Automatic slow down at 30mph. Transmission issue?
 

Just bought 2006 SR5 with 44600 miles. When coasting and the speed hits 30mph the car automatically slows down. it feels like the brakes are put on...Transmission issue? dirty fluid? time for a flush? thanks for any help

Sounds like the tow/haul or the engine brake that i believe these models have. Its a button that you depress to act and deactivate.
