Default Re: Transmission Oil

David J says he uses 140 in everything.
I checked the weather there last month and it was -20f three times when I checked.
My brother lives in St Croix Falls.
When I lived in River Falls I bought a ‘46 V8 off a used car lot when it was around 20 below zero.
After about 50 moles that day the rear end started to howl.
The local gas station had to use a blow torch to get the gear oil to drain.
I don’t see how he can even steer a car with 140 in the steering gear box.
Oh, and another thing;
If you put GL5 in a gearbox with yellow metals it will discolor the yellow metals after several years. It will NOT dissolve them in a few minutes like most people believe.
