Q: what are the B1 B2 ect. services? 95,000 miles on the car.
on 2009 Acura TL

I have a 1999 acura tl 3.2 with 200,000 miles. When I begin driving the tranny acts fine but ince i start to cruise the gears start jumping and d4 starts to flash. Ttied changing the fluid but no change. Please help.

I have a 1999 Acura TL 3.2L and none of the door locks activate by the switches inside. As the previous owner lost the remote I cannot see whether the actuators work yet there is voltage being provided to the switch harness. Thanks

So I gave my sister the car for the day and she drove on the highway for about 7 hours... Turns out she was in triptonic mode accidentally and noticed the car driving oddly but didn't think anything of it... She said it "sounded like an airplane" Thankfully the car changes gears automatically even while in triptonic mode, although it does so only when absolutely needed... My question is what kind of damage could this of done? Should I take it to a mechanic, oil change, transmission fluids?
