My speedometer not working and car wont change gears (just had transmission,computer changed

If your speedo was working before, definately take it back to the garage. If your speedo wasn't working before, then your car won't shift correctly until you replace the speedometer. The ICU works off the info from your speedometer. If the speedo isn'nt working, then your car will not know when to shift gears............
