Default y1 (with broken case) gears into a hydro ls teg trans for my ef

I have a cable y1 on my b16 sedan and the casing broke due to a nasty pothole i didnt see coming all gearing inside is fine and I have a hydro dc teg trans which I want to swap in however I would like 1st 2nd 3rd and 4th out of my y1 and the long ls 5th for freeway driving. I also want the y1 diff as i have read it is stronger then the ls one. Is it possible to use the y1 parts inside an ls hydro trans? NOTE** ( a cheap cable trans in the NM area would work to.)

Any advise is appreciated

I know there is a guy on here that put his ys1 guts into an itr hydro case... I don't know how much different the LS case is though.

y1 is a b16 tranny with a 4.2 final. i dont believe you can swap gears with a hydro,only the ys1 can swap gears with hydros

before you swap transmissions you would need to get a cable hydro conversion for your car. there are two options

http://www.passwordjdm.com/pro...D=469

and http://www.innovativemounts.co...41001

basically one uses a master cylinder and one doesn't..does anyone have any experiences with of these pieces? i'm looking to go hydro in my ef..

Default older tranny

You cannot put Y1 internals into a hydro transmission. See this post: https://honda-tech.com/zerothread/1979069

You need a LS 5th gear -- it has to come from an Integra 90-91... which I believe is no longer available from dealer (there's a 5th gear write up archived here that the writer indicated he bought the last one in North America? Do a search)

You can try to find a 90-91 5th gear and a spare case, or both (a USDM S1 gearbox) to work with the parts you have. Or you can scrap it all, and get a YS1 case and get some vtec internals swapped over into it -- unless you can score a VTEC YS1.
