    I have a 2005 V8 4Runner with 73k miles. I am experiencing very hard shifting when traveling 60 MPH and above. It is very evident when descending and ascending the rolling hills outside of town. It occurs on both down shifting and up shifting. The shifts are very hard and "clunky". A passenger was with me the other day and was startled by how hard the shifts were so, I know it is just not me. I took it to a transmission shop. They drove it around the corner a few times and did not experience any clunking. I told them it happens on the highway only. They said if something was wrong it would be throwing off a code on their machine and when they hooked it up there were no codes. I love this truck but, I need to get this fixed or I will have to sell it. It is just too annoying and I drive out of town regularly and cannot afford to be stranded.
    Any suggestions on the cause of this problem will be greatly appreciated.

    Thank you!

    This and that
    Find a better shop. It's just not true than transmissions will throw a code when shifting hard. I suggest changing the fluid as a starting place assuming it has the original fluid.

    yeah your transmission isn't going to generate a DTC, id change the fluid as chris said, thats the most logical place to start

    Update on my transmission problem. While the symptoms pointed to a transmission problem, it turned out to be a defective ignition coil. The defective coil resulted in misfiring. The misfiring manifested as really clunky shifts. Gotta give kudos to the dealership on this one. They figured it out. After the fix my 4Runner is running great.
