Is it possible to transform a parameterized SQL query into LinQ to SQL?

Hi everyone,
 
Is it possible to transform a query with parameters into LinQ to SQL (keeping the parameters in tact)?
 
This is what I have so far in plain SQL.
 

SqlCeCommand trans_comm = new SqlCeCommand("SELECT DISTINCT transmission_type FROM vehicles WHERE make = @make AND model_name = @model AND model_year = @model_year AND engine_type = @engine_type", conn);
 
            trans_comm.CommandType = CommandType.Text;
            trans_comm.Parameters.AddWithValue("@make", makeComboBox.SelectedItem);
            trans_comm.Parameters.AddWithValue("@model", modelComboBox.SelectedItem);
            trans_comm.Parameters.AddWithValue("@model_year", yearComboBox.SelectedItem);
            trans_comm.Parameters.AddWithValue("@engine_type", engineComboBox.SelectedItem);
            trans_comm.ExecuteNonQuery();

 
I want to transform this to the equivalent LinQ to SQL syntax, keeping parameters in tact, if possible. My main concern is that I want to prevent SQL injection, if possible.
 
This code works fine as is, right now.
 
Thanks everyone!
