Harsh downshift

[cboggs]

I have a 2002 Sebring Conv.

I just changed the trans filter (70,000) miles and now I have a very harsh downshift into first gear. (No problems before the trans service).

Any help would be appreciated.

Thanks,

C.J.

well i own a 1999 JXI convert and mine does sometimes(Once every 2-3 weeks?) do that as well. I have heard that is a almost normal chrysler thing once the cars/transmissions get older so i dont worry about it. Unless urs is doing it regularly,i wouldnt really worry about it.

I have been doing some research and it appears that I put the wrong fluid in trans.

I used Dextron/Mercon like I have done for years with Chrysler vehicles but apparently in 1999, Chrysler made a change that requires a synthetic fluid ATF+4.

Using anything else will cause a harsh downshift.
