Hey guys I am wondering if a crx si tranny will fit on an 89 civic 4 door? The reason I am asking is because I founf one with a bad tranny but the motor runs good and I have an si tranny in my garage. Thrying to make a little extra money, you know

 

yes, bolts right in

 

What year Si tranny. Must be 88-89 for it to work with that 4dr.

Count the splines. I beleive it's 21 for the 88-89 and 22 for the 90-91.

 

Its an 89 tranny also
