I got a 88 Automatic Prelude Si and was wondering what my options are for replacing the transmission. I was having transmission issues with it where it wasn't changing gears at all, so much so that I couldn't even get it into reverse. I'm having trouble finding transmissions that would fit my vehicle. Any help would be appreciated to point me in the right direction. Thanks

You cannot use the 90-91 B21a1 auto transmissions on the 88-89 B20a5 motors, due to they have 4 solenoids, and the 88-89 versions only have 2.
The TCU will not know what to do with them.
