Next weekend I'm going to run some Seafoam through the engine (4.2) and drain and refill the trans and front and rear dif. What are your thoughts on fluids for the trans (5 speed) ? I've read all the Redlines/10-W30/syncostuff. What's my best bet. Trans shifts OK, no grinding going in any gears right now. Stock tranny in a 88.
