Yes, the 4wd Tacoma regular cab is available with a 4-speed automatic transmission. That configuration can be found new or used. I've seen more autos than manuals in them.
**The table on the website is a little confusing. The link has the regular cab 5-speed selected as a default. To change it to an automatic, click on "change" just to the upper left of the little picture of the truck. Then you can select the different configurations.
An automatic transmission is available in every Tacoma configuration except the current X-runner, the 2wd sport/performance variant.
**no worries, RyD
