All of the 2005-2006 Tundra trucks fitted with automatic transmissions apparently had a poorly designed transmission mount installed from the factory: tsb-0067-09.
Like many owners, I reported sporadic clunking noises coming from the chassis under the driver/passenger seat area during all service visits and as the basis for one specific service visit back in late 2009 with 37,000 miles on the truck. In every instance, the tech "could not duplicate" during a test drive. On the 37,000 mile visit I rode along with the tech and after duplicating the noise, they were unable to diagnose a cause, but noting it was "just one of those things" with these trucks.
I foolishly learned to live with the condition which was very disconcerting at times, but very sporadic.
However, in December 2014 with 106,000 miles on the ODO I discovered that the pinion shaft bearing on the rear differential had failed and was in need of replacement. When asked if this was "normal" the answer was, "it's not all that common but it does happen". The repair cost was estimated at $1,200 as the recommended service include replacement of the entire "acorn" assembly. However, it wasn't something that my dealer or another shop felt had to be addressed immediately so long as we weren't bothered by the noise.
In doing my research on the pinion bearing failure I discovered that there had been TSB issued by Toyota in Feb 2009 for the very same clunking sounds I had reported to my dealer at 3 years / 37,000 miles. The TSB extended the vehicle warranty to 6 years / 66,000 miles and covered the replacement of the transmission support bracket, cross member and hardware, using "an improved" transmission support bracket that eliminated a large rubber bushing in the original design.
While I have no idea if the faulty transmission bracket may have contributed to the pinion bearing's premature demise, noting that I have only used my truck for light-duty towing (motorcycles) on four occasions / less than 1,500 miles at 95% freeway speeds, I am more than disappointed that my Toyota Service Advisers at Cobb County Toyota failed to extend the repair authorized by the TSB "upon customer reported complaint of chassis noise" while it was in effect.
I've since ordered the parts called out by the TSB from a Toyota dealer in Boston, MA, that offers clients less than MSRP pricing and will install them myself when they arrive.
p2715 faulty slt solenoid 8 mo aft tran 'flush' by dealer
2006 Toyota Tundra 4.7 Double Cab. Always use Amsoil and Fuel Tech additive at every fill. In June 2014 my transmission was occasionally clunking at a stop 93,000 miles. Went to Toyota Dealer and they recommended a Transmission "Flush". I had been advised "never" to flush a transmission because it can stir up sediment that could clog up the tiny parts inside. Just drain and fill. They flushed anyway. Clunking ceased. March 2015, sitting at a stop light, pressed accelerator to proceed and no power! Finally crept through intersection. Called hubby and he walked me through a trouble shoot. Put vehicle in neutral and pressed accelerator. Varoom, Varoom. In drive still no power. Got it to dealer and did a P2714 Fault Tracing.
100,868 miles Faulty SLT Solenoid. Part only available through Toyota. Dealer replaced Solenoid for $582. Checked internet and found that Faulty Solenoid could be caused by trash clogging unit! Coincidence?
Found slight leak in Tail Shaft Housing. What next?
