Question

the truck has 3 codes p0751, p0776, p2714 its a 2009 Tacoma prerunner 2wd

Answer 1

all 3 codes are related to the transmission, if you are under warranty I would take it to the dealer if not I would start by replacing the transmission fluid. drain the transmission fluid in a clean container so you can see if there are any metal shavings or metals in the fluid. Also if the transmission is shifting hard the transmission might be bad
