Battle of the Transmissions: M/T vs. A/T

[Alexxmarcuzz]

Nasa’sayo yan kung ano mas trip mo. Pareho lang naman sila. Difference is may clutch yung isa. Yung isa torque converter. Pero pag dating sa mga paakyatan kagaya sa baguio, para sakin mas okay M/T kasi madisiskartehan mo pa pag namatayan ka or wala ka jumper cable. Kesa sa A/T hehe just my opinion.

Tatlo na kakilala ko na may M/T fortuner(1st gen) na iisa ang scenario sa Baguio, nawalan ng power yung mga fortuner nila sa ahunan kahit Anong piga sa gas pedal, lalo na kapag nawalan ng bwelo sa Traffic, pina check nila sa toyota pero hindi rin maipaliwanag ng casa kung Bakit, Hindi rin naman sira ang mga Scv nila at ok rin naman mga air filter nila.

baka driver error bro. kasi piga ka nga ng piga sa gas, di naman tama release ng clutch eh talagang mag stall ka; kahit anong auto pa yan.

pero nkakapag taka iisa sila ng scenario. Yung isang fortuner na actual ko literal na walang power. As in kahit pagalitin yung rev sabay bitaw ng clutch walang power umaatras lang sa ahunan kaya nilalagyan pa ng Kalso.

There are different types of automatic transmissions (torque converter, CVT, dual clutch). The dual-clutch AT uses clutches also, two in fact. Most modern automatics shift gears faster than what humans can do.

I have driven automatics for some time now and I never had any issues dealing with inclined roads.

My 4AT is 15 years already running at 140,000kms. Wala namang problema sa transmission kahit once lang yata ako nakapagpalit ng transmission fluid. So basically yung fluid pa lang naging gastos ko sa transmission, whereas kung sa MT in that period maaring nakailang palit ka na ng clutch disk/plate depende how much of a clutch driver you are.

it is how you use or abuse it.
my 2005 5MT is at over 120K km already. it is still the original that came with the car from the factory.
my 2003 4AT is over 100K km, and still shifts fine.

If usual route ma traffic then AT na, if open road most of the time, masarap pa din mag MT.

Well that' s odd. Are they well maintained? Overdue transmission or differential fluid replacement? O kaya paubos na ang clutch nila? Our Revo diesel has never lost power in Baguio at Kennon pa ako lagi. Climbs everything like a mountain goat. And we all know kung gano kakupad yan hehe

Yes nag tataka rin kame sabay kami pumanik yung innova rin namin na M/T walang bitin sa Baguio. by that time bago pa yung mga sskyan nila at casa maintained naman. Yung isa don nag be break in lang sa Baguio na disappoint din siya sa Fortuner nya simula non hindi na ipinanik ng Baguio.

Medyo odd nga. Most of the time it is the driver's fault.. Gas ba Fort nila?

Diesel lang ang manual variant ng Fortuner

Well, since mechanically exactly the same lang naman ang 2.5 na Innova at Fortuner, sa sasakyan lang niya talaga ang problema. Factory defect kaya?

I have driven 2 MT cars to Baguio. Both are considered "makupad" cars. There's the Revo diesel and also an Isuzu IPV. Makupad sa highway pero hinding hindi ako ipinahiya sa akyatan. Never even had to turn off A/C. So really, I'd say a vehicle with 80hp or so can already confidently go up to Baguio via Kennon Road, still with aircon on, at a brisk pace. [emoji38]

The Fort is heavier than the Innova by about 150 kg, but that's not the biggest reason why these MT Fort drivers had a hard time going up Baguio. I've driven heavier and weaker cars up slopes that are steeper than Baguio's.

The usual reason why MT drivers feel their diesel car is too weak is because they don't compensate for turbo lag.

A heavy car with a full load on an incline will be greatly affected by turbo lag (usually anything below 1500 rpm for turbodiesels). To compensate, you have to ride the clutch a little and make sure to launch above 1500 rpm from an inclined standstill. Most drivers simply release the clutch as they would on a flat road, which will obviously result in bogging down if done on an incline.

If you would observe an automatic in the same situation, the car would also launch at a higher rpm. The transmission is smart enough to know that the engine doesn't generate enough torque at low revs to have the necessary momentum. Most people don't notice since they just step on the pedal like they always do and it's the car that adjusts.

Ive seen a manual current gen montero that stalled while going uphill. Mga 60kph ata takbo pero biglang tumirik. Driver error ata. Mukhang napaaga ang kambya tapos uphill pa and turbo lag. the current gen montero's peak torque is unusually high at 2500 rpm kaya siguro namatay.

The driver needs to floor harder the gas pedal of 3rd gen mt montero in uphill to get enough turbo power in acceleration. The driver miscalculated his suv ability.

Agree with the lag on inclines. When I drove a relative's 2011 Carnival to Baguio, from a full stop it would actually dip if I didn't press on the throttle quickly enough. I think it was more the throttle response that was to blame than the engine response.

When we got a 2010 Carnival, I had a Unichip Q4 installed. Besides the power increase, throttle response was greatly improved to near instantaneous. I have yet to bring it to Baguio though.

But then again, the Revo has no turbo at all. And the IPV has a turbo that probably blows weaker than my nose. [emoji23] What gives?

Simple - because no turbo, no lag.

Ayaw nila magdownshift? 3000rpm is high?

Does this mean that during the "lag period" the turbocharged engine is actually worse off than a similarly sized NA engine?

With the Revo, I just have to release the clutch and it creeps, no matter the incline. I actually have to make more "timpla" with the IPV.

^ Old school diesels doesn't have fuel cut-off mechanism at very low rpm like those on crdi plus they have low gearing. Newer CRDI's you have to race the engine to keep the rpm, trans ratio is geared for fuel efficiency.
