This entire statement is ridiculous. Flat out ignorant.

Ashton, this thread has been here since April 30th. Basically for 3-months.

And I would have started a thread as well given the circumstances.

Despite your experiences, folks have been using MT90 in our trannies for a very, very long time with no issues. At one point, it was Mike K's favorite fluid, by a wide margin. It does not go from "the best" to "crap/junk" overnight.

Whether MT90 is not the best fluid or not is not even the issue.

A whine he can hear over his exhaust? That is loud as hell.

Half the money back, and paying B13-tranny money for a B15 tranny is stepping up. But I would not want to pay any money for a tranny that is whining off the get-go upon installation. Not a dime.

After the swap of the stacks he used mobil 1 75w90 and everything was fine, no whinning, no problems shifting, raced it many times without problems.

This means nothing. He was racing and abusing the tranny with MT90 in it. The tranny broke, probably due to the racing/abusing. You swapped the stacks and changed the fluid, and the issue went away. So was that due to the re-build and new stacks, or did the issue go away because of the fluid change? I could easily assert that the issue went away because you put in new stacks, and it had nothing to do with the fluid.

Further, it did not take me 3-minutes to find folks on the internetz that disagree with you completely Ashton. 180 degrees.

I could post threads for days that discuss the tranny fluid. Tranny fluid is NOT the answer for a whine you can hear over the exhaust. Sorry, blaming the fluid is bogus.

I'll take your word for that.

I don't race nor abuse my trannies. Never have. A road-course once a year, where I don't do anything stupid with my tranny, and that's it. No stoplight to stoplight. No speed shifting or shifting without proper use of the clutch. No nothing that could remotely be construed as abuse.

I don't buy parts on the forum and assume that they have previously been (in your words) raced/abused.

Fair enough.

Yes it helps get the most power to the ground because of its high viscosity and low friction but it also causes wear and whinning. Put some conventional or some other synthetic fluid in there.

I've been searching for 30-minutes trying to find something, anything, that backs up your assertions about MT 90. Cannot find anything, any article, or anybody that agrees with you Ashton.

Amazon.com: Customer Reviews: Red Line 50304 Manual Transmission (MT) 90W Gear Oil - 1 Quart

49 Customer Reviews.

43 5-star ratings.

6 4-star ratings.

You can laugh if you want, please find me some empirical data that says that MT 90 is "thin as water", "junk" or "not good by any means."

Is there something better? Possibly.

Is MT 90 crap? That is your opinion sir, and an opinion that is not shared by very many folks, if any.

Can you please show me some evidence that MT 90 sucks? Testing, analysis, comparisons, anything? Hell, I'd settle for some highly educated opinions that match yours. Because I cannot find anybody that agrees with you.

I am not taking sides here between you Ashton, and Jay, on the satisfaction level of this Sale.

He wanted to try to make things right since he says he didnt know the trans had problems.
I think thats a cool thing to do,in fact he wanted to give me more,but I refused since he was working with me on this.

Seems like Jay is done with this topic? Jay is satisfied to the point of not accepting any more refund money? It certainly appears that way.

However, the real question here is NOT the damn fluid. If it is a reputable brand GL4, and new fluid, with a properly working transmission, it should NOT be whining no matter what name-brand GL4 is dumped in the case. Period.

The real question is did the Seller make good with the Buyer, after the tranny was discovered to be whining upon installation? Did the Seller do what he could in good faith to make it up to the Buyer? Is both the Seller and Buyer satisfied with the end final result of the transaction?

From Jays last post quoted above, it certainly seems that way.

Good luck to you both.

I changed my box from unknown fluid that came in the car when I bought it to MT90 a while ago and my gearbox instantly began to whine, and felt very sloppy/notchy shifting gears.

I drained it out and put in some different cheap fluid and the box was silent again and shifted beautifully.

That's my experience with it.

Try some different fluid see what's up, put in the same fluid your buddy is using.

I didnt see the original date of the thread. Again I appologize for restirring stuff up but this was my very good friends trans that I personally have driven his car many many times with it in there and also the pedal work is my work. So im just defending him and my own work.

Again im sorry the pedal welding isnt up to your standards but again converting the cars clutch to hydraulic is not a bolt on affair and I worked with what I had.

As for the gearstack swap to fix a problem, the main problem was not the whinning, it was 3rd gear grinding heavily going in and popping out of gear unless you hold it in. The gearstack swap solved that problem and with different fluid in the trans the slight whinning there was in 4th and 5th at higher speeds was completely gone.

Again eggman, sorry to stir things back up. I mainly just wanted to put my own personal experience with the parts out there.

Its been worked out and im glad. The trans isnt going to just blow up on you either. Reading the posts about that is funny. There are a lot of things that can cause a whine, too thin of fluid, improper gear/diff alignement, worn bearings. That doesnt mean its going to just grenade. Matter fact it probably will never grenade unless its a bearing problem. But using a thicker fluid than mt90 will again probably take the whinning completely away and also extend the life of the trans.

Dang. Had a '96 Alti that whined a lot, was bad enough to keep eating axle seals. Case flex? My LSD B15 tranny never whined. Bought a '00+ LSD P11 tranny from a forum member for my '99 g20, had a blown ring and mating gear. Besides the obvious crack in the bell housing I had to fix myself. The stack and ring gear he provided me with as a replacement seem to whine in 3rd and 4th almost as much as my old Alti, but no leaks just a little sloppy on the 3rd gear syncro.

My transmission started whining then BAM... It started locking up in gears... I used mt-90 and the transmission worked flawless until maybe just a few months of running mt90... Just sayin...

GM synchromesh FTW for the B15 tranny BTW. Only time you get issues with the B15 tranny is very long highway drives, the input shaft bearing gets oil starved, that killed my bearing. Easy repair. Worked flawless after replacing it with a new OEM NGK bearing.
