hey got a 2000 grand prix 3800, basically car pops into neutral when shifting from 1st to 2nd. I release the gas, pump it a few times and usually it pops back in. It only does this with 1st to 2nd, I checked the trans fluid, its full. Theres no metal shards in the liquid so I knew I didnt bust the trans. Im looking for advice, help and a quick fix.
