    Newbie with transmission issue

    I recently bought my first Mopar, a 2005 Magnum with the 3.5L V6.
    I really like this car, but one day last week it was revving quite high (2200 rpm at 40mph). Today, it did it again, and when I stopped at a light, it wouldn't start moving when I accelerated. I shifted to park, then drive, and it was OK after that and the rpm was where it should have been.
    Any help would be greatly appreciated.

    Check for codes.
    Check the fluid level.
    Maybe drop the pan, change the filter and refill.

    Could it have been going into limp mode?

    First and foremost, check the fluid level -- classic low fluid behavior.

    How do you "check the fluid level" without taking it to the dealer or using an aftermarket kit?

    Assume you have same setup as on the Hemi's -- no dipstick. Practically any shop should should have an appropriate dipstick and be willing to check for you for the price of adding some fluid. The process take all of a minute or two.

    I don't think it's in limp mode, because I was till able to drive at 100-110 km/hr, but the revs were around 3000-3500. I did notice when I got home that the engine light was on, so I will check the codes when I get home tonight. I just thought it strange that it was ok after shifting to park, then back into drive. I was also able to downshift manually, so it was in 5th gear.

    Thanks. I'll do that tonight as well as checking codes. I just bought the car, so I really don't know if the maintenance has been kept up. The engine light came on as well, so I didn't know whether it would be the engine or transmission. I assumed the transmission because after putting in park then drive it was alright.

    Does it only happen when you first start it up, and then after the first drive, it's fine for the rest of the day?
