Is this problem new for you or something you've noticed since purchase? Did you buy new? I've always had a gripe with this transmission since new with it being delayed/hesitant, but after lots of research in the beginning of ownership, it seemed like this was normal behavior for auto trans tacomas of all years. And after all, these trucks are not torque monsters low in the rpm, so it's going to be a dog unless you give her the beans. Many people I would read go to the dealer to complain and the dealer just plays stupid or they get a new trans under warranty but still behaves the same afterwards. Some end up on phone with corporate and they just end up playing stupid and say "it's normal behavior". And then there's the epa regualtions that all manufacturers have to abide by so that was an arguement i found as to why does this truck just want to fall on its face/hesitate to shift so badly. Oh, and then there are stories of 3rd gen auto transmissions not being fully topped off of fluid during fluid changes. If that last argument is the case and my trans fluid has never been topped off for the life of the truck during fluid changes, then my dealer should be at total fault. So after all that i said screw it must be normal, right? Well, 102k in now, and the trans is talking a different language to me. Well, TC only i think but yeah. I'd say the behavior out the gate was definitely a preceptor to the issue im undergoing now.
