Quick flm tranny question

I will try it Ross, i have 7000 here. For now, i use industrial extrem pressure red grease in the diff and inside the tranny case to lubricated the gear, but with this grease in the diff, the diff is realy too loose, i do not like the action of the diff.
I will try with 7000 or 10000, because with my Neu 1512 on this little truck, the tranny will take a beat

Another question, did you use the stock slider or you have replace it with a CVD kit...
