I have a 2006 Tundra V-6 and noted there is no way to check my automatic transmission fluid or to even add transmission fluid. I did see a drain plug and an odd looking plug to its right at the bootm of the oil pan that appears as if it can not be removed. How do I check my oil level and refill with a fluid I want inthis tranmission? Please e-mail me. Where can I buy the specil tools and plugs to this myself.
