I read the Richmond Super T-10 service manual (after I already had my transmission assembled of course) - which I assume is going to be the same for the Borg Warner Super T-10 - and it says NOT to use grease to hold loose bearings in place while assembling the transmission because it won't dissolve in gear oil and grease doesn't provide adequate lubrication for the moving parts; instead they recommend petroleum jelly. I tested this out with regular black moly grease and sure enough it doesn't dissolve completely in gear oil: working it around in the oil with my finger just causes it to break down into small clumps. Unfortunately when I assembled my transmission I followed a video where the guy doing the rebuild says to either use grease or assembly lube (which he uses), and I of course used grease. Now I have a dilemma: should I disassemble a large part of the transmission just so I can clean the grease off of the loose bearings and reassemble them with petroleum jelly, or should I hope that the grease will eventually work its way out of the bearings so the gear oil can get in and properly lube them. Anyone used grease to hold bearings in and NOT had any issues down the road with premature wear to the bearings, etc?
