I don't know if this is such a good idea, but I did it. I have not felt anything out of the ordinary when shifting through the last 10k. Is the 75w110 gl5 safe for my 98's 3.4 manual 5 speed?

Fine idea. 75W-90 or 110 will be good in a Toyota transmission. Maybe MTG would be a tad better shifting, but SVT will give killer protection.

Wicked. Thanks Pabs. The transmission has 193k on it. When I switched the fluid over to synthetic @ 143k when I got it, the input bearing started to buzz. The protection at this juncture, I would contend would be worth the 110 (?) I'm wondering how long I can extend the life of this transmission by using some [censored] good fluid. I have never experienced any shifting issues really. I previously ran Redline MTL and MT90 with good results. The 110 does feel a bit notchier, but solid and steady (if that even makes sense). However, the bearing noise is unchanged. I will be driving to Minnesota in a week from San Jose. I did this last year on the Redline and experienced no issues. It's just this [censored] cheap throwout bearing that irritates me the most. I will never buy a non OE Toyota clutch kit again.
i thought manual yota transmissions required GL-4? i know the amsoil states GL-4 compatable but i would have leaned towards the GL4.. but if you arent having issues then oh well.. if you do, change to the GL4 amsoil
Is it the TO brg or the input shaft brg that's noisy? The TO brg would be noisy mainly when clutch pedal is pushed, Input shaft brg inside the transmission will be noisy in every gear except direct drive gear where input speed equals output speed. On my truck this is fourth gear. Bad or worn/disintegrated pilot brg or bushing will cause the input shaft brg to go bad sooner. I had a bad input shaft brg, and needed better protection to keep the unit together until I had time to repair it, so I dumped in 3 quarts of 75W-140 Severe Gear and it really smoothed out the rattles and noise somewhat for about a year, and kept the unit from self-destructing. I had to take care shifting while cold and actually had to shift faster to the next gear when cold, since the thicker oil slowed the gears down more quickly between changes. After warming up things started to normalize and smooth out. I really liked to feel of the thicker oil in that worn trans. Now that it has been overhauled with new syncros and brg kit, (and input and output shafts had to be replaced,) I am using the MTG and is working perfectly. This was on my 90 Ford Ranger.
The input bearing buzzes when the clutch is not depressed (or that is the conclusion that I have come to after a year of research on the forums). The throwout bearing also chirps like a bird when there is no pressure on the clutch pedal. When I put a bit of pressure on the clutch pedal and the little bump from the slave cylinder seats nicely in the clutch fork dimple, the chirping disappears. The noise is created from the rubbing of that little bump on the metal of the clutch fork. It is extremely annoying. I just wonder if these issues will cause the demise of my transmission and clutch, or if it is ok to drive on for another 50k or so....Any ideas guys? Any ideas how to grease up that spot on the fork or the innards that will allow for a quiet to bearing? I have tried unsuccessfully to quiet both bearings. Anything helps.
I have that same issue on my 2002 Tacoma with 3.4 and 5spd. Chirps like a bird until you put pressure on the clutch pedal. I can only hear it in Neutral though.
I figured it wasn't the TO bearing, since the TO bearing doesn't do anything until you push the pedal in, thus "throwing" the bearing out, I have only ever heard them make noise when you "throw" them out, and they are getting old and make noise. I didn't know they were even spinning unless they were out against the pressure plate.
Is it the bearing itself that makes the noise or that it rubs against something else and makes noise?
I agree it is pretty annoying though.
