Hi George, OK, It seems like the filter should catch this if any came loose.?? The reason I have been using silicone is that whenever I have done these services to a transmission is that the factory has always used it when sealing the pan the first time. I guess it must be a different sealer than what I used. Can you tell me what I need to do to correct the problem?

To late this time but just so you know for the future, you must NEVER EVER use that type of sealer anywhere near an auto trans!! regards George. ----- Original Message ----- From: "Bruce Naimy" <brucenaimy@xxxxxxxxxxx> To: "zzChrysler 300 list" <Chrysler300@xxxxxxxxxxxxxxx> Sent: Friday, June 16, 2006 1:52 PM Subject: [Chrysler300] 300M Down Shifting Hard Hi Group, I just did a transmission service on my 2002 300M and now it's down shifting hard from 3rd to 2nd when slowing down at normal speeds (around 30mph). It feels like a downshift with the Auto-stick. The service I did was to drop the pan, change the filter and gasket, and refill (5 ½ quarts) the transmission with ATF plus4 fluid. I did not flush or drain the torque converter. I was careful to remove the old "o" ring and replace it with the new one provided. This was the first time this car has had a trans. service (53,000 miles). I have serviced a 98 Concord and a 99 300M transmission several times without incident. The only thing different this time was that the fluid is a newer style. I did use silicone gasket sealer on the gasket that came with the filter as I've always done in the past. Is anybody able to guess what's happened? Thanks, Bruce Naimy Hurst 300M [Non-text portions of this message have been removed] To send a message to this group, send an email to: Chrysler300@xxxxxxxxxxxxxxx For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm For archives go to http://www.forwardlook.net/300-archive/ Yahoo!
