clunk when stopped at light.

Ok so my 2006 pre-runner does something strange when I'm at a red light or just waiting. I'll be waiting at the stop light and then the transmission seems to jump and make a clunk like I got rear ended. Its like its settling to find neutral or??? Could it be a torque converter problem? Has anyone had this problem or heard of this? Any info would help.
Thanks.

Never notice before had the truck since new

 

Exactly when does it clunk? Is it when releasing the brakes? That's how my axel wrap issue happened.

There are a number of ways to fix the axel wrap issue. I clamped my leaf springs at specific locations. That's the cheap fix.

 

x2...mine went away for a while...not its back

 

It sometimes happens when I release the brake and sometime just when I'm waiting to take off. Could it be a torque converter problem? I have noticed that the rear suspension sucks and it bottom out lately.

 

Actually same here i get it when im coming to a stop and when I let go of the brake

 

Yes we are in the same boat. Do you know what it might be?

 

Don't know why you are stuck on the torque converter. Everybody knows it's the leaf springs that is the cause. They start out weak and get weaker to the point the overload leaf begins slapping against the one above it. That's the clunk you are hearing.

I think your best bet is to replace your leaf springs. That will fix both of your complaints.

 

get some aals mine went away after i accidently installed my leafs backwards lol

 

lmao

 

Even when there is no load on the truck and just waiting at a stop light. would aal work or should I do something better?
thanks

 

it should work, i have toytec tsb aal

 

I don't mean to thread jack but today I just found out that my leaf packs were squeaking on my way to school!

 

to the OP:
a leaf pack may help...it did for me for a while but now its back

 

my shit clunked bad for few days after every time I let go of the brakes after a full stop. turned out to be a loose lower control arm.

 

I have had the same "clunking" issue. Coming to a complete stop or when I lift off the brake just a hair. Has been happening for two years. It almost feels like a transmission downshift.

I don't hear it as much as I feel it. Would axle wrap still cause this? Not sure what to tell the dealership to examine.

 

Mine clunked when I was stopped, normal. The other times it was just shit just moving around under the tonneau cover in the bed of the truck lol.
