Just a quick thank you for sorting out my car ahead of schedule.
Even with all the heavy traffic on the M1 the car was totally different.
I forgot to ask, is the overall gearing now the same as a 6ltr VXR Monaro?
Anyway all jobs done to top quality... as ever

Regards John

3.9 diff?

Yes, and a rear end pack at long last!

Yes it is, but the 6ltr Monaro has the short ratio gearbox, my CV8 has the tall gearing,so are they the same?

Shamelessly pasted from granada's thread ( here):

GM Vin	GM	Tremec	Ratios
Designation	Part no	Part no	1	2	3	4	5	6
MM6	92067136	TUET2100	2.66	1.78	1.30	1.0	0.74	0.50
M12	92155485	TUET2066	2.97	2.07	1.43	1.0	0.84	0.57
M10	?	?	3.01	2.07	1.43	1.0	0.84	0.57

MM6 * (3.9/3.46) is like stepping to:
2.9983
2.0064
1.4653
1.1272
0.8341
0.5636

So pretty similar to an M12

Was thinking vxr8 for some reason!

Cool, glad you've felt the improvement, always better that way
