Toyota Tundra Transmission Problems
I was stuck in the snow in 4wd high, then tried low, to no avail, tried the tranmission in lo (which didn't engage--just 'lo' light blinking and alarm buzzer, then tried 4wd HI and there was NO transmission response, a grinding in "P' and no low, high, or anything--from Park to D, Reverse, all the gears were gone, and I was getting ready to call for a tow truck, and after grinding the P gear for a while and back into N, it went into 4wd high.
Toyota replicated the problem, after some doing, and they're trying to fix it as the 4wd acuator is a problem--it's backordered to Japan which means the truck is out of action for a month.
