@Jason Preston Our transmissions have four gears, not five. (Second person that for some reason thought the transmissions have five gears. Wonder why they think that?)

 

was using that as an example/ like on a manual transmission

 

TC lockup.

 

That's what I figured, but I always knew that the TC lockup was it locking up, and not a gear change. (Had a 1994 Cavalier that we had to disable the lockup mode by disconnecting something, because it wouldn't go out of lockup mode. A mechanic showed my brother how to do that.)

Ah, I didn't realize you were using that as an example.

 

lenn "rocket forward commensurate with how I’d expect for how hard I was pushing the throttle" I had this problem and changing the TB fixed this issue.

 

mine does this and its related to vct issues.. maybe clogged.

 

I just recently bought an 04 FX4 with 75K miles. When i got it i thought it was a dog with how slow it accelerated through the first two gear, but chaked it up to me not being used to the truck. However after reading this is sounds like i may have a similar issues. When i take off from a dead stop the truck gets up to around 3k RPM's shiftings into second and feels like someone attached a trailer to the truck. If I get in the gas more it feels like the motor finally catches up and finds an extra gear.
