    Hi TW,

    We picked up a 4 cyl 2WD automatic Tacoma for farm duty last month (See http://www.tacomaworld.com/forum/2nd-gen-tacomas/100180-our-new-farm-truck.html ), however a small issue has come up just today which has me puzzled.

    When slowing down to a stop on any terrain, when the truck shifts down from 2nd to 1st, there is a very noticable vibration/rumbling that last about 3 or 4 seconds (depending on how fast you're coming to a stop). It feels and sounds like you're driving over a highway rumble strip.

    Had this truck almost 4 weeks now and first time I've noticed this. Asked the other workers if any of them had noticed it, and no one had.

    Truck has 34 miles on it.

    Thoughts?

    Figure anything out yet? It's a 2wd regular cab, right? So, no carrier bearing to worry about...

    I have this exact symptom on my brand new V6 Double Cab. Anyone heard of this or know what it could be. My truck has done it since day 1. I have 300 miles on it.

    Thanks
    Greg

    Hi Greg, we did indeed figure out what it is. It is the rear transmission mount - it's flexing and allowing your driveshaft to go to an improper angle. There is a TSB out to correct this problem. Ask your dealer.
