An H22 trans will bolt right up. No issues
That's incorrect, it the SH trans (Atts) it will not work with the F block. The SH22 (as I like to call it) block is slightly different on the rear side (transmission side) and rear block when bolting it to motor itself.

He wants to put the SH on a base H22 he said,and swap the entire h22 in the 6th gen..Would the tranny mount be different still?

Forgot to specify this is for a Accord that already has an base H22 swap, however to concensus seems to be that the SH tranny will not fit the base block, I do have the SH block too but it's not in working condition. Having it rebuilt would cost too much en even then I do not know it the ATTS module would fit inside the Accord bay, can anyone confirm ?

I believe the ATTS is the entire steering rack also,so I dont think it would work.?

I guess I should of checked more, I bought a whole prelude just for the Tranny and turns out it's an SH. OK provided I really didn't pay much for the car, but I have to sell the Atts tranny and find another Prelude or Base transmission. Buying on a whim is never good, altough so far parting it out as yielded really good results

OK here's a long shot.

If I have both transmission: Prelude SH's (M2U4) and Accord's (P2A8), can't use the M2U4 directly because the Atts won't fit the 6th gen. Could I use the P2A8 and swap out gear 1, 2 and 3 (keeping gear 4 and 5) to get the gear ratios of the H22 engine in the correct housing ? I don't suppose it would be that easy ?

IMO the M2B4 or T2B4 is better choice, (LSD too) I have an M2B4 mated to my JDM H22 and a buddy of mine here has a T2T4 in his 92 accord with JDM H22. Very similar gearing. I wouldn't waste the money on trying to do all that gear swapping. Just sell the trans and get a non sh trans.
