    when putting into reverse for the first time

    on the initial start of the day, the gearbox grinds. As if the clutch is not pressed. The transmission fluid was changed over the summer. Any ideas???

    I get that too. I don't know if it is because the gear oil is thick or if my clutch is wearing thin.

    Low fluid level, gearbox worn, air in clutch hydraulic system.

    or clutch dragging with pressure plate, which may have oil on it. Always shift into reverse directly from a forward gear (with the car stopped, of course), and this won't happen. When a gear is engaged and the car is stopped, the only thing turning in the gearbox is the input shaft, so you can shift to any other gear, including reverse, without grinding.

    Yes, or any forward gear

    The forward gear synchros will stop the transmission gears from turning, and also stop the clutch disc, if it was dragging along with the pressure plate. A quick shift from the forward gear to reverse will engage reverse without grinding before the gears can be dragged up to engine speed again by the clutch. It makes no difference whether anything is hot or cold.

    Because your car seems to have a dragging clutch only when it is cold, you might use a forward gear other than first gear to stop the dragging. First gear synchros take the hardest wear anyway, and there is no need to burden them with this additional cold-start task.

    Alternatively, you can start the engine with reverse already engaged, but then you are asking the starter and ring gear to break the clutch disc free from the pressure plate.
