Re: Trans and motor not listed on spid

I did some research on spid errors and from what I can tell you is no one typed the spids. They used the some kind of machines to type them and distribute them for people to put on the trucks. Not shure on all the details. I can tell you there was not a person typing the spids. Errors still could happen though. Like turbo hydra matic would be spelt wrong or something like that. Here's a link to the one I read.
