I have a 98 Honda accord ex manual. I had to replace the tranny because I lost 4th and 5th gear. I just got everything back together and tried stating it up. When I start it, it immediately revse up to about 3800 rpm then drops to 200 rpm and dies. Sometimes it starts for about 10 seconds running at about 100-200 rpm then dies. I’ve checked all lines and plugs atleast 8 times, no lights have come on and I’ve scanned no codes. Before I did the swap I drove it as it was with no issues besides the tranny and I never got any codes then and the engine ran smooth
