Ls 400 Aut. Transmission Knock


Recommended Posts

Dear All,

I am experiencing a knock or thump in the Aut. Trans. during deceleration from 2nd to 1st gear at about 25 to 30 Km/h. (it feels like a kick in the butt) This does not happen all the times. Usually happens when engine already hot. All other up and down changes are perfect.

Has anyone experienced something like this befor ?

Any comments would be appreciated to:

Do you have the gearbox set to PWR mode?

I have experienced this with ather auto boxes and really think there is nothing really to worry about

suggestion would be to check your tranny fluid too... just a possibility
