I recently ran into transmission issues with my 91 4 speed Ef civic. (Multiple bearings - squeaked like a barrel of squirrels). Honda technician found out the issue.

I thought about replacing the bearing completely but, I was offered a 91 Si transmission free of charge (PL3/3000).

I've done my research and to my great surprise it's a direct bolt in.

Well as I was looking over the Si transmission I noticed a crack in the bell housing.Looks like it may have been dropped.

I've included a picture. Will this be an issue? Or can I run it with the crack in it?

Thank you.

 

I was hoping to swap it in this weekend.

Any help would be appreciated.

 

Anyone?

 

your gonna need a better pic then that bro

 

How about this video?

personally id run it or you can always pull out the internals and swap it into your four speed case

 

Awesome thanks.
I'm thinking about having a piece to cover it.
Just so nothing flies in randomly.

 

id swap internals over... but covering it would be easier

 

run it. it was free

 

I would cover it and run it.

 

ya just cover it up and run with it if anything seems out of place then stop quikcly but swapping a tranny in and out is hella easy plus you can find them all over

 

also make sure if you have a 88 that the trans is a 88 or if you have a 89-91 you can use a 89-91 tranny 88s different

 

I have a 91' and it is a 91'si transmission.

 

Good luck swapping over the Si internals -> the 4spd case:

All from here: Gearset & Final drive compatibility among cable D-Series transmission cases

 

I'm just going to cover it.
Swapping the case would be a fun project. But I don't have the time to do all of that.
