Ok I have posted something on this site before on how I just purchased. My first H22 motor, now as happy as I am it was a 2000 H22A4 SH motor. Little did I know that it has an ATTS system incorporated with it . Which is not a friendly swap into my 5th Gen Accord. Wish I would have done the homework first you know. But anyway so I came to you guys for help and I was told that a base model H22a tranny would bolt up. So what does Alex go and do I bought a base model 95 H22a M2A4 tranny so my headache would go away. Still a little new at this I investigate some more and come to this now ( " The SH has a different block, it's a fact. That's why the SH and Base trannies is not a bolt on swap. Internally they are the same, but the block design on the outside is different. Intermediate shaft and tranny mounting, oil filter and a bunch of other stuff. " ) I found this info here Base vs. SH
What is basically being sad is that it would be cheaper for me to dump my bottom and get a base model H22a bottom. If I were to do that would I at least be able to still use the H22A4 head that came with my swap. I know I should have done the homework first but the price was right and I just did one of those compulsive buys, which is now smacking me in the face. I now turn to you guys once again for help which I really need right now I don’t know what to do please please please help me.
