Default tcm and spedometer not comunnicating properly
recently one of my vans went into a ditch and was covered in mud/water all over. It was all completely cleaned including all the undercarriage but my tcm and spedometer wont come back to life. Any suggestions?

The speed sensor should be on the tail of the transmission. That's the first thing I would check.
