    I have had my 09 Taco since Oct. '08. It is the 2.7 auto Access with 14k miles. Recently I have noticed a minor noise/vibration when it upshifts or down shifts at minimal rpm and usually at 20. 30 and 40 mph. It is like a 5 seconds of "Brrrrrp" noise with minor vibration. I don't recall it doing this until recently. It doesn't do it at higher rpm.

    Am I hearing stuff or might there be an issue here? I bought it new and is still under warranty.

    Any info would be appreciated.

    Not sure if this helps- It applies to 08 and older Tacomas.

    I noticed that yours would be a very early 09, so see if your VIN number qualifies.

    There is a TSB for "Driveline Vibration between 15 - 25 MPH"

    TSB-0132-08

    For inline 4 cylinder models 2WD your VIN would have to be earlier than 5TE*X##N*8Z499787

    The *'s and #'s are wildcards so the actual digits don't matter I believe the last 5 or 6 digits are your individual serial number and should be sequential- eg. see if yours is a lower number then the TSB applies.

    ^^ check out that TSB, and also their is a Tranny TSB from what i hear that is a reflash and helps make the shifting better.
