Short answer, dunno!
Longer answer, would think same, given how the dif ratios react between the two.

Ineresting. Though.

i started wondering last night when i saw my ar35 that'd turned up on a pallet: is there a difference in ratios? Are the TC's the same between ar25 and 35 and what makes the 35 able to take more torque? Why not fit just ar35's on omegas, they'd only ever need the 35 for the entire range

I seem to recall the Ar35 being slightly longer geared than the AR25 (from memory based on fitting AR35's into TD's).

The extra strength is due to the extra clutch plates within the box.

thanks for the replies, in theory then only 2nd gear is more robust :/ still don't get where the 100nm comes from

This would suggest that the 4 pots have different ratios. Not sure about the shorter 1st on 2.6 MV6/Elite. Looks like a typo to me.
