Manual transmission Fan Club and BS thread (All Generations Welcome)

Tbh I can't pinpoint exactly why.

https://www.tacomaworld.com/threads/5-speed-manual-vs-6-speed-manual-strength.487880/ 2nd post (1st reply) in that thread might explain why...

Maybe someone more knowledgeable would give a better answer than I did.

 

Gear ratios. 4th gear is 1:1 in both transmissions. 5th in both are similar ratios. 6th in the V6 transmission is an additional overdrive, which I personally wish was a bigger jump. I think the thought process was the I4 wouldn’t have the power to pull the additional OD?

If you look at the AC60F below, it’s pretty clear why the autos like to hit 4th gear with any incline. Both 5th and 6th are extremely tall gears

 

Maybe not enough torque for a second OD gear?

 

^^This^^. You are right, the auto has a lower final drive in 5th than the manual does in 6th. It also explains why manuals struggle to get maximum MPG's at freeway speeds. If you look at the 2nd gen manual ratios vs 3rd gen it explains why people think the 3.5 isn't as torquey as the 4.0.

 

It is bananas how good the mileage in my truck is at 60…I did a 200 mile trip following the convoy of humvees to the field once (POV for the win!). Averaged 28.4 on that trip. I don’t have the willpower or patience to do that all the time, so I’m generally in the 19-21 range. Good enough.

 

If it’s about gear ratios, why can’t a hypothetical I4 6MT employ something like 4.56? That doesn’t seem like a technical limitation with the interface between engine and transmission.

A 4.56 6MT I4 starts to seem extra cool. The silly v6 6MT is already too tall in 1st and reverse with 4.30.

Alternatively, the RC60F might work for the 4?

I mean, my bro in law’s Freightliner has a rev limiter at 1700 rpm and 10 speed transmission. Wouldn’t more gear selection always be preferable for engines with more limitations? Seems like extra gears on a bicycle are always welcome.

4.56 will work with the 8" pumpkin for those trim levels that have it. It's becoming an increasingly popular option from what I've seen.

No kit for 4.56 for the 8.75" pumpkin that I know of.

 

Setting in the draft on those guys, I can believe it. I've always been able to beat Toyota's MPG specs, until I get on these freeways, especially in Michigan where a lot of posted speed limits are 75mph. Then it's just raw gear ratios. Can't fix that.

 

I’m genuinely curious to find out how my last tank went with the I4. I’ll post up on Wednesday morning when I go get it and fill up. I was short on time when I dropped it at the airport. Entire tank on I5 but about 50 minutes idling in stopped traffic due to motorcycle fatality.

 

Sold my 19' golf alltrack MT for this new 22' TRD OR.

the alltrack was the top trim and had all the bells and whistles on top of MT. sonar, adaptive control, even assisted parallel parking lol (that was more trouble than its worth with the manual).




I'm going to miss the crap out of the golf but with this crazy used car market I know i would be getting maximum value for it only now (kind of like real estate pricing).

but now I got this guy!




shifting on the 22' MT tacoma is a lot more forgiving compared to golf in my experience.


I was weary about the lack of lock out with the reverse on the tacoma but its actually not a problem for me. I've actually done the accidental reverse in the golf because i pressed down while shifting to first. the tacoma really needs a forceful push all the way left to get into 1st.

but with manuals in modern cars with automatic backup cameras.

the reverse camera and screen turns on when in reverse anyway as a warning you’re going backwards.

 

Those golf wagons are sweet. My brother-in-law just picked up a 2015 TDI 6MT. It’s smooth as butter. Great value for the money too.

 

4.56 for the 8.75" is available right from Toyota, as some of the Hilux trucks received that ratio.

We can very likely adapt an RC series transmission to the TR engine, but time, cost, and low interest will limit that desire.

 

before the golf alltrack i had the jetta wagon (before it got properly named golf wagon) tdi in MT. i LOVED that car and still got 45mpg driving like a maniac.

even if it was FWD those tdi golf wagons drove so great.

the alltrack was FWD biased but you could really feel the difference when the AWD kicked in. i drove in some pretty gnarly conditions (8in unplowed snow).

i was scared about the lack of power and engagement i’ve read/seen on forums/youtube from this MT tacoma. but it’s been fine for me so far.

over taking in highways and city driving acceleration has been good.

it’s a truck i don’t expect to be sprinting off the line anyway.

 

I never liked cruise control in the past until having adaptive CC in the Tacoma.
With regular CC I felt like I always ended up creeping up too close to the person in front and have to drop down a couple mph. Then you end up falling way behind and have to bump it up a couple. And on and on.
With adaptive I like that I can set it a bit faster than the driver in front of me and it'll just hold me at a reasonable following distance.

 

The power is there, it just is so soft on the bottom.

 

All you manual climate control guys, go replace your home thermostat with this if you love it so much

 

Until adaptive has you driving 10 under because of the dolt in front of you and you don't know it. LoL!

 

I think if you liked the VW wagons then you'll like the 6MT Tacoma. They are deferent animals but both have great utility and are equally fun

 

I think for one thing 6 sounds better than 5 so 6MT makes the V6 more attractive and people pay the $ for it.

In the case of Toyota and not all other makes, our 6 speed wouldn’t make sense on the 4 cyl due to the relatively tall 6th. The 5 speed is similar to our 6 speed but without 6th.

on other platforms the 6 speed on a V6 is actually a more powerful combo, with closer ratios and not 2 ODs. 2 ODs is only a more recent thing. On my previous Nissan 6 speed the frontiers offer a 2.5L 5 speed and 4.0L 6 speed. The 5 speed is almost identical to the Toyota one in ratios. Most 5 speeds are that way anyways because they don’t have enough room to make any certain gear drastically changed since they only have 5 gears to work with. The 6 speeds basically have an extra gear and how they use it and where they put it deoends in the manuf. the Nissan 6 speed has a nice low 4.37 1st, medium 2.52 2nd, two 1.X gears for 3 and 4, 5th is 1:1, and a 0.77 OD. That was a fantastic and very performance oriented combo. To keep you from revving high on the highway they geared the 4.0 truck to 3.69. The close transmission ratios kept performance very nice still.

on the Toyota they have this half ass mindset of fuel economy that doesn’t really work in the real world anyways and ultimately ends up making a mostly useless 5th gear more than anything. There are times to use 5th but it isn’t really natural to select it in the upshifting process because it’s so marginal between 4th and 6th. It’s almost like they think they’re tricking us into lowering emissions by throwing an extra OD gear in there.
