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.

Your overdrive should kick in at about 45mph, pretty much at or about 2000rpm. To see if it engaged, lightly touch the brake pedal and it will disengage.It should also disengage when you mash the pedal down to go into passing gear, and re-engage when conditions "normalize" again. You can tell that it has engaged because the tach will drop a few hundred rpms. If it's not doing this, a simple trans oil change (with filter) may correct the problem. OD is activated by a shift solenoid on the valve body that may be a bit gummed up.
95's show a shift control module on some diagrams I've seen, but not on others. I read this as a possible "half-year change" So you may or not have one. If you do, I'd check that as well!

Looks like the fautl code refers to the stuck solenoid on the shift control valve which is in the valve body.
It is a job that requires lots of precision and probably if you take the valve body out you'll need a plan to reassemble it...I would suggest getting it to a specialist.

That sounds like a left front wheel bearing gone bad My friend.. turning right transfers weight to the left side and it probably has a roar similar to a turbo fan jet.. Try it and lemmie know.. thank you

it could be a motor mount check the condition of it or it can be that something with the suspension might need attention . . those things can cause vibration at certain speeds
