Honda expands U.S. auto recall for transmission flaw

The engines run hot, partly for emissions, and because of this, even regular dino oil would barely stand up to normal maintenece intervals, if at all before it would sludge up. (The whole engines wouldn't run hot, its just certain parts along the oil passage would have "hot spots" creating stress points for the oil) Synthetic oil use reduced the chance of sludge a lot in these engines, but, the average person doesn't use synthetic in their Siennas and Camrys. If one of these engines are in your car, I suggest changing to oil every ~3,000 miles if you are using dino, and 5,000 if using synthetic, these intervals will greatly reduce the chance of sludge. While most modern engines and dino oils can go beyond the "3,000" miles thing, in this particular toyota engine, going beyond ~3,000 miles is risking it.
So, even if a "user" were to follow the regular maintence oil change schedule of 7,500 miles, is it still there problem or error because they did not follow regular maintenence? Even at the severe schedule mark of 5,000 miles, thats pushing it on dino oil for this engine.

man, you can trace the lineage of this problem and see it coming from a mile away. The tranny they use in the recalled models were evolutions of the previous gen CL/TL 5 speed autos which were known to have problems. Honda just spit polished an old, problematic design and then put it in the current cars.
Their I4 ATs are still pretty solid but Honda is obviously having growing pains building high power/high torque auto trannies. I wonder how much of this situation is caused by size constraints of trying to build a strong AT with lots of gears that will still fit in a smaller, FWD frame.

Yeah, it's almost got to be the transaxle design. Seems like all high-powered FWD Honda have auto tranny problems.
EDIT: This coming from a former 2001 Honda Prelude owner.

Serves those people right for not getting the V6-6spd. 😉

The situation is created by insufficient lubrication of the transmission's secondary shaft second gear that can occur under certain driving conditions. Prolonged operation under these conditions can lead to heat build-up and under certain circumstances may eventually result in chipped or broken gear teeth or breakage of the gear. In the event of a chipped or broken tooth, the owner will likely experience abnormal noise from the transmission and seek repairs. In rare instances, this condition may lead to gear breakage and possible locking of the vehicle's transmission, creating a potential safety hazard.
Holy Fvck! This is exactly what happened to me! Not the last sentences, but the 2nd gear was really problematic to me. It shifts the hardest and to think of that, on my rebuilt transmission I still notice a bit of jiggling when I change gear to 2nd. Damn, this can't be good....should I get a transmission cooler?
