    You do realize it is a documented problem known to Toyota. I actually have it written on my last in service record that the Tacoma transmissions can search/slip when going up or down a hill when the correct level transmission fluid level shifts. I was also told by the service manager that the transmission is constantly learning or searching for shift points to match the engine RPM's to improve gas mileage which is not working as intended. So much for a myth!

    I have an auto, but if I have an MT, I'd probably downshift on the highway at times, too. Maybe a 4 speed auto or a three on the tree would be less busy, but there would be a whole lot of sacrifice. That's how we got to 2020 and pickups that get an honest 15mpg+ which is a far cry from not too long ago.

    5K miles and the ‘20 shifts identical to a ‘17 with all the latest TSBs.

    My wife has a 2015 4.0 with and automatic transmission. My truck is a 2108 3.5 with an automatic transmission with the "magic fix" transmission TSB applied about 10,000 miles ago. My 2018 still shifts like a POS in Drive. If I use ECT and S5, my 2018 shifts almost as good as my wife's 2015 in Drive...and the 2018 has much better high RPM performance.

    I've been driving manual vehicles almost exclusively for 30 years and I NEVER have to downshift at highway speeds, unless I'm on a pretty steep incline...never on a slight incline. These issues are definitely not normal shifting behavior.

    Also, I've been reading a lot about the 3.91 gears in this truck and that fact that they may have more to do with these shifting problems than a lot of people think. A LOT of 3rd gen owners have re-geared to 4.88 or 5.29 gears and have seen huge improvements in the auto transmission's shifting behavior. Maybe the core problems has been the too low gear ratio all along and maybe explains why MT trucks are arguably better to drive, as they have a higher gear ratio than the auto.

    Somewhere in this thread, I thought I saw something about incline, but point well-taken about the amount of grade.

    The QC issue you describe has been around since the first 3rd gens rolled off the line in 2015. It’s one of the reasons I sold this 2017. Cruise control was unacceptable.

    It’s a shame to see frustrated 2020 owners.

    Well, 6th gear is pretty worthless, but even locking it out and enabling ECT wasn’t enough. At least it wasn’t on my 2017.

    Doesn’t really matter. The 2020 Tacoma truck I want doesn’t exist in Texas. Makes it hard to do test drives and work a deal.

    The 2020 'tune' seems to be a noticeable improvement.
    The 2020 doesn't lug in city driving like my old 2017 occasionally did.
    Also when using cruise control the 2020 does not display the constant downshift and distinct throttle increases when going up inclines that the 2017 did. The 2017 seemed to always be trying to get me to 1100-1500 RPMS as quick as possible, but the 2020 seems to be OK at higher RPMs, and when it does downshift, I don't notice a drastic throttle increase. The 2020 is definitely holding the gears longer, and seems to be OK at the higher RPMs for a longer period before upshifting to 6th.

    The 2020 improvements are pretty apparent. Lots of comments in this thread are from people who haven't owned both.

    Done a couple of 500 mile road trips to Bend and back and haven't noticed anything I'd complain about.

    The only thing that bothers me on my ‘20 is how long it takes for the transmission to shift back into 5th or 6th AFTER cresting a long, steep hill on the interstate - up to 5 seconds or so. Truck is going downhill and the thing stays in a lower gear way too long. My 2nd Gen never did this and I find myself turning off the cruise in hilly terrain. I’m able to keep the downshifting to a minimum and the truck is a lot smoother without the cruise on.
