We are currently replacing the clutch in my 92 (me and a certified Acura/Honda tech)... I have noticed that the book calls for 'Manual transmission oil' when refilling the transmission. Does anyone have any experience with putting 5w30 motor oil back in the tranny, or would anyone even know if that will suffice? Since it is sunday, I am stuck with no means of obtaining any Honda Manual Transmission oil. Please respond if you have any input on this question. Thanks. (Oh, by the way, i'm going with the Clutchmasters Stage 1. I'll let everyone know how it works out. Can't beat it at $895.00)
