Lurching at stops

Hey wonding if you guys can help me out.
I have a 2008 Tacoma Prerunner DBL cab 4.0l auto and it lurches pretty hard while waiting at stop lights. I have searched on here and found 1 post on it with no info other then others have felt it also. Has anyone figured out what it is or better yet how to fix?

 

a/c compressor.

 

idle kicks up as A/C compressor kicks on........ Easy enough to make sure its just that. No fix for it except leave off A/C and make sure your on the brake?

 

This plus/or get yourself some sexy rear leaf springs from wheelersoffroad.com or All-Pro

 

Exactly, my 08 did this, my 11 did this, haven't noticed yet in my 15' but its been cold as f.

 

Thanks guys!

 

There is a fix for this. Search for defrost or A/C wire mod. This will allow you to have windshield defrost on, but without the compressor.

How fast do you come to a stop??

With my own truck.... If I come to a stop quickly, the lurch is from the transmission downshifting after you come to a complete stop.

 

He's talking about the engine being under load while stopped with the a/c on.

 

Yes it after im stopped, while still stopped it will lurch forward. makes sense that it would be from A/C kicking idle up. But cutting off power to compressor will kind of negate the defroster. Will do a little more checking and just have to deal with it.

 

Lurching at stops? Sounds like your truck has AFS

Better get it fixed on Wednesday or it might Fester

 

Yoi still get hot air, just no a/c removing the water from the air.

 

It lurches forward, cause that from all the horse power trying to escape!

 

I get a similar lurch without the A/C on.... lots of threads about this.

I've had a similar lurch without A/C on.

 

I wonder if this is a symptom of the transmission being low on fluid?

 

I didn't notice this in my 12 tundra or my current 12 taco trd sport but,My 05 tundra and my 01 Sequoia lurched as well dealership said it was down shifting as well no real fix

 

I don't know but if you are stopped and the truck is lurching/pushing forward, I would think the torque convertor isn't releasing like it should when the brakes are applied. Perhaps a weak/stuck solenoid in the transmission.

 

I can't remember when...sometime in the last 8 years of owning my truck (mine is an 07)... I had the dealer check the transmission fluid. It was fine....

I don't think its much of a mechanical issue (per say) versus an ECU program thing.... Perhaps they've fixed the situation in the newer trucks??

The Op has an 08...??

 

Ive had it happen too on older vehicles with the trans downshifting maybe 3 seconds after stopping, just a symptom of age and wear i think. How many miles on this truck? Have you used to tow anything very often?
