Hey everyone, I need some guidance cause my hands are tied behind my back here. I have a 2015 Civic Si I recently purchased a new Exedy clutch and rear mount and had it installed at my buddies shop which is 4 hours from home. During the installation, he put 5w-30 Mobile 1 in my trans instead of MTF - red flag one. On my 4 hour journey home, I noticed a throw out bearing sound but quickly brushed it off thinking it was just the upgraded flywheel. Shortly after, when I was cruising in 5th gear around 40-45mph, it would just randomly pop into neutral. I thought it was the shift linkage rubbing on my HPS intake heatshield so I just avoided 5th gear until I got home to remove heatshield. 2 and a half hours into my trip home, I was just hanging out in 6th gear at 70mph when all of a sudden, the car falls on its face and catches itself. Then does it again and TPMS System flashed and my entire dash went crazy. I put the peddle down and the RPMs were just dropping. As I was pulling over, the slower I got, I could hear my car whining at me from my clutch/transmission area. I came to a complete stop and shut off the car all the way. Gave it a second and when I went to restart the car, it wouldn't start. Would continue to crank and crank. Awesome 2 hours from home, I had to get a tow to my house which was expensive, after just installing a new clutch. While we were loading the car onto the tow truck, I had to sit in the car and push the clutch in. Even when the car was in neutral, it wasn't rolling. Would only roll if the car was in neutral AND I have the clutch pressed in. When I got home, I tried to go through the gears since I didn't do that on the side of the road. The car will NOT go into 1-4, goes into 5, 6 and reverse. However, if I try to push the car in these gears, it goes nowhere. I HAVE to be in neutral WITH clutch pressed in to roll car. So, now I'm not sure what the best plan of action is. Is my transmission broken? Clutch popped cause failed install? Oil seized my trans? Why won't car start? The only thing done to the car is intake, flashpro, 4 bar map sensor and now this clutch which i assume is shot already.
