I was wondering if anyone knew exactly how the computers work that diagnose problems in engines/transmission etc. I brought my car in w/a list of issues and some being related to that but I don't know much about transmissions/engines and couldn't 'identify' the problem. So im wondernig how these work and if they will be able to tell everything thats wrong with my car. TIA!!

An OBD-2 Scanner can read all codes stored and a simple run on the street will tell exactly what is going on. EVERY sensor in the car can be monitored by a scanner. Too bad you aren't closer or I could scan it for you for free (or a beer or 2!). :p

autozone can also read codes like the svs or ses lifghts
A mechanic can tell you what the prob is with your tansmission and stuff like that.
Unless the problems you are having are throwing codes, the scanner i dont think can tell whats wrong with your tranny or engine

some $300-500 range code scanners are capable of detecting a lot of engine/tranny problems, even when the check engine light isn't on.... the one i have is called Autoxray 5000....its upgradable for new codes, plus it reads obd1 & 11, and it is enabled for the new computer restrictions, which wil be released into the market in 2007, mandated by the government.... that scanner cost me about $375, plus upgrade each cost $50.....

Or you could save a few hundred and get one of these that does the same thing:


Auto X-Ray and AutoTap are both WAY overpriced!
