My transmission on my sr5 4x4 is absolute dog poop. Constantly slamming gears, jerks, bucks etc. I went to check the transmission fluid which requires you to pin the thermostat. I don’t have a thermostat. I went to the dealership and looked under a bunch of Tacomas and 4Runners and they all have transmission thermostats. The dealer didn’t have any sr5 models but I looked at TRD OR and a limited and they have thermostats. Did they forget to install one at the factory? Can anyone with a 4x4 sr5 take a look at theirs? Thank you
