I was thinking about adding the Lucas additive to the transimission after reading some old posts on the subject. I went to NAPA but didn't see any Lucas product specifically for differentials. Maybe they were out of stock.
Anyway, what should I look for and what ratio would I use for a 4spd? The book says the refill will take 5.5 pints and I've already drained about 6. If I'm not mistaken that extra .5 looked like rusty water, how would that get in there? What's your take?
