Hello, I am planning on flushing my transmission fluid and differential fluid and I have a couple questions before I start. How do I go about flushing the differential and what fluid do I use for a limited slip differential? Also, how do I drain the transmission, and what fluid do I use for a 5 speed manual transmission?<p>Any links to tutorials would be greatly appreciated.<p>Thanks in advance.

Re: Question about Transmission and Diff. fluid (richardthepundit)

I'm the first one to tell you that this is an unorthodox answer, but with a locking differential, I would go to a Chevy dealer and get what they have for a limited slip diff, like on a Corvette... PLUS, get the little plastic squeeze bottle of the additive for the diff. That additive counteracts the 'slipperyness' of the oil and allows the clutches in the rear end to engage more and slip less. As concerns the transmission, I would use whatever is specified in the owner's manual. Since yours is a 5 speed, and not a four speed with electric overdrive, use what is specified. <br>For anyone out there with a four speed with overdrive, definitely use type-F, ATF. Type-F is less slippery than Dexron, and F is necessary for the clutches in the overdrive unit to engage without slipping.

If you actually do have the Dana powrlock clutch type LSD, you should use a fluid additive. There is a Ford Motorsport product that works well. It doesn't take much, either. Beware those who say "just dump in the whole bottle".<p>Type F ATF will work in the M47 or M46. Redline MTL works well too. Synthetic Type F ATF works well too. I've been using MTL for 5+yr in my M47s.
