when i pull up to a stop sign and i give it a little pedal to take off fast it feels like the back of the truck is jumping or something is catching. Any ideas why this would happen

 

automatic or manual tranny?

 

Automatic .

only does it when i go to give it a little more pedal. if i take off slow it doesnt do it

 

possibly a u joint in the driveline, set the wheel breaks then crawl under there and wiggle the driveline and check it out, should be able to see the u joints good enough for a visual inspection

 

check you joints no play in them. I took it for another run and it seems like when you get on it it tries to upshift then studders. I read something about a govenor pressure sensor and a govenor pressure solienoid

 

How many miles is on the transmission?The studder could also be from low fuel pressure to the vp44 or the converter is causing the shutter in the trans. 47RE

Do you have a fuel pressure gauge?

 

is it lifted? could be axle wrap. have someone drive behind u and see if you axle twist when u take off.

 

Could be the rear end starting to go out. Or the tranny as said above.

 

i do have fuel pressure gauge nothing unusual there. I think its in the tranny cus there are some vibrations there. it only has 50,000 on tranny. I said hell with it taking it back to Bowler . Gonna have them check it out. Thanks for help
