I am currently towards the end of a 1276 restoration project, I just got everything back together and sent power to the transmission for the first time. Without the pump on and the gear in neutral, I can spin the axels by hand, one goes one way, the other, the other way, giving me indication that I don't have a differential problem. When I put power to it, everything appears to work as advertised, except when in gear I can stop the Axel from spinning with my hand, little to no resistance. I do have a bit of a rigging problem from worn linkage, but I can move the cam by hand to get it fully in gear. The tow gear in completely closed. Just flushed and filled with fluid. I have not changed the filter.
Any idea on why there seems to be no power in the axels??
