First post to this board.

I tried searching the archives, but have not found any posts wrt to recommended tranny fluids.

I'd like to use Mobil 1 tranny fluid, but don't know which weight to use.

Anyone have recommendations on tranny fluid?

Honda MTF, if you care about your car.

It depends on what you're using it for....if you are going to road race, then Honda MTF will not hold up with the heat....in which case you'd need a synthetic like Redline in your tranny.

If you are just driving it on the street, then Honda MTF will do just fine.

There are reasons guys get grinding and breakdown with Redline...it's because it's not made for a daily driver, it's made for high temp high demands racing.

People who get grinding with Redline, are using it for the wrong reason. Same with GM synchromesh...all the hype regarding that....if you are a daily driver, get Honda.

If you are on the track, get Redline.

Break down cause it isn't raced? Dude, come on. Redline is a good brand wether it is streeted or raced. The Redline additives don't work well with our LSD and racing won't hep that. Some report ill effects others don't.

GM synchromesh is suspect for me at this point but I will report more later. I won't elaborate till I have more proof.

Honda MTF is in hundreds of Type-Rs that all go on track. I have owned 2 R's and both have have been on and off track with only Honda MTF. It doesn't break down and does very well.

Many thanks for the input.

Here ya are...from the man who has taught me everything basically....Micahael Delaney from Team-integra.net...aka Tuan...

"you have to be careful about making blanket statements.

it really does depend on the operating temp. range people are dealing with.

if you're in a high heat scenario doing a lot of weekend strip action, one lubricant made for one kind of use will become putty under a strained condition.

I'll give you an example:

we had been discussing gear oil for for trannies with clutch pack LSD's.

most people base their choice on the GL rating and API rated weight.

in some cases the operating temp of the gear oil designed for hard high heat racing applications were being used in street daily drivers. These oils were too slippery for the daily driven cars with LSD's and the clutches in the LSD would not grab...no LSD lock up when you need it. People then needed to add friction modifiers into these racing gear oils to get them to allow the LSD clutch surfaces to grab. Other people got cheaper gear oil that weren't made for racing and then found that the clutch pack grabbed better during daily driving. Did that mean the cheaper non racing gear oil is better than the racing gear oil? Of course not. One track day with that cheaper oil and the clutches in that LSD would be toast.


SO was it a case of bad gear oil or improper choice?

If you high rpm launch your car and powershift, is it fair to ask an OEM MTF to handle the heat you are generating?

This is why we need to be smart and start looking at what factors make a product good and under what conditions before we announce how great they are. It's about educating each other. It takes more work and digging and less superficial assessments. That's why it's so much harder to see these kinds of review. People have to get out there and get the facts and put it together. But in the long run you understand better. You understand WHY something is better. It's not an intuitive thing. When we don't know all the info, we rely on intuition and that works sometimes. But it'd be nice to link intuition (right side of your brain) with logic (left side of your brain) and have the 2 working together in nonduality."
