Gearbox problem

Could be low transmission fluid,or bad shift cylinoid,or even a bad transmission mount.

Could u plz tell me a little bit clear sir

First thing would be check your transmission fluid,if fluid is good and not low,and car shifts ok when you take off,then cylinoids are ok,next would be check the mounts on the transmission one may be busted giving you that shake.

What u mean by bad shift cylinoid? And bad transmition mount?

My car shif normally from 1 to 2 then to 3 but when i break my car i mean when my car becam slow so the gears shif back from 3 to 2 then one at this time it shake ? Genrally its normal

If it is shifting normal when you take off,and only does this when you let off the gas,it wont be a bad cylinoid,check the fluid,then check and make sure there is nothing binding car when you let off the gas,such as bad cv axel,s or rear end issue or even brakes,if the car down shifts like this there is something holding it back.

Yes it did when i let the gass off. It shake the car for a second then change the gear from 3-2-1 ? But i cant get ur answer clearly sorry for taking ur time
