Great for Gm maint

Used this in my 2001 Chevy Tahoe transfer case and my other Chevy vehicles that recommend this. USE THIS AUTO TRAK II and nothing else!! It has greater corrosion resistance !!! Buy you a screw on pumper with hose for the top of the bottle. Takes about 100 pumps each bottle but I was finished in like 15 minutes. Beats trying to funnel it into the hole under the vehicle. Mine used about 1 7/8 quarts before it started over flowing out of the top plug. All you do is remove the bottom plug on transfer case, let fluid drain, install bottom plug back in and tighten, take out top plug on transfer case, start filling with fluid until it starts running out of the top hole. Make sure you vehicle is on level ground.

The item pictured in the listing is shown with a standard size spout. The bottles that I actually received have the large (oversize) spouts, therefore not allowing me to use my fluid pump which is necessary to install the fluid.
