What tranny fluid do you use?

[jolberry]

I have been researching a lot on this and have heard many "opinions" on both. I have already purchsed Mobil-1 75w-90 gear oil, But want to know which you guys prefer and why.

You'll find the majority of MME members use Mobil 1. It's cheap and available at Autozone.

Mobil-1

Like Sammm said, it's cheaper and is way more readily available around the Metromess.

It's also works just as good and is rumored to cause less notchiness in shifting than Red Line.

I had it in the tranny and diff on the 92B&T before I sold it. Shifted like a new car after the swapout.

When it comes time to do tranny maintenance on the '03 I will be putting Mobil-1 in it.

We have a winner!

Honestly, I tried Redline, and it was great... for a few thousand miles. Then it got kinda crunchy. The Mobil1 75w90 seems to work just as well, and it works well for a longer period of time.

Some of the S2000 guys use GM Synchromesh stuff, supposedly because the friction modifiers work well with the Aisin 6-speed they use. I might try it next time just to see if it is an improvement or not.

I am experiencing a little crunchy when going into second when the car is not warmed up. This is what prompted me to want to change the fluid. Like I said I have already purchased the Mobil 1. Just wanted to make sure I made the right decision. I am going to attempt to change the tanny/diff/turret oil sometime this week. It looks fairly simple according to this http://www.miata.net/garage/trans/everything.html

Just be sure you can get the filler bolts out before you drain anything!

My '96 could use a change. Anyone up for a GTG?

I am :)

^Dammit, another GTG when im broke

[jolberry]

No one has set a time or place yet. My schedule is wierd this week and I will be out of town all weekend. It would be nice to have a GTG but I can not commit to a exact time this week. Problably going to try for tommorow night in my own garage. If I had a bigger garage I would have a meet at my place, but I live in a condo.

Can we get a moderator to break this GTG off into a topic of its own?

Seeing as how no one has set a date/time and/or volunteered a place, in a word, no. :P

Well I changed the Tranny and the turret oil last night. It went pretty smooth. It was definitely time. The old tranny oil was nasty to say the least with a little sludge and small amount of metal shavings on the drain bolt. There was a little old oil left in the turret and I am going to have to get a new inner boot due to it having a small tear. The diff oil will get changed tonight hopefully.

After driving the car this morning I could feel a huge difference. Sooo much smoother to shift in all gears.

[channelmaniac]

Cool - Fine metal shavings on the bolt are normal... As long as it isn't chunky, you are good to go.

I'm currently using Red Line but will be switching to Mobil 1.

Just did mine over the weekend with Royal Purple.

I have Mobile 1 in the 99 Toruing and Red line in the 99 Sport. I think Mobile 1 makes it a little "stiffer" in very cold days. Otherwise, they both are "happier" when it is warm.

[trackdog]

I am sure all the synthetic trans oils will work just fine. I prefer Red Line because it has not failed me with the power I run through it, 280 HP. MTL because it is thinner is a little more notchie, but it also robs less power. I prefer the heaver MT90 with forced induction engines, but for NA cars I would use the MTL. Even the rear differential with this much power and extremely hard track use has never failed. That should say something about Red Line oil performance.

We keep it in stock.

I don't think you are "CURRENTLY" using anything
