I'm in the process of buying parts for my SS > 5spd swap. I'm working on a pretty good deal with someone; he's selling his SH tranny w/ atts unit at a good price.

From searching around it seems as if the SH works fine w/ the ATTS unit removed. If I'm installing this tranny onto my Base 'lude, can I just simply discard the ATTS unit?

I haven't been able to find a jdm h22 tranny or base 5spd tranny at a decent price.

 

You have to use the ATTS with the Type SH tranny and since you have a base block there will not be the mounting holes for the ATTS and your oil filter will be in the way. Keep looking for a base tranny or even better a 4th gen VTEC model tranny. There are good deals out there if you look hard. I found a base tranny with only 15k mile on it for $400 last year.

really? I thought I would be able to remove the atts unit and just get a base 5spd intermediate shaft to take its place.

 

I am interested to know this as well. I have a friend who is seeing how the conversion from SH to a base tranny will work.

 

Assuming you're not going to be using the ATTS unit for obvious reasons. The SH tranny will bolt up just fine to the base block, but you're also going to have to change the differential in the SH tranny. The SH uses an interesting looking intermediate shaft(one shaft inside another kinda thing) which will only couple with the ATTS unit. So if you want to use the Base intermediate shaft, you're going have to get a base differential. Basically get another tranny, SH stuff is useless...

 

How about converting an SH with a Base tranny. What in all would be necessary to get this job done? ECU, tranny, intermediate shaft, anything else?

 

and you got to fabricate the mounting plate that is attached to the block.

Look here for details

Thats awesome man. Thanks for the pics.

Is that plate the only other thing? Is there any differences in the harness?

 

Every 5th gen is wired for an ATTS unit, so no, no difference in the harness.

 

Thanks man.

This has been good information.

 

Yeah thanks for the info.

So a Base 5th gen intermediate shaft wont work with a SH tranny w/ the ATTS unit removed

 

correct, it wont work. All the SH stuff is junk other than internals. If you remove the atts and tranny there is still a big hole in the block unless you fabricate that mounting plate.

Its a major PITA to do anything to a type SH, trust me, i know.

 

When the SH guys toss the ATTS unit, what intermediate shaft are they using in its place?

Basically, I have a base auto and just bought a sh 5spd but removed the atts unit, just wondering what i should do

 

I think an h23 intermediate shaft is what you gotta use along with a different transmission. you cannot use the SH tranny without the ATTS. Get a base tranny then do the whole plate thing.

You bought a type SH or you bought an H22A4 with ATTS?
(motor or entire car)

 

Just bought the SH tranny w/ atts unit. I was hoping I could just remove the atts unit and use the tranny with my base 5th gen. Im trying to do the Auto to Manual swap.

 

the SH tranny is worthless without the ATTS unit. the connection on the driver side will NOT work with ANY intermediate shaft other than the ATTS unit itself.

 

Actually, I just looked in the service manual, and the little mini shaft on the SH tranny that hooks up with the ATTS unit can be taken out, in the case of rebuilding the tranny or taking it apart. So I think u can just take that little piece out, and a regular half shaft will fit in fine.

Thats what I thought. I've heard of the SH guys removing the ATTS unit and using a h23 intermediate shaft in its place.

 

well they must be doing somethign pretty special cause neither accord NOR prelude intermediate shafts fit in the type-s atts tranny i sold a while back.
the ATTS tranyn WONT work with a standard intermediate shaft.


i know this as i have several h22/f22 transmissions, halfshafts, an ATTS unti from a preldeu type-s and i USED to have teh type-s transmssion as well...i sold it since i didnt feel like using the 90 lb halfshaft of non functioning atts unit.

 

okay, thanks a lot for all the info. I guess I'll see if I can source a Base 5th gen tranny
