Just had Toyota fix my auto tt and i picked it up this morning to find that my trans isn't down shifting. When i put it in drive it up shifts all the way to o/d at the minimum shifting speeds when im flooring it. It won't shift to low unless im at almost a complete stop and isn't kicking down in any gear. Its definetly going back because it worked perfect b4 i took it in. Anyone know what could be causing it?
