since we are talking about MTL when should I flush my tranny. I'm at 52k on a 6th gen and I auto-x the car. It sees a lot of 6k shifts during the day as well. Recently I have had trouble putting it in 1st when its parked. Sometimes I have to tap the gas and gently ease off the clutch to get it in gear but its not everytime yet.

Should I put in new fluid and if so what type to get? If u say redline please specify exactly what product.
