2016 gear ratios. AT awesome, MT now with double overdrive.

The tech specs are out and the gear ratios sure are something.


Don't get too excited (or butt hurt) about the double overdrive in new manual transmission. The overall gear spacing of old MT found in the 2005-2015 is basically identical to the 2016+. With a rear end of 4.3 and those gear ratios you end up with final drive ratios of

Code:

2016 6MT    1st  2nd  3rd  4th  5th  6th
Gear ratio  3.98 2.02 1.32 1.00 0.85 0.71
Final drive 17.1 8.69 5.68 4.30 3.66 3.05

Compared to the 2005-15 one with a 3.73 rear end

Code:

2005 6MT    1st   2nd   3rd  4th   5th  6th
Gear ratio  4.171 2.19 1.488 1.193 1.00 0.849
Final drive 15.56 8.17 5.550 4.450 3.73 3.167

So if you liked the spacing on the current 6MT, its good news for you. The short end is a tiny bit shorter and the long end is a tiny bit longer.

On the road, given stock 30.5" tires, it translates to these speeds. The left column gives the RPM and each subsequent column gives MPH in each gear. Most important is probably the last column for 6th gear. Its slightly lower than the current 6 speed manual.

Code:

2016 6MT
RPM     1st     2nd     3rd     4th     5th     6th
1000    5.30    10.4    16.0    21.1    24.8    29.7
1200    6.36    12.5    19.2    25.3    29.8    35.7
1400    7.42    14.6    22.4    29.5    34.8    41.6
1600    8.48    16.7    25.6    33.8    39.7    47.6
1800    9.54    18.8    28.8    38.0    44.7    53.5
2000    10.6    20.9    32.0    42.2    49.7    59.4
2200    11.7    23.0    35.2    46.4    54.6    65.4
2400    12.7    25.1    38.4    50.6    59.6    71.3
2600    13.8    27.2    41.6    54.9    64.5    77.3
2800    14.8    29.2    44.8    59.1    69.5    83.2
3000    15.9    31.3    48.0    63.3    74.5    89.2

Now for the AT. With the new 3.909 rear end gives these final drive ratios

Code:

2016 6AT    1st   2nd   3rd   4th   5th   6th
Gear ratio  3.600 2.090 1.490 1.000 0.690 0.580
Final drive 14.07 8.170 5.824 3.909 2.697 2.267

and the 2005-2015 for comparison with the 3.73 rear and only 5 speeds.

Code:

2005 5AT      1st      2nd      3rd      4th      5th
Gear ratio    3.520    2.042    1.400    1.000    0.716
Final drive   13.13    7.617    5.222    3.730    2.6707

essentially it is an extra gear on top. This is basically what I was expecting to see with an extra gear. The new transmission ends up translating to these projected speeds with a 30.5" tire, if anyone is still reading by this point.

Code:

RPM     1st     2nd     3rd     4th     5th     6th
1000    6.45    11.1    15.6    23.2    33.6    40.0
1200    7.74    13.3    18.7    27.9    40.4    48.0
1400    9.03    15.5    21.8    32.5    47.1    56.0
1600    10.3    17.8    24.9    37.1    53.8    64.0
1800    11.6    20.0    28.0    41.8    60.6    72.0
2000    12.9    22.2    31.2    46.4    67.3    80.0
2200    14.2    24.4    34.3    51.1    74.0    88.0
2400    15.5    26.7    37.4    55.7    80.7    96.1
2600    16.8    28.9    40.5    60.4    87.5    104.1
2800    18.1    31.1    43.6    65.0    94.2    112.1
3000    19.3    33.3    46.7    69.6    100.9   120.1

Significantly lower RPM for a given highway speed compared to the MT and the old AT. Those RPM values are so low in 6th gear I'm wondering if it will be able to use 6th very often.

Feel free to check my math. It's kinda late when i cranked all these numbers to satisfy my own curiosity. i used a conversion factor of .090737 to go from RPMs of a 30.5" tire to MPH. If someone requests it, I can run the same numbers for the 2.7L engine.

edit: I ran the 5MT. The transmission is the same as before, so it has the same gear ratios. The only difference is the rear end is now a 3.91 instead of a 4.10 (4x4 and prerunner). There was another rear end for the 5 lugger, I think. I don't know if they came with the 5 speed, whatever. It will end up similar because it had a smaller rear end and smaller tires to even it out.

Code:

5speed MT      1st     2nd     3rd     4th     5th
Gear ratio     3.95    2.06    1.44    1.00    0.81
Final drive    15.4    8.05    5.63    3.91    3.17

2400    14.1    27.0    38.7    55.7    68.8
2600    15.3    29.3    41.9    60.3    74.5
2800    16.5    31.5    45.1    65.0    80.2
3000    17.6    33.8    48.3    69.6    85.9

These gear spacings are pretty similar to the 6MT. If you go from the 5 speed to the 6 things will feel similar as far as the shift points, but the truck will actually go when you press the pedal.

double edit from the future: new documents show the new 5MT 156F, is different from the old one 155F with new ratios. The above info about the 5MT is wrong. See this thread for details. https://www.tacomaworld.com/threads/a-bunch-of-technical-info-about-2gr-fks-and-the-3rd-gen.391218/

 

Good stuff.

 

So if the MT didn't change, that's yet another thing Seat Belt Bracket Mike Sweers lied about

 

Sorry let me clarify the thread title. I might just edit it if I can.

The gear ratios in both the transmission and differential are completely different. The transmission is totally different. If you could somehow swap the new MT for the old one you would have much different performance.

The final drive ratios end up being very similar by design. They did that on purpose because apparently they want the new 6MT to have similar shift points as the last one. This is what I mean when I say no change. The shift points and wheel speeds of this new transmission, engine, and differential combination are basically the same as the existing one.

This also says nothing about how the transmission feels or shifts. I don't think anyone has actually been able to use one yet. Several reviewers mentioned not having one available to try and they'd have to try it later.

 

does this mean if you get a 5 lugger with auto tranny you can put a larger tire on without massive performance,drivability sacrafices. Hopefully you can replace the pee wee 215/75/15 tires to a size up at least without lose to performance,mpgs etc?

 

I don't think 5 luggers are available anymore... at least from what I thought I read.

 

No more 5-luggers for 2016+

 

The 4 cylinder auto should have the best improvement in driveability with 4.30 rearend and 2 more gears. Also notice they went from a 4.10 to 3.90 with the 5MT.

 

they must be crazy,there has always been a market for the basic 4x2 pickup whether commercial or private usage. I didn't realize that they discontinued this model,its a shame because a lot of people are in the market for a non 4x4 truck they can use as a daily driver,grocery getter,home depot runner or commercial usage that's economical and tough like those trucks are. Toyotas being run by a bunch of Metrosexual dopes anymore trying to sell all high end high cost Texas Pro(orange) bullshit they will lose this market to Nissan or the Domestics who still make a low cost bare bones truck.

 

what? You must be looking at the wrong table. the previous 6 speed manual had direct drive in 5th gear, and 6th gear was 0.85.

 

And all the idiot electronic toys

 

They will still have a 6-lug 4x2 truck called the pre-runner. Just no longer have the 5 lug. They did it to save money on having multiple frames. You can still be a two wheel drive Tacoma. It just isn't floored like it used to be.

 

yes,but I had hoped for maybe a better geared/auto tranny 5 lugger for myself as an economical daily driver after my GEN1 gives out(if ever). I bet the remaining inventories of 5 lugger trucks sell out quickly once people find out they have been discontinued. the little 2wd drive truck is what initially put Toyota trucks on the map as a above standard reliable economical truck back in the 1970s(gas crisis),my dad had one of them long bed 4 banger 4 speed,no AC could haul anything you put in the bed I been sold on them ever since.

 

Can anyone help explain why Toyota would choose the ratios as they did, specifically the (a) diff ratio in the V6 MT vs AT and (b) the 6th in the MT vs AT? Why go with the 4.30 in the MT vs 3.903 in the AT and 0.71 MT vs 0.58 AT for 6th?

Not criticizing, but genuinely curious. Seems like it is common that the 6th gear isn't as low in MT's as AT's in the industry...why? Wouldn't that increase mpg on the highway? Is the MT going to be more "spritely"?

 

Lol, yeah, I know. I was hoping for some educated speculation that could infer "maybe" why.

 

Great thread and charts. Thank you for the cell work.

I don't think anyone knew they were doing a 3.903 in the rear of the Auto. That's news to us

 

Thanks for the work, saves some time doing the math....

They hinted that they were lowering the gears but now we know.....

 

A lot of it has to do with the convenient combinations of planetary gear sets.

 

I usually drive at 60mph unless I'm in the carpool lane. That's like 1400rpm in the DCLB 4x4 OR

 

Bout to see some innovation among minitruckers in a few years that wanna slammed taco then
