Yesterday I filled the Transmission on my 2005 GSR 5 speed with a mixture of 2 quarts if MT90 and one qaurt of MTL at 18,500 miles.


I am very impressed with the mixture. Shift feel is vastly improved both cold(30 degrees outside) and hot when everything is warm.

We'll see how it wears after a few thousand miles. I'll try and remember to post here as the miles wear on.

 

i just fulled my tranny with the same and it feels great

 

I used MT90 in my Nissan for over 100k miles and loved it (changed about ~30k miles).

I'm curious as to why you're mixing MT90 and MTL instead of running straight MT90?

 

your supose to run the mix because it is closure to the stock oil weight than straight mt 90

 

Ive had that mix for 13k miles. I like it alot. Its getting a bit notchy now, but its been great. I just bought more and am gonna change it tomorrow.

 

Straight MT-90 is supposed to be to thick for areas where it gets cold.

You should be able to run straight mt90 and be fine but IMO this mix is just right.

I let a friend of mine who has had both the 5 speed and six speed evos drive my car with the new tranny oil today.

He said mine shifts the smoothest shifting evo he has driven.

And my car shifted absolutely like crap before the change. Notchy as hell. Getting inot gear when cold was an excercise in patience.

 

I have some shockproof heavy and was thinking of mixing that with mtl in the tranny. What do you guys think? The place I normally buy my oils ran out of mt-90 so I thought this would be a nice alternative.

 

Ah... I see. I never had that issue in Texas, Florida, or So. Cal now

After I went turbo in the Nissan, I switched to heavyduty shockproof and had been using that for ~40k miles. SE-Rs like to completely shread 3rd gear when boosted, hence the heavyduty shockproof.

I've only really read of Evo guys using it in the transfer case though. I haven't seen any stripped gear issues yet with Evo trannies?

 

I had used both. I once had problems with the shyncros on my Dodge Stealth R/T twin turbo. I then did an extensive search on www.3si.org and found that the Red line MTL was known to cure the shyncros grinding noises.

For a few minutes after I did the transmiision oil change I thought I was on crack, I couldn't believe how magic this product was. Note I did not use the word good but instead the word magic. This product actually fixes some serious issues that otherwise you and any other transmission shop would had thought that perhaps your transmiision has to be replaced.

Highly recommended(both) MT and MTL

Now contemplating mixing 2q shockproof light + 1q mtl. Insight?

 

So you recommend the mix?

 

I personally will only run straight mt90 now...

 

We are approaching 2 months on the mix and I must say I am still pleased.

Even on those god aweful 5 degree mornings the tranny works well.

NOT as good as warmer weather, say above 30 but I am still pleased.

I have driven 1500 miles so far.

 

where can one buy Redline oils?

 

My friend, djtmotorsports, had been using it on my evo for the past year and my trans has been great with the mix. A couple of track days each year and lots of daily driving for over 30K miles with the same mixture (changed out every 5-10K miles) and I've had no problems. But I would still recommend the Diaqueen for the rear diffs... just on a side note.

Even with the below 0 deg temps we've had these few weeks, the car shifts pretty well. But it's awesome when the temps are just above the freezing mark.
