How many miles on the engine? How often (milage) have you change the transmission fluid?

When you actuate the OD button does the "OD Off" message go on and off on the dash display?

Are any indicator lamps flashing?

It should because normally with O/D off, the car won't shift into 4th gear.

The SL controls the torque converter lockup. Basically when the TC locks it behaves like a manual transmission with a clutch and power is no longer lost moving through the torque converter. You will only notice the RPMs drop about one or two hundred but shouldd definately feel a differnce in the gas pedal when you try to accelerate with it locked up. The vehicle speed will increase directly in proportion to the engine speed, instead of a small increase in rpms then an increse in vehicle speed.

You may not notice all this happening until you look for it though, most people don't
