Hello! I am new to the forum and thought I’d ask around if anyone is experiencing issues with their manual transmission? I own an O/R with just over a thousand miles on it. It seems to make a loud clanking noise when shifting in the lower gears, with the noise most prevalent when shifting into 3rd. I took it to the dealership and they said it was the “characteristics” of the truck. Since picking it up I have noticed that the clutch is starting to feel spongy so I feel like there is more to the issue. Any information will be greatly appreciated. Thank you!

I have a 2018 Sport MT with around 15K miles on it. Many folks have the opinion that this truck shifts a bit differently than other MTs, and the Accumulator Delete mod is a popular one for that reason. It just took me some time to get used to it but I love it at this point.

However, I definitely do not have the symptoms you're describing, and I would look for a second opinion. The last thing you want is to fuck up any part of the transmission on this new of a car. I'm not the most mechanically inclined, however if the pedal is starting to feel 'spongy' then it would probably be wise to check out the clutch master cylinder. Not sure if that's a separate issue or related to the shifting clank noise. You used the word 'clank'. Is the word 'grinding' also accurate?

No it doesn’t grind when I shift. It’s more of a slamming noise. It happens sometimes when I push the clutch in and also during lower gear shifts. Almost like I am slamming the truck into gear even though I am shifting normally.

I would highly recommend seeking a second opinion. Did you have the dealership drive it?

Yes we went on a drive. The person that rode with me said he could hear what I am talking about. However it was the shop foreman that said it is normal. I made another appointment with the dealership.

I've had 3 of the new gen, all with the manual transmission. None made any odd noises or had any clutch issues. They shift quietly even without the clutch. My other vehicle is a Honda with a manual so the standard is pretty high for ease and smoothness of operation. I would try another dealership if possible, or ask your current one to drive your truck and another new one back to back, for comparison's sake. If it's "normal", they will both be the same...
You could remind them that it's not a "characteristic" you would have purchased had it been like that when you test drove it.

Update: I went back to the dealership and had them take another look with me. They still said the vehicle is operating under normal conditions so no fix. I’ll monitor it and continue to do research.

Sorry for the disappointing issue, but it could be something besides the transmission. Maybe the tranny mount bolts are loose or something else like the leaf spring eye bolts (89 lb-ft), and Toyota has a ludicrously low leaf spring u-bolt torque value like 37 lb-ft, needs to be 80 lb-ft like a real truck. I would go through and torque stuff, checking torque is actually in car owners manuals.

i've always noticed mine clanking. it's more noticeable driving offroad. i always thought it's another reason why the shifter shakes so much.

New to the forum as of today.

I realize this isn't experience from a Tacoma, but it's similar. Coming from a 2014 Jeep JKUR with a 6MT and a 4.10 gear ratio, I know what you're talking about. I experienced similar clunking/slamming the first time I drove it off the lot and still experience it today. I found that I had to be very deliberate in my shifts (i.e. not being lazy while shifting or with the clutch) and in some ways had to learn how to drive the transmission, not the vehicle. It is finicky and it was more difficult to drive than any other manual transmission I have driven. My coworker has an almost identical jeep and said the same about his transmission. It's a pretty common characteristic of the MT Rubicons.

Generally, it seems to be how these transmissions are, particularly with the gear ratio and engine - it has a lot of low end torque. However, I've had no transmission problems with my Jeep for the past 6 years.

I have not experienced the clutch feeling spongy in my Jeep.

I'm waiting on a 2020 TRD OR MT. Covid-19 put a damper on that. Hope to pick it up in the next month or two.

A little update:

I picked up my 2020 TRD OR MT about two weeks ago (May 30th) and have about 700 miles on it now. I have noticed that it does sound/feel a bit clunky when shifting from 1st to 2nd and from 2nd to 3rd, but mostly 2nd to 3rd as @Kevin_kl pointed pointed out. For me, this is a result of how I'm driving rather than something with the truck. If I take my time to let off the gas, put in the clutch, shift, let off the clutch, and give it some gas, all is good. However, if I'm driving it like a race car and hastily shifting/clutching then I hear/feel the clunk. Same thing I experienced in my MT Jeep Wrangler.

I have not experienced a spongy clutch.

Slow is smooth. Smooth is fast.

I had the same issue and same response from dealerships on my 2018 TRD OR. Now I'm at 30k miles and need a clutch replacement, which the dealership also will not cover because it's outside of warranty.

I recently drove my buddy's 2019 TRD OR MT and his clutch feels smoother and more consistent than mine ever did - and definitely no clunks.

Hello everyone!

I recently purchased a TRD OR MT and I am having exactly the same problem as the OP, "clank" noise when shifting from 2nd to 3rd (downshifting from 4th to 3rd does not make the noise). I took to the dealership back with just 50 miles on it and they are saying that is not a problem and it is "normal". I'll appreciate any suggestions or advice.

One thing that I noticed is if I double clutch it, the "clank" does not happen.
