I have a 1992 saturn sc2. When using sunpro scan tool it displays trans. Codes 34 & 47. Also when check engine light is on there is no speedometer. When you clear the check engine light with scan tool the speedometer will work again and car runs fine. As soon as light comes back on there is no speedometer car run and shift lousy
thank you mark
have the same problem?
