I have a 1990 automatic civic that makes a that shifts kind of rough. I checked the AT fluid properly and its fine. I think it could be a mount but after looking online I found that their could be many problems with the transaxle itself. I'm pretty mechanically inclined and want to fix it myself avoiding buying a whole new tranny. I need advice how how to inspect it and diagnose the problem. I also need advice on how to fix it.

1990 Toyota civic
