Weird jerk after stop - Page 2 - TundraTalk.net

Mine does it too.. but so did my Titan, and my Chevy lol.

Just about all leaf sprung automatics do it. Its a combination of the tranny dropping into first, and a little bit of axle wrap.

My 2008 Tundra with only 11k takes too long to go from Reverse to Forward, back out of the driveway into the street and need to move fast and 2 second lag before it goes into gear. At cold start the engine roars to life with almost 1500 rpm. Don't tell me that is correct either. Everyone says it normal and get used to it. My throttle is also very over responsive and not smooth. I am not happy with how it performs at all. I also get to a stop and roll thru at 1 or 2 mph and get that high rev when I take off. Like the trans is old and worn out and slow to downshift. 1st gear should not be so low that it does that. The Gear selector drops so fast that I miss reverse and go to neutral or farther. Miss Drive and go to low. Like there are to tabs to engage it. Where can I find a list of TSB's so I can go over them and get all this repaired? I am sure the dealer will not volunteer to do it unless I bring it to them. I do not use the truck a lot and it will be out of warrenty time long before the mileage runs out and I will be stuck with all the repair bills that normally would be covered under the warrenty. Thanks Bill

Ok, but....

My 2010 is jumpy at start up for the throttle, but gear shifting is nuts on...

i have this tiny little bump, you can feel it in the brake pedal, like right after you stop if you let the brake off it does it or if you are dead stopped and hit the gas, i thought maybe the spare tire was loose and was bumping around a little bit but i checked it and it was very snug

Bill P · 02-22-2011, 02:03 PM

A tiny bump you feel could be fuel moving forward and back in the fuel tank. I had a van that you would feel doing that at about 1/2 a tank of fuel while stopped at a light. When full it would not do it. Even with baffles the liquid still moves. Bill

Blushin, I can feel the same thing you are talking about. In high school I had an old 1989 Bronco II that did the same thing every time I would take off or come to a stop. I finally got tired of it and took it to a mechanic. He said it was a bad U-joint. He replaced it and I never felt that bump again. It feels like the exact same bump I have in my brand new 2011 Tundra. I have less than 3,000 miles on the truck.

blushin · 02-22-2011, 02:18 PM

yeh it does it sometime but not all the time, its not like a bad feeling dont get me wrong, its no crazy jerk or anything , just feels like when you come to a complete stop, if you take your foot off the brake for a second it feels like something is releasing. sometimes i notice it and sometimes i dont, my truck has 45k on it right now

Chris G · 02-22-2011, 02:23 PM

Yeah I know what you mean but it annoys me. It doesn't feel like it should be there to me.

blushin · 02-22-2011, 02:24 PM

yeh me either, i just bought my truck about a month ago, and it was certified and everything so im sure its fine, might have the mechanics at my dads dealership take a look at it when i go in for my next oil change

Bill P · 02-23-2011, 08:54 AM

I am not sure why Toyota puts such a low gear ratio in the rear end and does not offer any option. Mileage is bad enough without having a 4:30:1 ratio and would improve if a 3:75:1 was an option, Towing limits would be lower though. If a low first gear and diff ratio is a factor that contributes to the lurching forward. I do have faith in Toyota and was tired of too many early repairs on my previous truck a Dodge 2500. Also I do not like the fact that the trans is sealed and you cannot check the fluid level or condition. I like to keep my fluids checked. Bill

hey so heres an update for you all, my dad has worked for Lexus for the past 18 years. Last night i had a conversation with his Lexus corporate representative, who is actually one of my dads close friends, he told me that they have the same issue on the Lexus GX suv. he said it has to do with the drive shaft loading up, its normal on all these trucks, also i asked about the sealed trans and he said they did that so you wouldnt have to worry about fuel levels, trans and diff fluid is supposed to be changed every 30k.

i took my truck in for a tsb/ ecm udate for my 4.6.

guy said theres no fix for the bump.

so dumb

cookiedough1 · 02-25-2011, 06:37 PM

It also doesn't hurt to grease the zirks in front and back every so often like I'm guessing at least once every 10-20K. That seems to help a little of the driveline clunk at a stop when letting off the brake and lightly stepping on the gas going away from a dead stop, the tranny would hesitate and take off/lurch forward not smoothly.
