Gearbox will cost you a total of 40K if you replace with a kabli including everything 40K..
Don't remove the catalytic converter
Just get it cleaned
And Toyota company should do cleaning of passo too as they do of corolla..
If it's jerking only when gear shifts then it's the issue of the gear..
And is it cvt or just automatic?

Check your spark plugs
Looks like they are misfiring, try fitting another set of spark plugs. Your car must be giving jerks at low throttle, at high throttle there won't be any jerks.
Am i right?

automatic . i live in multan here they dont have chemicals to wash it so they remove it

[pwuser148440473555]

Removing catalytic converter isn't a good idea
It causes pollution + decrease in fuel economy + decrease in low end torque + increase of noise..
When the catalytic converter is clogged the car does alot of missing and even before putting into D car engine switches of by itself
So try changing plugs maybe plugs are misfiring and if it remains then change the gear with a kabli one

[awanzaini7]

yes your are right it starts jerking when the car is moving very slow
or when i put the car on reverse gear then it jerks alot

[adnanls460]

check the solenoid switch of the Gear

[pwuser148440473555]

Then it might be due to catalytic converter
Ask any local mechanic to service it but don't do the blunder of removing it..

Brother. It's not gear issue at all . Nothing is wrong with gear . It's about engine only . Your engine Colling system is not working properly. I know you don't believe me . I advise you a experiment. Rat ko gari ko start karu after 12 and take a ride of 10 kilometres.(rat ko is lia k temperature low hota atmosphere ka) You will not fell any jerk . Apnay paisay fazool chezu pa waste krny sa pahly ya experience kar lo. Agar experiment ma gari na jerking ni ki . Then put a good coolent in radiator, and check your fan switch only.

I advise you the above assuming their is no sound in gear or low sound

[farrukh9999]

Start car from zero temperature

Ok don't mind I share my personal experience only . It may not work same

[farrukh9999]

If u don't mind . It's your car I am no one . But just try direct fan after 2 hrs of rest to car . Try it .

[awanzaini7]

ok i will but tell me the role of throttle body in my prblm ?

[farrukh9999]

Throttle can damage pick of the car . Jerking is little bit related ni ha . Throttle karab hu to if you poush paddle hard gari phly bhthy gi then suddenly start pick the race

[farrukh9999]

Your engine is perfect. Gear is perfect. Only colling system is faulty . Make fan direct
