MT Accumulator Delete Mod (ADM) and BS Thread

I have a 2nd gen, that's why the link goes to the 2nd gen forum. Your thread is the most recent in regard to the topic at hand, but in 3rd gen section. Just to keep things separated and where they belong.

No clue if the 2nd G v6 has one. That thread seems to point to 'yes'. However, it could be trans/engine related thing. Or a 5spd vs 6spd thing. Looks to me that's more of the difference.

 

Anyone with a 2016+ 2.7 MT care to crawl under their pig and take a gander?

 

Or someone could take a look in the 3rd gen service manual... I don't have it on my computer at *cough* work

 

You're welcome. Complete success in my book. I am planning on checks of the safety wire every once in a while. It is stainless steel, but . . .

Yes! It is COMPLETELY normal to drive. Those two changes have transformed it. I really hope that anyone who feels that their MT Taco is a bit wonky can get these two mods.

The 4.0l have them. That is why I was posting there. There seems to be a few different designs for the clutch lines looking at the OEM parts website. Some had flex lines coming into the accumulator and others seem to have more slack to be able to bend and connect it the way that was posted in that thread. The 3rd Gens need something at least as big as the elbow to even make the connection.

Mr @7r41lbr34k3r has a 2.7 MT. He might know?

 

My slave cylinder is likely in the same spot as you guys. 2nd and 3rd gens.
I visually followed the hard line out the slave to a bracket on the bell, to a soft line with bracket on the frame, back into a hard line running up the firewall. Into the cab, assume the master cylinder at the pedal. There was no gizmo chunk of metal lookin thingy along the route.

 

I don't know if my 2.7 has an accumulator. I just assume that it does, because my clutch feel is crap as well. Normally it doesn't bother me, but when I am towing and starting on an uphill grade it can be a pain to compensate for 0 clutch feel ... all of that with the annoying throttle lag. I would definitely do this mod if I end up having one.

Right now I just blip the throttle up in the above situation (seemingly takes forever), and then go on pure muscle memory for the clutch feel. I am glad to have had a lot of practice before having to face this towing situation. It was interesting enough learning how to drive it smoothly with no added load. It felt quite weird to me, and the last time I owned an automatic was about 20 years ago.

 

That's excellent. Yet again, I'm mystified by the reasoning, design, and now implementation of it. Makes almost zero sense.

On ours, it is next to the slave. Both the slave and accumulator are hard to see with the heat shield in place. Only the bleed nipple sticks out for us.

You can see where it is in relation to the slave in the seventh pic down in the OP.

 

That is the feeling that I had, except that the OEM and upgraded ECU tune has always been great for blipping. Sometimes a bit too aggressive? That has not been everyone's experience though.

I'm self taught with over 20yrs of ownership as well, plus some fun on friend's and relative's cars / trucks before that. For smooth shifts for me, it isn't a constant motion to engage the clutch. I slow down the motion once I feel the friction point / take up and then proceed the rest of the way out, as feels best (sometimes fast, sometimes slower). The accumulator seemed to make that into a wave which sometimes ends up with light bucking, esp in situations where I am matching large differences in flywheel to input shaft speeds (getting going quickly in 1st, high RPM 1st to 2nd, downshifting into 2nd and 1st, and dealing with the tall reverse gear).


I will say this, not having towed yet with the new tune, Reverse has become very acceptable. Much less slipping in parking situations.

 

Did Toyota include the 4 banger in their update?

OVtune has promised to work on a tune for the 2.7 dual vvti, but they seem to want to dedicate their time to 3.5L development. That is certainly what will pay the bills, considering it is wayyyy more popular, so I don't expect to see that any time soon.

 

do you still have the return spring in? because if this delete mod achieves normal everything then I'll have to reinstall the return spring for peace of mind in the cold season. mine is currently removed.

 

Sorry, but no. Only the 3.5s seemed to get attention. This is what is noted in the firmware file:



I would say to hold out for an OEM update, but that is really hard to recommend given some of the responses that folks are getting after calling corporate.

 

Yes. I tried the spring delete, but for whatever reason, all that it did was make the clutch much heavier with no additional feel. I'm definitely not an athlete, but not small in the legs either. It would have made stop-n-go or fun roads miserable for me.

I am not really surprised that it didn't feel heavier for you with some of the other inconsistencies that have been found. Or, you don't skip leg day.

 

that's funny. I'm sitting here in the gym now. it's leg day.

thanks for the reply. and thanks again for sharing all this.

 

I need to follow your example. Dammit!

No problem! My pleasure. TW has contributed a ton for me.

 

This will all be pure disappointment I fear. Rather spend $400 on a header.

 

That is what I am gathering today about OV, shame really.

I do already have the LCE header installed, which I love. 400+lbs of steel and fiberglass added to my truck and I am right back where I started though .. haha.

 

Edit.. Didnt read before I made a post.

For those who done this, does the clutch grab earlier?

 

No worries. I fixed the title to work.

With out the accumulator, we get more stroke on the slave. That said, I almost feel the engage point is a bit more toward the middle of the travel? I'm still evaluating.

The only other 3rd Gen that has done this that I know of is @RedBeard1 ?

 

This thread is mostly about aliens.

 

I just don't like that 4 bangers get shit on. In all aspects of the Tacoma community and it's vendors.

I can't help it that people made poor decisions and bought unreliable v6 trucks lol



-I'm joking people, and a bit of a crude ass. Sarcasm is fun.

Serious note: @7r41lbr34k3r what's the difference of the LCE and Doug headers? Any pdf or charts you can hook me up with? LCE site shows the Doug claimed gains, but nothing for their own product.
