Jolting forward when stopped???

2006 TRD Prerunner Access cab.....

Every now and again i am stopped at a light waiting for it to turn green or whatnot.....and my truck "jumps" forward slightly. To clarify, it seems someone pulls up behind me and just bumps into me.

Like the tranny is trying to "engage" for a split second......maybe?

I don't know if this has happened to anyone else, but it seems to come and go for me. I have taken it to the dealer to get it looked at and they had me drive it with a mechanic to try to duplicate it.

But with no success....

I cant make it do it, it just happens.

HELP ANYONE?!?!?

 

push the brake harder.

 

Ive tried that....still does it

 

Your truck is fine, and the jumping is normal. There are a number of threads on TW discussing the issue. You'll find them if you search enough.

 

Turn the a/c,defrost off.

 

Yep your truck is just reving up with the A/c mine does it to. Just push a little harder.

 

Why would that cause it?

I usually drive with windows down and no air going at all.....but i cant say it has/hasnt done it when i only have the AC going...

 

Here's a recent thread by a guy complaining about guys complaining about the lurch. (Don't take that personally - I'm just linking it b/c it speaks to your issue.)

None taken....

Im not very mechanically inclined....so i dont know what would cause this or why or whatever.

I just thought it was weird that the dealer couldnt tell me why....supposedly professionals.....

and i wasnt assuming a recall or anything like that. This has happen since i first got the truck. My dad noticed it before i did only cuz i got my truck before i got my license. haha.

Thank to everyone though.

 

It only happens this much

 

subway 5 dollar footlong? haha

 

Something that might help:

Every now and then backup in a straight line and then slam on your brakes. That will help the auto-adjusters on your back brakes adjust out. Seems to even help the pedal be a little firmer.

NOTE: You don't have to slam to hard. Also make sure there is nothing behind you that you could hit.

HTH

 

he's not saying it only happens that much... he's saying, "This is as far as the lurch will take you."

 

someone told me found his issue to be the slip yoke on the driveshaft slipping back (harshly) into position. he greased everything back up, and it hasnt happened since. i personally dont have clue, just posting up heresay.

 

yea mine will do that every now and again

 

Mine does it as well.

 

6 speed manual- problem solved.
