It listed dual. I tried to go see the other side, but the trees blocked the view of the driver side.
nope.

Nope. 18 tacomas had TSS installed and nothing changed for them.
Not sure if it matters but they had a newer transmission at the get go though.
They can just use current parts from the GX 460 to fulfill that piece for BSM and RCTA.
If they want to do Safety Sense as claimed on all '20 GX 460s they will need make the Driver Support package standard on all trims and pull in the pre-collision sensor from a LC/LX for the pedestrian detection piece.

The transmission is practically identical to the 6 speed. Literally they share the same internals and housing. The only difference in the valve system. The 6 th gear is already in the gear train. The 5 speed simply doesn't have the valves setup to choose the correct combination of clutches internally. Toyota should at least upgrade the transmission and regear ther diffs.

Love the army green but push button start is terrible. Why Toyota why?
I hate push button start, just hate it.

I don't know the answer to this. Out of all of the internal parts there it's one slight difference on one coast mechanism. I've compared the two parts sets side by side. I don't know if that part is necessary for 6th gear or for some other reason like noise or vibration reduction
It's looks to me like the engineering was for a 6 speed all along. The 6th gear was simply left out when the 5 speed was introduced. That's why all the 6 speed models share all the same gear ratios but with an additional over drive. And Toyota's literature on the transmission also confirms that the 6 speed shares the same gear train.
There's no doubt that a 6 speed full assembly would bolt in to the place of the 5 speed. They share the same housing and input and output shafts. I also am confident the 6 speed valve body would bolt on to the 5 speed gear box. But I don't know for sure how it would function.
It's cheaper to buy a full 6 speed transmission. That's what is probably do for a swap. Just bolt in. But then there's an open question of electronic compatibility. I simply don't know if the ECU would control the 6 speed. Or if it could be done.
The final thought is the axle gearing. With bigger tires you can barely use 5th gear. 6th would be totally unusable. So it would need to be matched with lower did gears. I think 4.56 diffs would be a great match for the 6 speed.
Im disappointed toyota hasn't given us the 6 speed. The cost is nearly zero to do. Since the transmissions are practically identical for manufacturing purposes. Why not do it? The only other change would be diff gearing. And toyota already makes 4.56 gears for the 8.2 rear end. This shouldn't take much effort at all. Or cost much.

Agreed. Especially here in MN, its fantastic not to have to take my gloves off to get in and start my truck when its -20.

Push button start rules. Just like the power rear window.

If you can get this to work, you will have made history, doing something Toyota hasn't done that we wanted. I can guarantee you that I will be the first to follow suit with the conversion. Please, make this happen for science, for mankind!

I don't have any intention of trying this anytime soon. I looked into it to see if I could make the 5AT use 6th gear with just electronics. I don't think it can work to make the right set of clutch packs engage with the valve setup in the 5AT. The a750 has 7 solenoids and the a760 has 9. You can look through the differences in shift function here: A750E A761E ZIP IN It shows an extra clutch in the a760, meaning that I don't think the 5AT could probably shift to 6th gear. Essentially Toyota removed one gear option from the gear set to make it a 5 speed. So I kinda gave up at that point. It would make more sense to sell my 4Runner and buy a GX or LC200. It's really the electronics that I'm not willing to spend the time sorting out. I can see it easily burning through dozens or hundreds of hours to build a intermediate control unit and write some basic software to communicate both ways between transmission and ECU. The mechanical part would be easy enough. - but who knows? Maybe it just plugs in and works? (I really doubt it, but stranger things happen).
If you're interested: (Note that the difference in internal parts is part 559 - coast drum and associated clutch 4 - that is not present in the 5AT. What you'll notice though is that the C4 clutch is actually the same physical parts as the forward clutch on the 5 speed. Same number of discs total and same parts. Just identified as two clutch packs instead of one. There's just a couple physical parts that you need to change to make a 5AT into a 6AT internally. After looking closely again I believe that is likely necessary for the 6th gear to have the extra parts. As I look closely I'm now pretty confident a valve body swap would not get you there. You'd need to buy a complete 6AT or buy the missing parts and install them in the 5AT.

I was able to see through the trees from behind today. It's just a side exit on the passenger side. Not a dual exhaust. Just another typo on that card.

I wish I knew more about transmissions to chime in. Theoretically, if one were to acquire the correct 6AT tranny & gearing, I wonder what would happen...
Maybe hate was too strong of a word, but after fumbling with the stupid thing for ten minutes trying to get it to start, while at a rest area, I taken a dislike to them. The battery was dead, did the whole use the fob to push the start button to start thing as the manual said, and the thing took forever to finally read it and start.
