90 hb B16a1 swap


Junior Member
Hey guys,
I need some help. My friends and I did a B16a1 swap to my 90 civic hb. It runs great, but there is a grind when shifting from 2nd to 3rd gear. It grinds all the time in high revs and once in awhile while cruising in the low rpms? Does it mean I have a bad tranny? I'm going to try to change the fluid over next weekend to the syncromesh fluid by chevy.

My friends is that same way. I hope the mesh stuff works for you. He hasnt tried anything to fix it yet, along with his eratic idle, and distributor thats going out on him.
