I know the trans is old and has had its share of wear and tear, but when I first start driving and the trans is cold (I'd say about 50-70 deg F or so), It shifts like butter in every gear, including 3rd, of course. That's the only thing that's giving me hope that my 3rd gear grind can be remedied somehow.

It just seems like it could use something thicker, although I wouldn't want to use something too thick...

No...nothing you can do, pretty much, all you can do is rebuild the tranny. I'm at that point, tried running thicker oil, it kinda helped for a bit...3 weeks later, im back to the same point. Its getting so bad that i have to double clutch to get into 3rd without it grinding. Ill probably toss in my spare tranny and have the one in the car rebuilt.

I have to do the same, only when I'm on the throttle and shifting quick though. In normal cruising, if I shift from 2nd just right, sort of slowly, then strong into 3rd, I can get it in smoothly most of the time. But just shifting with a 'normal' force into 3rd will almost always cause it to grind.

What kind of thicker oil did you use?

Does your trans also shift fine in all gears when its cold?

nismoskyz · 05-08-2009, 01:04 PM

"75W-90" means the viscosity is 75 when its cold and 90 when its hot, right?

So if my trans is shifting better when its cold than when its warm and since 90 is a thicker weight than 75, wouldn't that imply that I need a thinner weight oil? Something closer to 75?
That doesn't make sense though, I would think something thicker would be necessary.

Someone care to explain?

slider2828 · 05-08-2009, 01:40 PM

Yes you are correct 75W-90 for heat, BUT... 90 is usually when it gets extremely heated... It doesn't vary too much.... Any thinner oil might not protect as well and cause further damage. But then again I heard people putting 30W motor oil in SR tranny's no problem.... Oh wellz...

nismoskyz · 05-08-2009, 08:13 PM

hmm, idk, i just want my trans to shift smooth short of rebuilding/replacing the thing!

ro240sx · 05-08-2009, 11:17 PM

I finally changed my tranny oil with redline mt90 and its great. It got rid of a small 2nd gear grind and its make shifts smoother.

*fliprayzin240sx* · 05-09-2009, 07:34 PM

I had 75-90 oil in the tranny, poured some out and added a quart and a half of 75-140 to thicken it up. It helped a bit but not much, it still grinded and felt notchy as fuck trying to get into 3rd.

hmm yeah thats pretty similar to how mine is. It's not too bad though, and still feels better than the RP I had before.

I'm thinking about mixing in a quart or two of severe gear 75-140.

When you say "notchy" what do you mean? Like grinding, or the oil was too thick?

rsibley22 · 05-25-2009, 02:45 PM

after running amsoil in my sr it got rid off all the noisy lifters will always buy amsoil from now on super happy cant wait to try the trans oil

*fliprayzin240sx* · 05-27-2009, 06:46 AM

Well I decided to pour out all the Royal Purple Oil and found some regular Quaker State oil, surprise surprise, tranny runs better. But its too late, I got hella shavings from running Royal Purple. SO my advice to everybody....DONT RUN ROYAL PURPLE TRANNY OIL!!!

Cliff Notes:
Got my car back from getting engine rebuild
Didnt know what tranny oil was in it so I swapped it out for RP 75/90s
Couple of days later 3rd gear starts grinding
Noticed that it runs better when tranny is still cold
Figured thicker oil might help so poured out half of the RP 75/90 for some 75/140s
Didnt make much difference
Poured out the Royal Purple Oil out
Swapped in regular gear oil and runs fucking better

HYPNOTIK · 05-27-2009, 10:49 AM

Ray, I'm running the Quaker State bullshit from the gas station right now and it seems really shitty when it's cold. Anytime I let it sit for more than 10-20 minutes and get back in it it will grind 2nd every time no matter how slow I shift. I was considering swapping to a RP 75w90/140 mix but it seems that hasn't helped you either. Have you found anything else on island thats worth a shit?

nismoskyz · 05-27-2009, 02:04 PM

^AMSOIL 75w90 is pretty good and, although it didnt solve my 3rd-grinding entirely, is still a huge step up from the 75w90 RP I was using. I'm thinking if I try a 75w90/140 mix of AMSOIL, it might do wonders...

slider2828 · 05-27-2009, 02:14 PM

Hahha maybe..... I was thinking that too. Severe gear oil + Tranmission oil... It sounds like a good experiment..

nismoskyz · 05-27-2009, 02:21 PM

exactly

hopefully it wont break anything. i figure i might give amsoil a call and see if they have any input on mixing the oils.

slider2828 · 05-27-2009, 02:51 PM

Just in case you missed it, I had it in my tranny ahahah and removed it and put the transmission transaxle oil in it. I am sure I didn't get all of that shit out, so far not a problem. But have like 1 qt of it, I don't think its going to mess with anything hahah.

gsxr141 · 05-27-2009, 03:12 PM

i used a mix of 2 qts regular redline fluid and 1qt of redline shockproof. seems ok, but i still hear the synchros sometimes when i shift into 2nd.

I had the same experience, I tried redline MTL and I was much happier.

Here you guys go to confirm what everyone has said....

http://www.synthetic-oil-tech.com/Ge...te%20Paper.pdf

This was an independent test of gear oils, of course this was not the test of the GL-5 Sever Gear oil, but I have ran it I with 3 full course track dayz and it worked fine.... But no surprise Amsoil came out on top. Also the Amsoils Sever Gear oil is GL-5 rated, but as seen in the materials test, it exceeded GL-4 standards with great protection for copper and stuff. Royal Purple straight FAILED!

O and I read on Amsoils site, you can mix the severe gear oils with other oils. So I am going to try and mix 75-140 Sever Gear oil .75 qts in there.... So a total 1/3 Sever Gear oil 2/3 Transaxle oil.... I think this might be the best result.

******** EDIT **********

Get Amsoil at dealer prices for 6 Months https://www.amsoil.com/Amsoillogin/p...aspx?zo=401037

Basically pay 10 dollars and fill stuff out and get major discount on all Amsoil products.

Honestly Casey...I have no fucking clue at this point. AAFES decided to run nothing but RP shit. Last time I went to FHS, they had some AMSOIL stuff, but they didnt have tranny oil, they only had gear lube (didnt get it cuz I thought its only for diffs 80-90W). At this point that would be better than anything else we can get our hands on.

I ordered some oil from AMSOIL but shit, been over a month and still nothing. Im thinking it got pinched and got sent back by APO for having HAZMAT or some shit like that.

Bigsyke · 06-01-2009, 01:30 PM

Ive been about 3k miles on the amsoil GL-5 75w90 gear oil (FGRQT-EA) Fully synthetic gear lube, (not the MTG which is GL4).

Still no grinding, its good stuff. Im ordering the MTG now.

If no problems, why switch to the GL4 now?

slider2828 · 06-02-2009, 06:12 PM

I ran both, and it really feels similar.... Good luck guys, but sounds like your are on base somewhere, and if it is like overseas, pretty much customs will get it before anything...

slider2828 · 06-02-2009, 06:14 PM

AMSOIL SEVERE GEAR® (75W-110) provides superior performance and replaces competitors’ 75W-110, 75W- 90 and 80W-90 gear oils. It delivers better viscosity protection than SEVERE GEAR 75W-90 and better fuel efficiency than SEVERE GEAR 75W-140.

AMSOIL SEVERE GEAR® is compatible with conventional and synthetic gear oils. Mixing AMSOIL gear oils with other oils, however, will shorten the oil life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed. Aftermarket oil additives, other than those specified by AMSOIL, are not recommended for use with AMSOIL gear oils.

*fliprayzin240sx* · 06-03-2009, 01:08 AM

Would AMSOIL's 80-90W GEAR OIL work for tranny? Then again who cares at this point since Im running Quaker State Gear Oil, again...cant find Tranny oil out here other than RP. If I try to get it off base, Im lookin at $25 per qt of regular crap. Even then still cant find GL4, theyre all GL5s.

kevmeistah21 · 06-03-2009, 01:32 AM

soo i just bought mt-90 and put it in and on cold starts i can't put it into gear.. what could this be?

slider2828 · 06-03-2009, 09:34 AM

Nothing, MT90 Sucks..... THat is why. Cold grinding is part of MT90, why you ask cause I tried it and that is what happened. Its junk.... Wait till the car is warmed up I bet you can put it into gear then.

I tried it Amsoil 80-90, worked great. Not much difference than the transaxle in my test. Can you try a 80-90 with a 80-140 75%/25% mix? I just wanna see if that helps. But I tried exactly 80-90 worked great.

yea i noticed that right when i put it in.. takes me 15 mins before im able to put it into gear... :/

slider2828 · 06-03-2009, 04:46 PM

Like I said, drain that shit..... put god forsaken cheap gas station gear lube and it runs better than that....
