Guys, check out this thread on DSM tuners, it sheds some light on this very confusing issue:
http://www.dsmtuners.com/threads/resolved-transmissions-bar-codes-serial-numbers.114903
Last 4 Letters on the transmission code:
1st letter Final Drive Ratio
N = 3.545 ratio
W = 3.909 ratio
2nd letter gear ratios
O = dunno ratio?
P = dunno ratio?
Q = close ratio?
R = wide ratio?
3rd Letter Front Differential
B = open front diff
F = ?
G = ?
W = viscous front LSD
X = ?
Y = open
Z = ?
4th Letter Type of car it was used on. (Mounting locations?)
D = CB Lancer
E = CC Lancer
K = HH/HJ Galant
M = Galant
S = 89-90 Eclipse AWD 5spd
T = DSM G2
V = 91-94 Eclipse AWD 5spd mfg 6/90-2/94
Edit: Looks like "L" is one of our wagons, because both of my Summit transmissions had it.
