Really hard braking, damage transmission?


#1

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.

have you checked the fluid level lately? changed the filter ever?


#3

There is no transmission filter for this car. The fluid level is good…there have been no problems with the trans/engine. The problem above is very very rare…just happened a couple of times (related to very hard braking)


#4

you got me then, but there are plenty of experts here. some one will have better ideas


#5

A guess–maybe if the motor and transmission mounts are old and loose, things shifted a bit.
could be replaced…

If your 4 speed auto is an A245E, you do have a filter. Who told you you didn’t have one? I don’t think Toyota has any filterless automatics. I’m not sure about the idle but I would check all motor and transmission mounts.

Does it have anti-lock brakes?
