I purchased a 1983 Honda Civic Dx 1500 with a 5 speed manual transmission for $450. The head was warped due to overheating and took the car off the road. I pulled the engine apart and resurfaced the head since it was warped and im gonna put it all together. The 3rd gear from this transmission doesn't go into 3rd gear at all according to the old owner. I'm looking to either swap the transmission or rebuild it, whichever one is the cheapest. The problem is that I can't find any rebuild kits for this transmission or direct replacements for the whole tranny. I'm kinda stuck so any input for my situation is welcome
