automatic transmission

hi my name is gustavo and i am new in this site and i am 100% toyota consumer but i just bought a 2012 tacoma 4x4 and i think i have a problem with the transmission when it shifts from first to second gear it has a vibration or if you step on the gas you feel a great vibration if any of you guys have or had this problem please advise

 

Take it to the dealer it is under warranty.

 

Welcome and take it back to the dealer like the post above says. Shouldn't be doing that for a brand new truck

 

It's not in 4WD , right ?

 

i took it 2 times one in el paso texas and the other in roseville ca and they say that is under specs but the way it feels it is not right i am going to take it again even last time i drove it with the tech my guess is they do not have any idea of what is going on that is why ian trying to find someone with the same problem

 

no is on 2wd not even loaded

 

mine is doing it too under hard accelation

 

Check out this thread..... http://www.tacomaworld.com/forum/2nd-gen-tacomas/187518-2012-stock-tacoma-driveline-vibration.html

 

It's a common thing on these trucks and it's drive train related from what i understand, not the tranny. I've had mine for a few weeks now and i started to take notice of the vibration during acceleration from a stop, between 1st and 2nd gear and then it's smooth as silk after that. It's not always there for some reason and when it is i find it to be minor. Some claim that the vibration is really bad, i on the other hand couldn't get any vibration at all out of it today and i was trying with some hard acceleration to get it to vibrate. I was reading on here somewhere that some guy ran his truck for like a year or something and one day the vibration just went away, so maybe it's just a matter of breaking the truck in, who knows.

 

thank you for the the link and i used to have a 2001 jeep wrangler and ilift it 5 in and had the same problrm but that is fixed if you replace some part in the transfer case called slip yoke eliminator for what i know toyota comes with that slip yoke already but i am going to check it or bring hell to the dealer because as some one mentioned you pay 30 + k for a truck with this problems and as i mentioned before they have no clue at the dealer how to solve this problem because in el paso tx what they said they need to have several cases for the factory to get their hands on it but for what i saw this has been going for long time thank you for all your help and i will keep you posted on whats going on

 

By any chance some one that had this problem and change the gear ratio by accident
got it fixed. it just crossed my mind

 

I have a 2009 PreRunner Double-Cab short bed 4x2 (automatic) and it also has the vibration. Seems to do it when it's in first and getting ready to shift to second. Has done this since it was new. Dealer replaced drive shaft about a month after I bought it. They said it was out of balance but problem still exsists. Even brought it to a different dealer and they gave me b.s. story that it's "normal."

 

sorry for not answering before but i have been up to the yop of my head with work but this is the deal i took it to a diferent dealer and they ren some test my tacoma is 4 x4 and they remove the drive train it seem to solve the problem but they opened a case and i got a call from toyota they say they are going to get it fix i will keep you posted also went to dealer where i got mine and drove a brand new and it does not vibrate when shifting but if you get to a stop and give full gas it vibrates so my guess is that may be the rear axle has to much wrap i am goint to talk to the tech to see if he spots something

 

Thank you, I think it will be a good idea for me to call Toyota and open a case also.

 

Carrier bearing? Mine slips sometimes shifting into second but I'm supercharged...
