came up with ce code p0604 ram error . anyone had this problem and is it dealer fix ?

If p0604 is the only code set, the TCM (transmission control module) will need replaced. It indicates an internal failure of the module.

If you do end up working with a dealership, charlie40, please let me know as I would like to be available to you through the process.

All the best,
