I'm not knocking what you advised. Changing the gear oil might very well be in order. But GM synchromesh manual transmission fluid is more expensive than most synthetic gear oils. Also I think it is the wrong grade for use below 50*. 75W90 is good for all temps.
Yeah, the viscosity may be wrong for these temps. I'll have to look and see what grades they make. Hmmm
