My 07 Tundra 4-low isn't working. It shifts fine into 4-high. When I shift it into 4-low, it just beeps at me. Any typical problematic areas to look for? I hate push button, 4-wheel drive systems.

The truck is still under warranty, so I can go in. However, I would like to know more about the Tundra's 4 wheel system works and how it actuates the T-case.

Thanks,

 

are u at a complete stop ?

 

are you in neutral

 

besides those two conditions listed previously, you have to shift from 2wd to 4Lo without stopping at 4Hi. I had the same problem with my '03 4Runner.
and make sure your'e in the dirt, otherwise you'll bind up the tires big time!

 

Yep, I am following the basic procedure layed out in the manual. IRC, you come to a complete stop, shift to nuetral, then put it into 4-low.

My dash then procedes to beep at me endlessly, and the T-case does not go in 4-low.

I am starting to learn more about the truck. It looks like the tranfercase model is the JF1A. I am still having a hard time pulling any info about it. I will keep searching.
