    Hello, I own a 2005 Chrysler 300. I moved overseas in Aug. and I left the car at my home in the states. A stabilizer was added since the car would be in storage. My son started my car weekly or at least 3 times per month. He did not drive it but rather just started the engine. In January, he reported that there was a puddle in my garage and it was later determined that it was transmission fluid. I returned to the states in June and had it towed to a mechanic in July. The fluid was still in my driveway so I was able to observe that it was still reddish in color and still had a sweet smell. Prior to this leak, I had no stalling, grinding or any signs that something might be wrong with the transmission. The mechanic has told me that I need to have the transmission rebuilt. I was confused because I didn’t have any other signs. I would appreciate your thoughts. Thanks

    You did a great job of preseving the mechanicals in your 300, no doubt of it. The only problem was that the transmission fell through the cracks. Most people assume, when they are laying their vehicles up for a time, that when you add the stablizers and other items, pull off the wheels and stack them flat and remove the battery that they have done all that is needed.

    That’s not the case as you have found. Over time, it is possible for your transmission fluid to go bad, if the vehicle hasn’t been driven — which yours hadn’t been. You see, the transmission fluid is an organic that can develop all kinds of issues, especially if you left your 300 in a warm, humid area. Not only are laqs and gums built up, but things like seals can become porous, allowing the transmission fluid to leak out. When that happens, especially if your car is not moved, the fluid continues to leak every time your car is turned over.

    At some point, your transmission is going to be nearly dry and that’s when damage occurs. You took the right precautions with your vehicle, except for a big one, it should have been driven, at least weekly, and brought up to operating temperature and then run for some miles. This would have kept the seals in good shape. It would have also kept the filter working properly as well.

    Instead, however, you let the car sit and rev which is not good because it not only builds up all kinds of nasty stuff that has no place to go but back into the engine oil and transmission fluid, but, the various systems never have a chance to keep turning correctly.

    I concur with the technician, you’ll need a rebuilt (it will cost too much to replace individual units).
