    Hi all!

    Posting for my cousin who owns a 06 Gran Prix GT.

    Recently his transmission has started acting up. He said it was slipping a few months ago and had the fluid and filter changed, which resolved that issue. Now about a week ago it started to act up again. He says when coming to a stop itll shift into neutral then force itself into 1st. If he rolls through a slow right (IE a yield sign or parking lot condition), itll shift into neutral as he turns but upon accelerating again it will not re-engage the gear for a couple seconds then slam 2nd.

    He has no other issues but those. Says it drives fine 10mph and up, drives through the gears without slamming, all 3+OD work, etc.

    Any guesses? I did a search (trust me, im no forum n00b) and did not find anything relevant to his issues.

    Has he checked the fluid level at full hot/in park/idle on a level surface? Could just be low.

    Good call!

    Apparently he was the one that did the fluid change/filter. Says the place he called said it only took 4qts so that's what he put in. Guy at the shop said it was low and that it takes 7qts? Either case the shop filled it to proper levels and my cousin says its drives perfect now.

    Guess you guys can mark this as resolved. Thanks!
