In the mornings when I start my truck and dont really let it warm up, It tends to lundge forward pretty hard when I put it in Drive.
I also feel it shift a little hard from time to time ..

Its an 05 4x4 with 86K . Any ideas what can fix this ?

 

Let it warm up and the idle become normal... not to sound rude, but it's common sense. You have to let vehicles warm up to prevent that

 

Have you ever changed the fluid?

 

No I havnt, Ive only had the truck for a month or so. It might be something to do soon. Just so that I know whn it was done.

Thanks Truck guy, I normally do, I guess I just feel it more on the truck than other cars ive had.
