Automatic transmission issues. Should I re-gear?

I've had this Tacoma for over a year (just hit 8k miles - stock height/wheels/tires) and I constantly run into issues with my automatic transmission. When going up steep hills, slowing down, speeding up, or merging, my transmission will usually act up or hesitate. Sometimes it will rev up to like 6,000 rpms before automatically switching gears. Sometimes the transmission will be in too high of a gear when slowing down which will briefly cause the truck to lock up or stutter for a second. I've had the dealership look at it and they said it is somewhat normal but a little unusual (this was 8 months ago). Sometimes I drive in S mode or turn on ECT mode if necessary.

Heres an example when going up a hill and merging: https://www.youtube.com/watch?v=fcNeMN_QObg&feature=youtu.be

I've heard re-gearing will clear up some issues and it can possibly improve the handing, power, and mpg. Any ideas?

 

I thinks it has something to do on how you drive. On how you press/depress the gas pedal in quick succession.The pedal is electronic and there’s some delay . From what I hear it’s like you press then depress the delay confusing the trans. You have to re learn how to drive to be able to overcome that issue . This is just my opinion.

 

I occasionally do that because it feels like it is revving way too high (around 5k rpms before switching automatically). Im fine with other vehicles but the tacoma is kinda weird about it. I had a honda ridgeline before I bought the tacoma lol

 

If you press the pedal too fast , it will do that. (It will hold to that gear longer or drop a gear or two) go easy. There’s no fix for that. Except maybe the next bronco pick up or the gladiator. Wait till you put in larger tires and armor, it will amplify those things and by the looks of it will drive you nuts.

 

New broncos are pretty cool. About the driving thing, I guess it’s kinda a habit. I’ve had my drivers license for 2 years, so that’s when I started driving automatic transmissions. I raced dirt bikes from age 11 to 17 so I’m still used to standard transmissions and the clutch.
