    Howdy all. I'm just questioning if the transmission could play a part in poor fuel economy? My auto tranny is almost 100,000kms overdue for a service! :p And i think i'm finally going to get around to it. Do you think a service on the auto could also bring back some of the torque that's missing from my VS? I've driven both my old man's VT and my VS and with power to weight, mine should be shitting all over the VT. Butttt it's not quite so, acceleration seems to feel very lumpy and the accelerator pedal isn't as responsive as the VT. The other theory i had was maybe it was injectors, but still haven't got around to checking them out yet either! Any input would be great.

    Thanks all,
    Boojakz.

    Ive always thought that as well. My auto feels very lazy in it response, shifts are quite poor sometimes they are extremely firm other times very lazy. Also kickdown response can be poor as well.....?? Ive serviced mine however, but hasnt brought it back to life at all. Its just shagged!

    check how slack your accelerator cable is aswell if you feel the accelerator isnt as touchy. Adjust it accordingly.

    What is your economy like? What makes you think the injectors need a clean?

    14.5L/100kms. Was at 15.5L/100kms, ran a dose of injector cleaner through the system and instant improvement on the next tank. Also throttle response was marginally improved!

    Well the 4L60e auto trans is pretty lazy, compared to other cars.

    Well. Took the car in for a tranny service today. WOWEE! what a difference 1hr can make! She pulls really hard now, and chirps through the gears. Don't know whether this will help economy, but the torque i've regained is amazing! Lol well that's what you get for leaving your tranny 100,000kms overdue for a service! Will take the car back into mechanics on Friday to replace fuel filter as that has never been replaced in its life! (219,000kms old!). Will keep you all updated as to next litres per 100kms as of next tank and so on for the next couple of weeks.

    Cheers,
    Boojakz.

    A fuel filter is $10 if you do it yourself, the mechanic will probably charge you $25. Its pretty easy changing the fuel filter!

    Yeahhh i know, actually paying $30, but i'd rather pay out the extra $20 and let them get their hands dirty. Also i got the reliability that if something ****s up, i can put the blame on them!

    Cheers,

    Had the fuel filter replaced today. They showed me the fuel that was getting through the filter. Once passed the fuel filter, the fluid was BLACK! and i mean practically MUD!!! And to think my poor baby was feeding on that for the past, who knows how long! Noticed an instant difference in power. Lol i suppose that's what you get though for not replacing the fuel filter for 219,000kms!!! Will update you guys to let you know how fuel economy goes. Still may get injectors done, as i think they're still not the best at the moment. Next post in this thread will include Litres/100kms before and after results for fuel filter and if i do get injectors done, will post before and after results for injector rebuild.

    Cheers all,
    Boojakz.

    Bet ya the injectors are dirty aswell, run optimax and some fuel injector cleaner (or get it serviced), drive on the highway and it should be clean.

    Also changing the fuel filter is a piece of cake, you have to make sure to take note of the arrow (showing direction of flow).

    Been running optimax since 100,000kms approx and have run 2 bottles of injector cleaner through in the previous 10 tanks or so. Noticed an improvement there too. Now i'm just wanting to get them professionally rebuilt.

    Cheers,
    Boojakz.
