Cool I'll probably do this as I'm about to have to buy differential fluid as well and don't want to have to spend any more money by buying a hand pump.Or you could just take the shifter off and fill from there. Obviously stop filling when it comes out the fill hole
Well the fluid is mostly full. Just a little leaked out from removing the driveshaft. If I don't have to flush it that would be preferable which is why I'm wondering if I can do it without over filling it while just topping it off to the right level.brtnstrns Take the shifter off and dump it in. A tr3650 takes 3.2 quarts of GM syncromesh i use the penzoil in the yellow bottle and it works good. Stay away from royal purple.
