    Default corolla saloon a/t 2003 jerk and low pickup

    Hello everyone,

    I am experiencing a similar situation as post in older thread on pw link below
    https://www.pakwheels.com/forums/eng...2003-t-problem

    i went to the mechanic a week he changed the transmission oil (corolla t4) , drained the old oild by opening chamber, service the transmission, cleaned the trans filter properly, though he didn't perform a full flush at that time, this whole procedure didn't make any difference, jerks are very obvious specially during traffic hours..

    As xulfi bhai mentioned on that thread to get the filter changed I asked my mechanic to do so, but he is keep insisting that there is nothing wrong with the filter and ask me to come again tomorrow for further checks,

    wondering if anyone could help with suggest possible problem and solution in this regards..
    also if i go with installing new trans filter, where can I get it from, due to the office it won't be possible for me to go to plaza if any one could suggest a place near by gulshan would be highly appreciated.

    Did you change the fuel filter as well?

    No, I was asking about the fuel filter which is inside fuel tank. Just make sure you have been changing it regularly for correct fuel supply to engine.

    It looks like this:

    This is not a fuel filter,it is called fuel sub tank attached with fuel pump.

    If you cut it you can see the filter element in it.

    filter is quite costly toyota guys charge 8500 for trans filter
    anyhow , did yoy check the transmission oil level later on at cold transmission and hot transmission?if no than do it
    5 litre is too much ,owner manual says upto 3 litres but 3.5 to 4 shows good reading on dipstick
    are you feeling jerks at every gear change or just shifting from 1st to 2nd? a minor jerk from 1st to 2nd is ok but noticeable jerks are alarming .do you feel a jerk in car once shifting from p to r or d to n?
    note engine rpm once gear shifts and must note engine rpm at 80 to 100 speed.ideally it should change gears below 2500 rpm(OD ON)if you feel rpm rising above 3000 and stucking in it means gears ae slipping
    No one cares for Toyota more then Toyota

    I have faced the similar issue in past and few simple steps will resolve the problem. Check the Voltage at battery terminal with different load to see if it is above 13 Volts or not. Alt-S fuse in corolla 2002 to 2008 sits dummy and has no connection made by the Indus Motors. This is a reference wire for Voltage Regulator on alternator and low voltage supply to fuel pump normally creates this problem. This simple test will point if the issue is with improper Voltage or not.
    Second probable cause will be faulty or dying one of the ignition coils.

    nope nothing as such just when gears put into D, it takes a jerk, one could literally feel that. checked few mechanics and all suggested to put a kabli box(cost around 30K)

    Well, I was facing exactly similar issue. Thanks to GOD I have a very good and educated mechanic in contact, my problem got resolved.

    First of all I went to CNG mechanic, I told him jerks are very minor on potrol but great in CNG. After inspection he said one of the spark plug coil must have been damaged, go to some mech with computer to diagnose which one is faulty. This was the point when I decide to go to my main mechanic who never ever disappointed me ALHUMDULILLAH.

    After inspecting and performing some tests my mech said coils are working perfectly fine and I see no problem in your car, it seems to work perfectly fine. After hearing that, I asked him to come with me for a test drive on a long clean road, he instantly agreed.

    During drive, in start he did not feel minor jerks but after a while he started observing, and became serious. He stopped the car to a near by Auto Electrician shop and told him "Majeeb Bhai, I feel car is lacking current some times, I've already checked, coils are fine.". Majeeb Bhai, believed what a mech said and went to fuse box in the car's bonut. Made all the fuses and relays seat firm in their position and said check now. We took a test drive again and problem seemed to solve.

    Then Majeed bhai told us that 2 fuses are getting heat up and melting. Change the whole fuse box with some Kabli. Your car is working fine for now but may get problems later. I asked him what would be the price of a Kabli one, he said 4-5K. I didn't like the price and asked him if any work-around(Jugaarh) is possible? he said yes we can by pass the 2 fuses who are heating up and melting. I agreed to do this and Now MASHALLAH, I'm satisfied with the car performance.

    Brother never bypass anything. A good mechanic would investigate that why fueses are heating up. Now that he has bypassed fueses there is great risk of short circuiting and even fire.

    Undo the bypass, hook the fueses again and check the source which is causing heatup to save yourself and your car from any huge damage.

    The maximum life of a "Jugarh" should be the time you face a problem en-route, to mechanic's place and not more than that.

    Fuses were not blowing, instead were start/stop working, getting heat up and melting due to loose connection. You know loose connection causes spark.
    Seats of the fuses are too old and have wear out in 10 years. Nothing serious dude, simple problem, simple solution.

    I m still having the problem unfortunatley none of the mechanic able to sort this issue. I didnt go with the gear box as of yet.. Often car becomes heavy and heaviness can be felt on making turns.. And in slow traffic.. Rpm goes up and down in slow traffic between 1000-1600.. In particular when put brakes rpm goes up a but upto 1500 and then decreases to 1000.. The behavior is worse when ac and lights are on..

    Do you live near Gulistan-e-Jauhar, Karachi. I can provide you reference to my Mechanic. There is nothing wrong in atleast getting advice from him.

    After Karachi University, then comes Shaikh Zaid Center, keep going straight till you find this road tuning left. Just before this left turn there is "Rufi Shopping Mall". Take your car in its parking area. Mechanic shop is in neighbor of this shopping center. Mechanic name is "Ashfaq Bhai".

    There are 90% chances INSHALLAH he will be able to sort your problem out. Don't forget to reply here after you pay him a visit.
