2004 chevy venture shifts into drive but will not move unless you rev it up then it engages and moves
Check your transmission fluid level. If its low fill it to the proper level. Then look for a leak. If it looks like cherry kool-aid you're fine. If its brown and smells burnt get it flushed. I recommend BG brand.
Did that friday night trans fluid drain changed and filter still will not move unless you put it in drive rev it up until it engages then you can drive once it cools done start all over
I've had quite a few of the GM mini vans over the years. I hate to say but your transmission might be toast.
