Question about 2007 Toyota Camry
Hi. I am the owner of a 2007 camry LE. And let me tell you, i still experience the same behaviors with my car as well. The erratic 30-40 mph shifting is either up or downshifting due to the innovation of the ECT-i (Electronic Controlled Transmission with intelligence) meaning the car has two ECUs, one for the engine and one solely for the transmission. Altough the engine recognizes the car is going at these speeds, the transm. keeps the highest gear (5th for 4 cyl engines, 6th for the V6 engine) at low revs, ergo, producing the rumbling vibration you hate the most. Mine has 40,000mi and never took it to a dealership, it is not as bad as it was at the begining. The Cruise Control situation, i have the same problem and is not gonna change, due to the same ECUs situation, both of them conflicting wether it is fast or slow, rich or lean, up or downshift, until they get a program solution. All i do is: engage cruise ctrl while on straightways and disengage when coming to an uphill. Other than that, I think is the best investment I've ever made. Just ordered a set of wheels for it this week. Hope this will help.

Had the same problem on a 2007 Corolla. The check engine light was on, had hard shifts, and a DTC code of P2716. The computer had to be updated. I would take it in and ask them about this TSB.
