Manual Xmission Noise -- '96 4Runner 3.4L V6 4WD

pizzabob · 11-20-2009, 10:44 AM

Last night I began noticing a "swishing" noise in 3rd and 4th gears. It goes away in neutral. When I wiggle the shift lever, particularly in 4th gear, I can hear the volume of ths noise change with the wiggles. Started out barely audible and now I can hear it over the radio.

I'm assuming this is likely internal bearings wearing out. Would you folks recommend, say, a Lucas product, to mix in with the oil? Which, by the way, I changed about 3 years ago. Vehicle has 270K miles on it.

Thanks for any help!!

maybe a throw out bearing? Does pushing the clutch in effect the noise?

Hi, C Pizzle, thanks for reply -- No, it has to be in the xmission since wiggling the shift lever changes the noise level. And clutch engagement/disengagement does not affect it.

A change since my last post -- I can now hear the swishy noise even when coasting in neutral, as well. And it always ceases when I stop rolling. Would that tend to indicate a bearing leading to the drive shaft, since it seems to be related to road speed?

One local transmission shop I just visited quoted a bearing kit at $578. Hello -- I think I would go find a used tranny before I paid that much for the stupid kit, no??

yes I would likely go for a barely used tranny if you can find it.

cpizzle you are a Limited with a 5 speed? I thought all Limiteds were automatics?

try replacing the shifter seat bushing in the shift lever. i had a whine in 5th gear that went away after i replaced it. they're only like $20 to replace both the shift seat and the socket. so if it doesn't help, not out alot of money and it might save you a transmission rebuild.
here a writeup and more info(done on a 90's pickup but they're all the same)

x2. i thought the 5sp was only offered in the SR5/base trim level (with 4x4 offered in all packages)

sounds like those shifter seats may help, pizza- in fact, i'm bookmarking that now as one of my future projects.

Maybe you guys are right? I could swear mine says limited on the back of it?? Haha I am embarrassed I dont know....

Thank you, 3w4Id -- I'm going to give it a try. I just replaced the oil and laced it with 50% Lucas treatment, with absolutely no change in the noise... I would've thought that the thicker oil would make some small difference. Since the shift lever seems to modulate the amplitude of the noise, what you posted makes a lot of sense.

Couldn't hurt to give it a try!!

Gotta go to bed... getting late... full as a tick... We had pizza tonight for dinner, as usual...
