My recently bought a high mileage 2001 Sebring with a recently rebuilt transmission. Fluid is nearly new of course but my concern is the rebuild shop likely used some type of "Universal" fluid and not the proper ATF+4 when they filled it, unfortunately a common affliction with Chrysler products. I don't think we're going to be able to actually find out what was put in the tranny due to the work having been done by the previous owner. It runs fine now. Since it's new I want to protect it by getting the proper fluids in it. My son has no money either so I'm going to suck a bunch of the ATF out with my Liqui-Vac and refill with ATF+4. Past experience tells me I'll likely be able to get 4-6 quarts rotated doing so. We'll rotate it again in a month or so. Here's the question: Since I can't get all the ATF out right away, I plan to also add Lubegard to it, but I can't decide on the classic Red or Platinum for this application. From what I've read, if I were certain it didn't have ATF+4 in it I'd use Platinum, but I'm not certain although my suspicions are likely well founded. In the off chance it did have ATf+4 in it I'm afraid the Platinum might cause problems...but the Platinum is clearly intended to upgrade lower fluids which is exactly what I need, I think hah hah. I'm leaning towards rotating the 4-6 quarts and using Red, then doing the same again in a month or so. What say you Lubegard users?
