Hi all,
looking to swap my motor for a type s because I have an Sh and want to keep atts. however the stock gearing is very tall and I'd like to swap the gear set from the T2w4 into the m2u4. Can it be done? My thinking is that since the t2w4 will bolt to a base block and the base and sh trans use the same gearing I should be able to swap the gears for the shorter ratios of the euro r. I dont need someone to tell me if they think its worth it, only if its do able. TIA

do you know the gear rations? :

M2U4 ATTS JDM Prelude Type S, USDM Prelude SH
1. 3.285
2. 1.956
3. 1.344
4. 1.034
5. 0.812
FD 4.266

T2W4 LSD JDM Accord Euro R
1. 3.285
2. 2.090
3. 1.481
4. 1.071
5. 0.812
FD 4.266

yeah I've been doing a lot of research. Theres lots of transmission threads and lots of digging to do but I cant seem to find anything related to this application.

try to figure out does ATTS have anything to do with gear rations/gearing

I dont think it does. Ive read that changing the final drive ratio could have an adverse affect I suppose due to throwing off the speed sensor. I just found that the audm m2r4 is an atts tranny with the exact same gearing as the euro r. finding one of those would be very difficult.
