I had to really hard brake today over a very very short distance…the tires locked and the car slid for about 5 feet. Car is 2000 corolla, 4-spd auto.
As soon as I came to a full stop, I notice the engine was still “spinning” like it was in second gear…because the RPM was around 1000rpm (idle is 650). As soon as I started moving, there was a slight clunk noise (sounded like it came from CV half axle/transmission).
Although rare, This also happened a couple of times before when hard braking. It downshifts to 2…idles around 1000rpm for a couple of seconds…and then there is a “slight” clunk noise.
Other than this, the transmission/engine has been very smooth and the car has no problems.
