Hey everybody, I recently bought my first truck, 2012 tundra 4d 2wd with 155k miles (I’ve had many Toyota’s in the past). It seems I’ve run into some transmission issues. I would say 90% of the time the truck shifts almost perfectly with no effort, but I’ve noticed that sometimes going into 3-4 gear around 40-45 mph, it will go into gear and the vibrate for a couple of seconds. The vibration feels like it’s coming from down under and I don’t feel it in the steering wheel. Also, very rarely, it will kind of clunk and lag into a gear if I’m accelerating slowly (gotta conserve gas on these suckers). If I really press on the gas it will give me a light clunk as well. I called a transmission specialist and he told me to come in immediately, but I’m not always keen on auto shops because I’ve had multiple bad experiences. Figured I would come here first. Anybody got any ideas? Any advice would be helpful!!
