Could my tranny be going out?

The noise started when I left the Pismo Jamboree last month or so. The whole weekend I was driving around in low or second gear. Once I got back on the freeway to head home the noise came about. I pulled over and me and the people that where with me looked at my truck and we thought that it was just a wheel bearing. The thing is that i only get the weird noise when I am on the gas and only while driving... If I am not in gear the noise is not there at all.

Any help would be great.

Thanks guys, Bryce

 

Wheel bearing makes noise when the wheel is moving, no matter what gear you are in, or even if you are NOT in gear and coasting. And since you are in NorCal, if you've ever heard the BART tracks, that's what it sounds like. Like you are riding on BART tracks.

 

Yea I had them go bad in my old truck. Thats why I thoughts thats what it might have been... But now I noticed its only when I am on the gas. So i am kinda at a loss my tranny has fluid and is shifting fine just like it always has so idk what it can be.

 

What kind of noise are we talking about?

Is it a whining noise?

 

they best way I can explain it is that it sounds like a really loud tire noise. My tires are not the noise though cause they are not that loud and when I let off the gas it goes away and then I can hear my faint tire noise

Exactly!

 

Hmm... shifting is fine you say?

Is your radio off? I remember a long time ago one my first car had interference and a whining noise when I stepped on the gas. Something about the spark plugs or whatever interfering with the radio. *shrugs*

 

last time the tranny was flushed? ever drop the pan and clean the filter? (assuming these transmissions have that type of filter).

 

that is alternator interference caused by the installer running the signal wires too close to the power cables for the system. That is a possibility but it would also do it at a stand still reving the engine.

 

Have you verified that it is nothing with your driveline? Greased u-joints, etc...?

Yea I thought the same thing cause I heard about this but it was not the radio.

 

I did the tranny not to long ago.

Hmmm never thought of that sand could have dryed it all out.

 

bingo, grease the zerks on the u-joints ASAP

 

Ah yes!! I learned something new today!! Thanky!

 

Grease those zerks ASAP dude!

I would also get it cleaned up as much as possible. Especially with the sand you mentioned.

Fink

 

no prob Hours of research when I was deciding on a head unit taught me that one lol

 

Note to self: Keep sand away from zerks.

Heck. Keep sand away from entire truck for all that matters.

 

Second note to self: Google zerks


*off to google zerks*

 

Ever since I grenaded my driveline on my '95 4Runner...I pay very close to attention to it.

Sand and mud scare me now.

its not so much the sand as much as it is simply keeping those things lubed up. Every oil change (5k miles) for me seems to work.
