    Default Toyota Corolla Fielder CVT transmission problems, please help.

    Salaams,

    I am from Malawi (Africa). I have a 2007 Fielder 1.8s. Recently I traveled abroad with the car (almost 1800km) on my way back about 200Km from my place, suddenly the car lost power and started slipping. I continued driving slowly as it could not go beyond 2000 revs, if it went above it was just the engine roaring and the car was still at the same speed. Finally it could not go up one of the hills and I had no choice but to tow it home.

    I then removed the gearbox and after checking I noted that the Forward Clutches and Steel Plates were severely damaged, and also the Forward Piston Seal was also damaged.

    I ordered those items from New Zealand as that was the only supplier I could find online. I replaced those parts and the filter too and filled it with original Toyota CVT-TC Fluid.

    Now the problem is there is a delay in engaging from P to R and D specially when its hot. And when testing the vehicle at a certain point the vehicle is juddering/slipping and can not take off. I have to put it back in P, switch it off and then start again then it moves. But also whilst moving it judders at times. Also I noted once when I stopped on junction while the vehicle was in D and brake fully pressed it sounded like the gear has engaged again. As i was going up a small hill at about 60km/h I also saw the rev meter keep going up and down as though its changing gears, until I accelerated more and it went normal.

    I was advised by one of the member of Pakwheels to clean the valve body which I did and also opened the transmission again and changed some O-ring seals but the problem is still there.

    Please help and advise....... I will appreciate

    Wellcome to PW. Nice to see you here brother.
    Can you get the car tested with a proper scanner? See if the transmission throws up some error codes.

    Got the car tested on a Toyota Global Techstream scanner and didn't get any codes at all.

    After driving around for a few days and adding about 500ml more of CVT fluid, it has greatly improved. No more juddering and engages in Reverse immediately. But unfortunately in D it still delays and it is harsh engagement. Specially when the engine is hot.

    Any suggestions on the harsh and delayed engagement?
