I have read a few post on this and i am still unsure. I have a 03 DC prerunner 4 cyl with TRD. I have the ECT button on the left side of the dash, best i understand it only changes shift points. should i have a lock diff button? I have read posts saying i should, and post saying i should not.
Not all the post were on this forum, not sure of their validity. I have not seen both mentioned together. Just trying to understand, thanks in advance.
