Auto Tranny Fluid

    TRD S/C, TS PNP AEM FIC, TS 625cc injectors, TS 2.2 pulley, Hayden tranny cooler, AEM wideband, TRD boost gauge.
    So I bought the 01 with Mobile 1 syn in the engine, and he said it had redline ATF in the tranny.

    My concern is that I've read more than once that with Toyota Auto Trannies, that Toyota fluids must be used as they have the right friction modification and what not.

    I've noticed with this Tacoma, if not coming to a slow stop the auto tranny seems to stay engaged until stopped and then "stutters" to idle like it was engaged till the full stop and gets some kind of clutch slippage feel.

    Is this normal with the truck, could it be the fluid, could it be too late and a rebuild is coming up?

    Thanks,
    B.

    I think the '01-'04 trannys needed the T-IV fluid from Toyota. I'll see if I can find some info on that somewhere.

    update: here's what I found on the customtacos.com site

    2rz - Toyota Genuine ATF D-II or DEXRON III(DEXRON II)
    3rz and 5vz - Toyota Genuine ATF Type T-IV

    Hmmmm, I thought only the '01+ V6 and 4 banger needed the T-IV fluid only.

    My Dad is running this stuff in his 2004 Tacoma Prerunner (5VZ) and doesn't have any problems. I'll be running it here shortly in my 99 4Runner.

    Yeah, I'm running the Amsoil as well. Didn't do the full flush, but rather the drain and refill.

    Has anyone found that you cannot check the trans fluid in your second generation tacoma.. In order to have it checked/ changed you have to go to the dealer. The trans has no dipstick. You take it to the dealer, the dealer pumps the fluid in throught the bottom of the trans and the only way to tell if it is full or not is to hook Toyotas computer to it and read the trans temp. I can honestly say that this was not one of Toyotas better ideas.. The new fords are the same way, I know the Ford escape is this way for a fact. WHY!?!?!?!

    I know that this is true on my 07 5 speed manual transmission. I asked the dealer about it when I bought it. He told me it is a sealed transmission, and that it is zero maintenance aside from clutch replacement once during it's lifetime. He said that Toyota is that sure of the build of the 5 speed manual tranny.

    Personally, I think I would like to be sure myself. Just in case.

    I think that is true of the automatics not the manual transmissions. I'm going to say the dealer fed you a line of bs because I was able to drain and fill the 6speed when I had my '05 Tacoma. I used 75-90 Amsoil gear oil and noticed a huge difference in the way she shifted. If you can get some pics of the trans (pm them to me) and I'll try to located the fill and drain plugs for you.
