2018 tacoma sport manual transmission issue

Fluids aren't going to affect clutch slippage. Old hydraulic fluid or MTL can affect shift quality.

@Tacomatrd420 try cruising in 4th around 3k RPM and flooring it. A really bad clutch will slip under those conditions.

 

I would start with that . If it needs a new clutch oem is the best route imo . If u are hard on your clutch and it takes a beating than after market would be a better route . Otherwise overkill .

 

Clutch slipping in the middle gears is a classic sign of a worn clutch.

In the drive train you have 2 points of slipping between the engine and the ground. They are the clutch and the tires. Between those you have the transmission which is a torque multiplier. When you take off in first gear your engine has very little torque off idle so the clutch doesn't see much stress. It has the transmission behind it to multiply torque and you can still easily spin the tires. Also in 1st gear you go thru the rev range so fast there's really much much time for the clutch to slip even when the engine produces peak torque. As you shift up thru the gears you get less torque multiplication after the clutch is the clutch now sees more stress and nit the tires.

3rd and 4th gear is where you do most of your acceleration and the engine is in it's peak torque range longer.

By the time you hit 5th you are usually up to speed and not accelerating much with the engine below it's peak torque.

Just imagine riding a regular 10 speed bicycle. The pressure you put on the pedals is what your clutch feels. When you pedal off in 1st you really aren't applying much pressure to take off. Even if you did the crank speed increases so fast you can't keep up applying the same pressure.

Your clutch is done. Now you just have to figure out why so early. It could just be from your learning experience. There's always the fear of stalling or trying to get a smooth shift so you tend to let the clutch slip more on every shift.

 

idk man, it sounds like somethings off. @bigoldbeef has like 350k miles on a stock 3rd gen clutch, i think. and $3200 sounds insane for a clutch swap

 

I probably do slip abit more than i should, this truck has been the trickiest for me to be honest, my dads camaro and the fiat 500 are/were smooth, i assume its done, 1300 ishfor the oem clutch alone.

 

Also sounds like a slipping clutch to me. At 50k KM roughly 30k miles, that seems way too early. Then again driving habits come into play. Do you ride the clutch? Who else in your family drives the truck?

 

370k now

 

As much as i didnt want to like this post i had to. I went to a dedicated transmission shop today after work. Hes going to look into upgraded clutches vs oem and availability. The symptoms almost disappear after its warmed up good tho. Its still very drivable if i shift around 4k and accelerate it grabs fine into the other gears but if its lower rpm i get slippage.this all indicators of a clutch that toasted. Ive noticed as more ppl mention it, i do seem to be abit slower disengaging my clutch, so sorta riding it abit. I live in the langley bc canda and its stop and go city traffic. I guess its a learning curve, i understood the assignment when purchasing a manual, still love it tho, fun truck to drive.

 

Most likely bad habits lol shitty but oh well, no one else drives my truck, been offroading a fair amount with it too so i assume that may play a factor in an early wear, for me at least.

 

still towing?

 

Following...

50 k miles on 2018, I can report no issues with my manual, sorry to hear of yours @Tacomatrd420

 

Yeahh im assuming its a clutch and just my shitty learning,as ive been paying more attention to it today, it seems i do tend to ride me clutch abit. Mental notes i guess. I feel like its more my shifting betwen gears some im not releasing it quick enough, oh well, I guess I learn one way or another lol expensive but ohh wellll

 

It is only 30K miles. I believe he quoted 50K km.

I have owned 7 vehicles that were standard shift, 3 were pickup trucks with heavy offroad and hauling usage. None needed a new clutch before 100K miles.

Generally a new clutch should last 100K miles with proper driving habits, but there are flakey clutches out there. Mazda B series had repeat issues with the throwout bearings wearing fast. Did not affect clutch lifetime much, but gave a grinding noisy and squeaky pedal travel.

 

Yes, my first brand new 1992 Toyota 4x4 truck with that 3.0L and 5 speed, had the original clutch and no signs of issues when I sold it with 230,000 KM's

 

So from what i can understand i glazed the clutch pads whilst towing a coworker out of the snow. So not a warn out clutch, just a costly fuck up lol

 

yeah that might have done it

 

Didnt think i was supposed to be in 4lo, guess i learned the hard way. Oh well ‍. Is that a repaired clutch or replace? Can glazing be cleaned? Like with a flat block or file? Probably better to replace since its coming out anyways

 

yeah better off replacing it while you're in there even if repairing was an option

 

Is this root cause analysis based on clutch disk inspection?

My personal experience is that I have heated clutches to the point that you can smell them (terrible smell) countless times in my life and yet I have never replaced a clutch disk.

EDIT: 4lo is proper for pulling. 4hi will burn your clutch super fast. Trucks with automatics can get away with pulling, climbing obstacles, etc. in 4hi, because they have a torque converter, but manuals cannot. Our trucks have a dry clutch that is not bathed in oil like a wet clutch on a dirt bike. Ya gotta baby ‘em.
