Transfer Case Fluid Change
Have a 263 Transfer Case. Was told to use Dexron III ATF Fluid. When I drained the old fluid out (original) it looked like oil. Is the Dexron III the corect fluid.

Transfer Case Fluid Change
I am about to change my transfer case fluid for the 5th time in 180k miles. I have always used the GM owners manual recommended fluid GM p/n 12378508. The new/fresh fluid is a blue/green color and a dark dirty motor looking fluid after use. It appears that some DP members are draining the original blue/green fluid that looks like dirty motor after use and replacing it with ATF. Has GM made the determination that ATF is better than the owners manual recommended GM p/n 12378508? I have never had any problems with my transfer case and only want to use the best fluids in my truck. What is the VERY BEST fluid to use in my TC??????????
Thanks
John
