Jerky acceleration

Hi friends, I have a 10 Tacoma TRD Sport 2wd and lately I've been experiencing jerking while accelerating. The jerking only occurs when I'm constantly driving within 40-60 mph. It would occur about 3 to 4 times for about a split second then everything would go back to normal. 8 months ago I had the tranny fluid changed. Since this occurs when I'm hitting the gas, I figured it was a throttle issue.thought it was the throttle body so I cleaned both throttle body housing and MAF cleaner. However it started again after a short test drive. Not sure what the issue is. Anyone experienced this issue, please advice.

 

If you believe it to be transmission related check this thread, it's a good writeup about the 2nd gen automatic.

 

Could be your
Throttle control module (at the pedal) we are fly by wire for throttle
Throttle position sensor

Check for codes (dash light doesn't always come on when a code is stored)

 

Another thing that could cause a jerk as you describe is a missfire.

 

The truck isnt throwing any codes. I changed out all 6 plugs when I first got this truck last February.

 

From the replies it seems like a torque converter shudder issue, throttle control issue, possible fuel pump or a possible misfire. The only thing is that this truck isnt throwing any codes. I heard there was a TSB for torque converter problems with these transmissions.

 

Also possible fuel pump

I had a 92 GMC that did this and it turned out being the pump

 

Mmmmmmm............deer jerky

 

I'm going to run to Autozone and have them check

 

I also considered this a few months ago as well

 

Do you have a mechanic you trust?

Doesn't hurt to spend a few bucks and know for sure before spending money in hope of fixing (been there done that wish I hadn't)

 

TCC shudder and ignition miss can often feel the same, usually you can differentiate them by watching the tach, if it bounces up and down when the jerk occurs it's likely TCC shudder.

 

Excellent advice. There are two local mechanics that used to work at Toyota. Since it could be a factor of 3-4 issues, it's best to let a mechanic figure it out since I'll just be spending to trial and error.

 

My tach remains stable with the jerky feel. Therefore it may not be this then.

 

For sure

I sold a truck because I thought the problem was big. Saw the truck two days later for sale for three times what I sold for.

Yeah
I'm still kicking myself for that one

If you take your truck in and they find problem. Post the repair so others know if it happens to them.

 

I will definitely keep this post updated with my findings

 

Update,
Today I did the 120k maintenance along with rear differential fluid. I also added Lubeguard Instant Tranny Shudder fix and Lubeguard Tranny Additive. I drove it 5 miles and noticed improvements

 

Hi, I'm chiming in because my 2010 with 100,000 miles started doing this. It would jerk between 40 mph and 60 mph while driving on any incline, but it happens randomly and not throwing any codes. I drained and filled my transmission fluid twice already at 90,000 miles. Just wanted to check in with you if that additive you put in has fixed your problem permanently?
