Is my 2018 shifting normally?

I've never had an automatic anything that acts like my 2018 Limited 5.7 liter. But, then, I've never had one later than a 2013.

I can be rolling along at 45 mph, the tach at 1200 (or so) rpm, and let off the throttle. It doesn't freewheel at all. It just stays at 1200 rpm and starts slowing. It acts like a standard transmission. Other automatics I've owned will start coasting, or freewheeling, and the engine will drop to near idle. The truck acts sort of like it's in tow/haul mode when it's not.

Bear in mind that almost all of the 3000 miles I've driven this truck so far have been in tow/haul mode pulling a 6000-pound trailer. Could it just be remembering my driving style and adapting accordingly?

 

My 21 does the same thing. But wait! it gets even better! Start decending a hill and it downshifts to add engine braking.

 

Bingo! And that's expected behavior in tow/haul, but I've never had one act this way just driving. If it's normal, though, that's OK.

Thanks for the answer.

 

Both of the Tundras I've owned have been that way, and personally I don't think there's anything wrong with that. Only ever owned one other truck that had an automatic transmission and I think it was the same way.

 

My 2003 Tundra didn't do that, but then, it was a 2003 No, I have no problem with it if it's normal. I just wanted to see if it was normal.

Thanks for the answer and putting my mind at ease.

 

I've had multiple tunes on my 2008, and regardless I always have to do S6 to make the truck behave like a normal automatic. Otherwise it won't upshift, holds gears when it shouldn't, list goes on of weird shit it does.

 

my '21 does this, and I wish it didn't.

 

Yeah, it doesn’t coast like other trucks. I always thought it was due to the 4.30 rear end.

If you just barely keep your foot on the gas it seems to coast better. Mine doesn’t downshift any more when coasting, and I think it’s at least in part due to the fact that I keep my foot on the gas just a little when going down a long grade instead of purely coasting. Keeps the instant MPG bar lit up all the way, and the truck doesn’t decelerate as quickly. Seems the transmission has learned this as part of how I drive.

 

I guess you could say it is a standard transmission, in that there is a lockup clutch that will give you direct drive from engine. It helps with fuel economy and heat by not having the torque converter spinning and slipping loosing efficiency at highway speed. I really like this Toyota design, think they have done a great job with their transmission. I don't know if all trucks out now have this feature but know several do.

 

Yes our trans does weird stuff. It has to make sense to some engineer

 

or some government bureaucrat/lawmaker.

 

At this point I don’t think anything of it because my 4.0 2012 Tacoma and my 4.0 2017 4Runner did the exact same thing. It “seemed” odd for the first few months with my Tacoma.

 

MY 06 and 18 do it.

 

If you're someone who notices what the Transmission is doing and you're not happy with it, then take control of it. Toyota made it really simple with their Sequential Shifter. It's a touch more 'involved' than just putting it in "D" and letting the truck do the "thinking" but it's worth the effort.
