Hola from Tucson- Happy to find you folks here from that "other" site. I used this and the other site to help change the 4x4 disconnect box (passenger side) last week. I need to get busy and add my 2 cents on how I got it done. There's always a snag!
TODAY: I went to change the Transfer Case fluid. I'd previously called the dealer and confirmed by VIN number that my Envoy uses Autotrac II fluid, qty= 2qts. I've had a 2002 (built 9/2001) Envoy for about a year now. The fluid that came out was brown gear oil. It was the smell that told me it was gear oil. It was definately thicker than the new Autotrack II.
I probably got only a cup of the gear oil out of it. I put Autorack II fluid back in but it only holds 1 quart versus the 2 I was told (by the dealer and this forum) it holds.
When I got it, I went to a junk-yard and got the missing jack and a 2002 paper owner's manual. The paper manual calls for 75w-90 GM# 12378261, or equiv if spec= 9986115.
QUESTION: Did the last person who changed it put in the wrong stuff? Did any Envoy's use something other than Autotrac II? Is a 1 qt capacity normal?
If Autotrack II is the right stuff, I'll change it again in a week to purge out the gear oil.
Que te vaya bien!
