2014 tranny wont shift!!!

2014 tacoma with only 3500 miles randomly wont shift from 3rd gear no matter how hard you accelerate! Some one have any idea whats wrong with it before i take it to toyota tomorrow?

 

I don't know what the heck could mechanically go wrong that quick on a 2014

Maybe a vacuum line got knocked loose/off?!

 

It won't up shift when cold under certain conditions.
We need more info than u provided

 

Sounds like a transmission valve body issue, maybe some solenoids are bad already.

 

It was driving normal! I stopped at a light and when i when i took off it shift fine all the way to third and it wont shift to forth! I looked all around the tranny and i cant see anything out of the ordinary.

 

Its about 60 degrees outside and i had been driving for while already.

 

Ok don't take this the wrong way.
Are u sure you were in "d" ?

 

If it's cold it won't shift into drive until the engine gets to a certain temp, which is around 120/130 range. This normal...

 

will it at all skip 3rd altogether or just you get up to third and there is no higher gear?

Still sticking with valve body

 

I get ti third just fine but wont shift past

 

Yes i was in drive! Thats the first thing i check as i was driving!

 

Ok when u bring it in and it's doing it do not shut it off. Ask someone to go for a drive. They should throw the scan tool on it and see wants up.
Shutting it off may mask a hint to what's up.
Good luck

 

well keep us updated on what the dealership finds out.

You could go to AutoZone and have them check codes...sometimes a transmission issue will throw a error code in the ECU. Unsure if you can have their diagnostic tool check error codes in the TCM, but you could ask.

When your driving does the gearshift still display "D" mode or the gears and your transmission shifts through them or is it blank? is there a wrench icon displayed in that location?

 

My friend and I went wheeling one day;
On the drive home, he couldn't get into 3rd; just like you said: wound it right out - refused to upshift

Got home and got under the truck... vacuum line got knocked off
This was an old Cheyenne with a Turbo 300... but, same thing may apply

 

My dad works for toyota so he'll get it taken care of for me. Just was trying get some info.

 

Don't let anyone else touch it. Don't read codes, don't pull battery.
Some generic code readers have cleared codes and or info simply just by using them. It's new. Let the dealer handle it

 

Hmm ill go take a another under the truck and see what i can find!

 

Ahhhhh ok.

 

Took another look under the truck and still cant see anything wrong! Must be internal! Off to toyota tomorrow

 

Modern transmissions are electronic.
There are no vacuum lines running to them anymore.
It is either an internal hydraulic problem or a software glitch.
