    I have a 2001 Tacoma with a 2.4L automatic transmission (A43D) that was rebuilt at 211K and now has just over 300k on it. Changed the fluid recently and it does not shift correctly, may require high revs to finally shift, so I now shift manually from 1 through 3. Can anyone advise what I need to be looking at or checking out to finally solve so I can just put it in drive and let it shift on it's own? Thank you.

    I thought these only came with manual transmissions and the 2.7 had the option of both?

    Your shift points are mechanically controlled by a TV cable or Kickdown cable. Its a cable that goes from your throttle plate to your transmission. My truck wouldn't shift out of first gear the other day. The cable was stuck wide open. Check to see if the cable moves freely.

    OP it could be a number things, shift solenoid could be out, or the pressure solenoid could be out. I had this same problem with the transmission in my Monte Carlo and it was both of them gone out. Your torque converter may be locking up and not releasing at the right time also.

    no, they always had autos but the factory puts out like 40% auto and 60% manuals so you see a lot more manuals then autos
