Since you can't hear the engine, you'll have a harder time especially since you said the tach isn't working correctly. All it takes is practice.
Every stick car will drive different. I would be driving my Camaro all day and come home and get into my truck and it would feel so weird at first, the clutch and shifter feel is so different depending on what you're driving.
Learning how to drive a stick is a lot of fun, just keep practicing. I'm stuck with two autos at the moment and I don't like it. 99% of the time I prefer driving manuals.
