I had a problem with a 2005 6speed SSR with 24,000 miles on it. I just replaced the battery and ground cable about a week ago ( battery was 6 yrs old and not holding a charge ) and I had previously replaced the ignition switch to the newer style about 4 months ago and all has been well until today. I was in line at the local high school, picking up one of my grandkids and shut the truck off in 1st gear while waiting.. When I restarted the truck and let out the clutch, it didn't act like it was in gear and the engine speed didn't change. I depressed the clutch again checked to make sure it was still in gear and still had no response. I glanced at the tach and it was indicating 500 rpm and when I pushed on the throttle pedal it had no affect on rpm or engine sound (top down). I was on a hill and just shut it off ( exhaust sound quit ) and coasted over to the side to get out of everyone's way. After restarting, everything was back to normal and clutch and all indications are normal now. I guess the engine must have died after start but the tach indication and exhaust sound gave me the impression it was running? The transmission was already in gear since it was not rolling while being parked on the hill without the emergency brake being engaged. Since the clutch and transmission are purely mechanical I cannot imagine anything being defective in that regard. When the truck failed to move the first time the engine rpm or sound didn't change when I let the clutch out and that is what made me think it was not in gear but I am pretty sure it was. I have put on about 50 miles since this incident with several starts and all seems normal now.
