Can someone with access to TIS post up the V6 diff ratios please?

Tunnie, you have it the wron way around; a 2.5 manual fitted with a 2.5 auto diff goes like a rocket because the auto diff is lower geared (4.22:1 compared with 3.9:1 for the manual). Fuel consumption is higher though.

I cant remember the 3.0 ratios, I think the manual is 3.7 but dont know the auto.


I think they are listed on the Eligable cars list, the leaflet scans on ABS

2.5 manual and 3.0 auto both have a 3.90 diff according to that so it should make no difference.  :y

So, for max acceleration (and fuel  ;Dconsumption) fit a 4.22 diff from a 2.5V6 auto to your 2.5V6 manual.

Better still, fit a 3.0V6 with the 4.22 diff. ;D
