Just had my 97 Tip 993 out for the first time and Had "check engine light" go on. My buddy hooked up his hand held and this is what came up :
PO740- TCC Circuit Malfunction
PO733- Gear 3 Ratio Incorrect
I thought maybe it was the old emissions fault but his hand held "passed" this function. How much trouble am I in now ? Any info is appreciated and hopefully something will go my way ! Thanks ,Steve
