Various Rover PG1 gearboxes have been used in the K Series powered Lotus Elise and the only way to identify them is from the serial number (somewhere) on the housing;
C6BP.... Standard box for Elise Mk1 and MGF
C4BP.... MGF VVC box (as standard but final drive 4.2)
B4BP.... Lotus CR box, Elise Mk1 111s, Elise Mk1 Sport 135 + Elise Mk2 standard box
B4BPU... Exige S1 (uprated)
B4BPQ... Exige S1 with LSD
G6BP.... Elise S2 111S

Gearbox Codes
The first letter is the gearset
c / 3.166 / 1.842 / 1.308 / 1.033 / 0.765
s / 3.250 / 1.894 / 1.222 / 0.848 / 0.649
b / 2.923 / 1.750 / 1.308 / 1.033 / 0.848
k / 2.923 / 1.750 / 1.222 / 0.935 / 0.765
m / 3.166 / 1.842 / 1.222 / 0.848 / 0.649
v / 3.250 / 1.894 / 1.222 / 0.935 / 0.765
t / 3.250 / 1.894 / 1.222 / 0.935 / 0.714
r / 3.250 / 1.894 / 1.308 / 1.033 / 0.765
w / 3.166 / 1.842 / 1.308 / 1.033 / 0.714
l / 2.923 / 1.750 / 1.222 / 0.848 / 0.649
g / 3.250 / 1.894 / 1.308 / 1.033 / 0.849
The number that follows the gear set number is the Final drive ratio
4 = 4.200 (15/63)
5 = 4.062 (16/65)
6 = 3.937 (16/63)
7 = 3.647 (17/62)
