Transmission whine

I have a 2007 Tacoma PreRunner Double Cab, 5speed Auto Tranny, with 95,000 miles one it. Last week it started to whine, very similar to the transmission sound you hear when you go at a higher rate of speed in reverse. When you slow down the whine continues (just like when reversing and you let off the gas) but slows to match the engine, same with acceleration.

Any thoughts?

Thanks!

 

Check the diff before assuming its the tranny. Does the noise change noticably when the tranny shifts? Or simply with speed no matter what gear the tranny is in?

 

I've had the truck serviced every 5k miles at Toyota since I bought it. The noise remains constant regardless of what gear the tranny is in. However, when I shift into neutral the noise stops.

 

In that case, it does sound more like the diff.

 

Could also be a pulley.

 

Thanks for your good advise everyone. Turned out it was the differential. Rather than pay the $2400 to have it repaired, plus it's time to do the brakes and replace the tires, I opted to trade it for a 2012 Tacoma Double Cab Pre Runner.

My fiance thinks it was so strange that I go to the dealer and come home with the exact same truck, only a 2012 instead of a 2007. Same color, trim pkg, etc.

Oh well, what can I say? You can't mess with a good thing!

Thank again folks.

 

Very nice, decision!

 

Smart decision.If you would have put $2400 in repairs plus $600 to $800 in tires plus brakes you would have at least $3000more in your truck and it would not be worth a dime more.

 

just curious...how did you make out as far as trade-in value on your 07?

 

Actually I did pretty good. The KBB for "Excellent" was $15,535, but since it required the work they gave me $13,500. I was happy with the deal, especially since I only had to finance about $15,000 which kept the payments low for 4 years.

 

Shit. I think I have this problem...

$2400, that sucks.
