I read where the 03+ got the 5R55S tranny, but after checking an OASIS on my LS, it shows different. Any ideas?


OASIS RESULT:
1LNHM87A23Y65XXXX

VEHICLE INFORMATION
VEHICLE DESCRIPTION
2003 LINCOLN LS BODY STYLE
4 DR SEDAN
ENGINE 3.9L DOHC EFI
TRANSMISSION 5R55N AUTOMATIC
AXLE CODE 53
ENGINE CALIBRATION 3LQ18S0A
GENERAL WARRANTY INFORMATION
WARRANTY START DATE 01/03/2003
BUILD DATE 12/19/2002

think they switched in mid july of 2003. so if your build date was prior to then you got the crappy N like I did:)

Anyone know the differences in the two trannies? I have searched and found information about clutch packs, clutch engagment sequences, etc.

I know the description of n vs. s means synchronous and non-synchronous. not sure what the net result is. maybe the s doesn't fail all the time????
