Question about 2002 Chevrolet Venture Passanger

Synchronization problem between accelerator and transmission at low/no speed

2002 Chevy Venture - 76,000 kms - regularly serviced

From a stop or at low speed, there seems a transmission issue when applying sudden acceleration e.g. crossing a busy street from a side street by "flooring it." The engine revs up but there is a brief moment with no forward thrust, then a sudden engagement (not smooth ... more like a lurch). Likewise, if driving @ 15 kph, any slight acceleration results in a hesitation and lurch forwards.
There are no codes or indicator lights signalling a problem with the transmission, sensors, or module; and at speeds above 30 kph there is no hesitation or "lurch" between applying power and acceleration. My mechanic says there is no problem, but it feels like there is a weakness at low/no speed acceleration, and I don't wish to damage the transmission.

First thing, hopefully your mechanic checked, transmission fluid level. These are horrible for transmission issues and for intake gaskets! I owned a 98 and put way to much money into it. The egr valve had to do with exhaust gas recirculation, not applicable here. There is (or should be) a hose going from your intake manifold to your transmission that helps the trans shift at the right time. Find this hose and check for leaks. Had the transmission been serviced ever? Fluid and filter changed? Is either bring starved of fluids or vacuum, I'm leaning toward vacuum myself.

Low oil pressure light comes on in 2003 chevy venture?

Oil level? Last time serviced? Oil filter changed? Number of miles? Regular service as required by Owner's manual? Otherwise if none of these are a problem, you may have a failed or failing oil pump. Worst case is bearing problem.

97 chevy venture does not move when accelerator pushed

Sound like it could be low on fluid which would cause this and if so would indicate a leak somewhere. could also be a sensor that is bad or could be that transmission needs to be replaced. hope info is helpful and if so please leave rating on this post and good luck.

My 2002 chevy venture roars when I speed up. when changing gears there is a little **** sometimes and a noise . I hear a different noise yesterday, like a motor running when i speed up and the sounds...

it doesn't matter what it could be. you need to get it looked at before you end stranded or break something expensive. Its the only way to know for sure.

check your transmission fluid levels they may be low, and replace the spark plugs you know give it a good tune up! wires, air filter, fluids, clean throttle body, IAC sensor, check for Vacuum leaks; like cracked hoses that lead to your map sensor or EGR valve etc.
