated 81/104. The label said it was GL-4/5. Its the slightest bit notchy (as good as it was) when ambient (85 degrees)and smoother than it was prior to the change after it warms up. Easy two finger shifts. After several 1/2 hour runs no gearbox or differential issues. Hope this helps anyone else agonizing over this.
