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] ------------------------ Yahoo!
