I just spent $658.22 on a EGR flow valve on my 2007 mazdaspeed 6 with 55,000 miles on it. This after two years of complaining about a shutter right before turbo boosts. Now im having difficulty getting the car into 1st gear and 2nd gear. Took it to the dealer “can’t duplicate”. As im driving away from the dealer I grind 2nd. Took it back to the dealer, went down the street with the service manager and grinded 2nd gear again. The service manager says “I’m shifting too slow”. Im really concerned all Mazda dealers are waiting for warranty to go bad before they repair anything. Powertrain warranty is up at 60k something tells me im going to pay for it. Can someone shine some light on why im having difficulty in 1st and 2nd gear?

Does the clutch pedal seem to engage close to the floor?
Check the clutch fluid level.
I would suspect the clutch master cylinder.
