6 speed manual transmission

This is my first time to drive a truck and got a new 2008. Every time I change gear the rpm take long to reduce before I shift to another gear. Is this normal or something wrong this happens since I got this truck.

 

its normal, its the Drive By Wire system

 

Hi,
If this is normal so I can shift to another gear even the rpm is still high? By the way shifting is smooth no problem.Thanks for the info.

Yeah I noticed the same thing when I got my truck a couple of weeks ago. I just figured it was because it had a heavier flywheel then my old V-dub. I don't know what this drive by wire deal is.

 

Klown is right, it's kind of weird until it breaks in, try to hold your shifts a little and then change around 2200-2300, but don't do this under a heavy accelerator, nice and easy.

 

Raffy,
I have the same thing on my 08. At first I thought it was just me but I had a few others tell me the same. And I didn't tell them anything about it. I also noticed that the rpm goes up when you brake. Close to 1500 rpm. It does it in neutral w/ the clutch out, light braking, and heavy braking. If you keep it in gear until about 1000 rpm while braking...you feel it "surge" and when you do push in the clutch it goes up until you just about stopped.

I tried resetting the CPU by disconnecting the neg. batt cable. It actually got worse! It does settle down after a bit but WTH!!!.

Another observation is that it shifts normal when cold, like right after you start it up in the am until it warms up.
I've driven stick all my life and never experienced this in any car.

I don't think any of this is normal. I'm starting to wonder if we got the cpu for an automatic. Which now leads me to another question.


For those of you w/ the Scangauge 2, does it read what flash/firmware you have? Just interested in making a comparison.

 

My buddy just bought an 08 Accord with a stick (sweet little car) and his car holds the revs when shifting as well so it is not just a Toyota thing

Maybe this is the next generation of manuals. I am cool with it and have adjusted.

 

it does that because our trucks try to constantly "learn" your driving habits and they try to adapt the obdII computer to maximize fuel burn and timing hence the "VVTI"

 

It gets better over time. My 06 has 13,000 and I don't notice it anymore.

 

The reason the revs "hang" between shifts is because of the programming of the ECU. It's programmed that way for emissions reasons. It's not the flywheel, or the full moon, or the brand of gas you use.

 

This is one of the biggest complaints I have seen with the manual trans.

My issues with this went away with TRD CAI as well as TRD exhaust. I attribute the cause to excess back pressure. when you decrease this 'back pressure" the rpm's drop as soon as the clutch is depressed.

 

Is your exhaust the whole unit or just the muffler, I heard they don't make the whole TRD Cat Back for our trucks anymore. I may be confused,
but yeah, I been driving stick for 14 years and my 08 witn 1k mile on it does it too. It is starting to smooth out now, thinkin of getting a CAI and Exhaust to help this prob as well as making it sound better. yeah I revived the thread!

 

I noticed this also.It is nothing like my last manual vehicle(79 Z28) but I am used to it now.I think I am moving the gear lever earlier in relation to the clutch being fully pressed.Ofcourse one must get off the gas without delay as well.

 

My gear has problem engaging 1st and 5th speed, I installed the TRD short shifter a little better but problem still exist, anybody else?? Oh went througth the thread didn't find any related topic

 

well my 05 with now 71000 miles has gotten better as time goes. it takes time to get use to, its an electronic accelerator with no gable. 2 nd gear is always a bit rough the rest goes very smoothly. good luck

 

its probably keeping the rpm's up because ur shifting, to help gear transition so as not to create to much shift shock going into or coming out of another gear. the ecu also is able to read clutch switch (this may also be how/why its able to do it). also when u brake -there is a vacuum line to brake booster -engine reads vaccum and maintains rpms, especially if clutch is pressed again (during downshift). just my $.02

 

Reading through the thread I though Klown was back for a minute
