Intermitant Neutral Problem

[RyanbabZ71]

Ok i have almost 22K miles on my truck. As of late this intermitant neutral (at a stop light i hit the gas and truck doesnt move then all the sudden it takes off) has been happening more frequent than in the past. Most recently today hit the gas truck moved slightly but felt like it was being held back. Then all the sudden it lunged forward and drove normal.

 

Anyone have theirs fixed. A definite fix? TSB? Parts used? Anything i think im gonna take it in soon

 

Thanks!!!

Mine does that too let me know what it is if they find something out.  Id have to fix it myself because it is out of dealer waranty.

Uh oh...I dont like the sound of this.  I also have about 22k on my truck.  Its only happened once, but enough to where I did notice it when it did do it.  How often is yours doing it??

Mine probably 2-3 times in the last 1-2K miles

 

Twice though it was very minor and felt it but it didnt last more than .5 second the other time today lasted a little longer 2 seconds.  

 

So far in 22K id say it has happened 10-12 times???

ya know guys, it almost sounds like you are just spinning your tires slightly and then getting traction.  im guessing thats not it, but it sure sounds like it  

[RyanbabZ71]

nope thats not it

 

Ok heres whats happens

 

I will come to a stop light.  Completely stop

 

Hit the gas engine revs truck doesnt move (tires dont spin).  Ill ease off the gas then hit the gas again and the truck will then go.  Feels like it locks up then unlocks

 

I wish it was somethig simple as the wheels spinning

ive noticed the same thing. i was wondering if the brakes were dragging.

[Z71GUY]

nah, if I had the same problem....the engine rev's pretty freely....like there is no load on the engine.  If the brake is dragging, I would assume I would have felt it in how the engine rev'd.

i think GM may be calling this problem a "lean fuel issue." i dont know why, or how to fix it.

[RyanbabZ71]

it has noithing to do with fuel.  You can feel it in the trans

I had this problem with my 99 Serria and the dealer replaced the throttle position sensor. The problem never happened again.

I remember this happening with my '00 Silverado a couple of times.  It feels like the tires are on ice for a split second and then all of a sudden they grab some dry pavement...  (I had 4k on it when I traded it)

Ryan, and everyone else with this problem:

 

I went to the dealer about this again, the first time "couldn't find problem", and the second time it did it when the service guy backed out of the parking spot they had parked it when I came in with it.  When I picked it up (it was in for a recall about a possible brake hose rubbing), they had ordered a valve body for the trans and a couple of weeks later, they changed it out.

 

It helped, but it still does it once every week or so.  It's not as "bad" as it was either.  It doesn't last as long as it did before, and the engine doesn't seem to rev as high, so there has been some improvement.  It's going in for an oil change, and I 'll stop by the service write area (in another building) and let them know about it. My truck is just about to hit 19K.  They have been totally honest over the past almost 20 years I've dealt with this dealership's service dept, with one exception, so I dont theink the guy (who actually did the work)was lying to me when he told me the pan was perfectly normal, and the fluid looked great, so I doubt this is any really big deal.  It's supposedly just some piston sticking, but since it didn't cure it.....????

Mine will do the same thing (16k on truck) most of the time it's just after I start it up, but it's almost like the truck is stalling.

Jon the problem we are discussing is when the truck is in drive and you stop at a stop light or stop sign.  

 

Hasnt reoccured since i posted this.  Very wierd how it does  it so rare
