I SAW WHERE A PERSON WAS RUNNING RED LINE MTL FLUID IN HIS VEH, -BUT GM CALLS FOR A GL 5 FLUID.--I currently have red line that is 75-90 GL5.Snth--- So do you think i be better off with the GL4 APPROVED FLUID OR KEEP the redline GL5 i just put in in it. ?? -I saw no diff with my shift aFTER adding new redline 75-90 GL5 Syn.---Im a v6 manuall.---Veh has 4,000 mile on it and has intermit gear clash [slight],----------,[ sorry for the cap's ] -- Also Would love to get rid off all the noise this trans makes going into gears [not gear clash]

I've never been a big fan of Redline, but alot of people are. Many on this site swear by Royal Purple, but the slipperyest stuff I've ever seen is a brand called Motul (Motul 400 i think, GL-5, 75/90 full syn for manual trans) but like you, I saw only minimal improvement over stock.

I think we just need a new transmission!

Mine got better after Royal Purple Gear Max. I put it in the tranny and rear diff. Tranny still not perfect, but better.

I am almost positive that the shifting issues are more due to the clutch not the transmission itself. I have issues putting my car into second gear at a stop light but if I hold it where it gets stuck while slowly releasing the clutch it falls in.

carls2010 · 08-01-2011, 07:15 PM

YES, I tried the red line 75-90 and saw no diff in my shift.--i just get just a slight gear clash,,- now and then from the AY6.--So i took that fluid out, and went with red line MTL 70 W 80.- This looks like trans fluid but is for trans's.-And it is syn, and a GL4 CLASS.-In which i saw the cadilac used, that a few years back.- Ive only driven car 20 miles prior to posting this - and WOW SMOOTH SHIFT,,And it cut down on the noise level of actually putting in gear. Ill keep you posted

carls2010 · 08-02-2011, 07:16 PM

yes after doing talks with trans guys who have rebuilt these and other GM manual trans, --it comes down to the AY6 needs transaxle fluid, NOT GEAR OIL !!!! - AND ALL THREE SAID SAME THING right off the bat when i told the gear clash going into gear,,, get the gear oil out and add, synthetic trans axle fluid ,,example would be RED LINE MTX.-- It LOOKS LIKE automatic fluid but is not.---Mine is getting smoother by the miles just like trans guy said it would. ----P.S. --- WHEN GM ADDED THIS TRANS to the cadilac it orig used this type oil -GL4 RATED.- Wonder why they changed

I would be careful changing to any fluid not GM approved. It could be a basis for warranty denial on your tranny..

xpanda305x · 08-02-2011, 07:30 PM

In the owners manual

carls2010 · 08-02-2011, 07:48 PM

the red line # i used is 50204.--AND if anyone still complains about a gear clash at all or hard going into most gears ? oh well then, keep your rear end fluid in there.- P.S. - I work at a chrysler dealer and we had had issues over the years of same thing with manual trans that orig had a rear end gear oil in them.-Now they run on tranaxle fluid like i posted .-mmmmmmmmmmm

You might be on to something there!

Ventmaster · 08-03-2011, 03:09 PM

Carl, this could be a very expensive experiment!

But you've got me thinking....I'd try about anything to improve the trans-
it ruins my enjoyment of the rest of the car.

I thought the shifter was the problem, turns out the stock shifter was just
a very good disguiser of the real problem: the synchro's or maybe the whole transmission.

carls2010 · 08-03-2011, 04:11 PM

yea, but is a hell of alot better.--- wonder why when gm orig used it on the cadilac it called for a gl4 rated fluid not the gl5 ,,mmmmmm- Also i just put complaint in to the NHTSA, AND hoping others will ,---enough of our whinning ,,and posting issues,-- lets do something.-- gotta call gm now.-- number in owner manul --- P.S. I think the v8 manul trans guys run the tranaxle type fluid [stock] that looks like tran fluid

c_LoW29 · 08-04-2011, 10:36 AM
