I just put a new GM 350 and a reman trans(auto) in a 1994 gmc k1500

I can push the pedal all the way to the floor, but it wont accelerate worth a damn until it gets into higher rpm's. Even then it does not seem to have much power...

any ideas???

TV cable?

fawked timing? Missing sensor connection? Hard to say from here.

 

[JeepsRcool]

any engine codes?

It is a '94 ....no TV cable it "should" be the 4L60E.

Like stated...timing? Did you set it with the brown (usually brown and under the dash below the glove box....on my '94 anyway) lead disconnected?

TPS check out OK?

This started when the trans was changed? Ive heard of bad torque convertors casung this, could have gotten a bad one.

is the engine revving but the vehicle not moving, or do you hit the gas and the engine doesn't go? Need some more info here.

fuel filter? I know mine sure came to life after I changed it. Was a night and day difference.

i had the same problem i replaced the torque converter made no difference but i eventually advanced the timing a touch off of the timing marks and it ran a lot better and tons more power
