I'm going to be replacing my tranny and diff fluids and am thinking about going with Redline based upon some recommendations I've received. Anyone know which of their fluids is best for the S2K for tranny and diff?

Thanks.

 

For transmission, I have always found genuine honda mtl seems to work the best. redline is a close second but at a much higher price. As for the diff, I use Kaaz fluid (have to with my diff), so I don't know about the redline.

 

I've used redline in the past. Expensive stuff, very slick, definately the best of its kind. The oil, even though it costs 7.95 to 9.95 a quart (yes that is right, for one quart), they say it will last 12,000 miles / 12 months. Seriously!

I know their stuff is good, but is it optimal for the S2k? I am not sure if I'm going to play that game again. Before, in the late model Mustang, I tried lots of different combinations with the tranny and engine. For the Money the Mobile 1 always worked great. I ended up with Mobile 1 in the rear and engine (0w-30) and in the tranny one quart Mobile 1 auto and two quart Mobile 1 manual - it makes it a little slicker and shifts a lot better. With Mustangs, you can rebuild the tranny in a few hours and they break often (I went through three of them) so it really wasn't a big deal.

Well that's my two cents, if it means anything at all. I do recommend the Redline stuff, but its really slick synthetic stuff, and expensive too!

 

I have used Redline products for years in the racecar.
I put Redline MT90 in the tranny and used 75w-90 in the diff.
The MT90 is no longer in the trans because I haven't changed it since the 1-2 syncro was fixed.
I like there stuff but it is expensive.
If I had to pay for it I am not sure I would have used it.
I put Mobil one in the motor for but I am thinking of going to GTX.
