"Although the customer is always right. You want the fluid changed, they`ll change it with an approved fluid."

I told him, "I guess I`ve been reading too much stuff on the web." Kind of wish the Official Chevy folks on the site would pipe up and give us some definitive answers...

They would tell you to follow the owners manual. Plan and simple. They can't say anything else but that.

Do you trust all blanket ambiguous statements? Everything in this world is unique, not one car is identical to the other. There are small differences that make each car different, one might be burning more oil, or the other has more metal shavings in it from break in. Who knows, but I do know that they aren't the same.

So why would I follow a unilateral service schedule that ambiguously applies to every Camaro owner in the world?

Regardless

I'm going to do change both the Tranny and the Rear Diff before 2,500. Whether I use a fluid of my choice or theirs, is yet to be seen.

Royal Purple Max Gear in the differential
Synchromax for the Tranny.

or Red Line products I am still doing my research.

Probably not. But just to point out the obvious, there's a little bit of a price difference between a new washer pump and a new differential.

Why not just clean the magnetic plug and put it back in. It did its job collecting debris.

Because the plug is on the bottom...
