How to check automatic gearbox condition?
At the moment of steady speed, the tachometer should show no more than 2,000 rpm for a 6-speed gearbox; and no more than 3,000 – for a 4-speed gearbox. If the readings are higher and the engine roars, the box is faulty. Check the used car operation on automatic downshifts. Accelerate and coast the vehicle. Switching should be flawless, with no jolts or kicks.
