1--I felt the car's transmission was lagging a bit.

2--Really? I haven't felt anything.

1--Have you had the transmission checked?

2--I took it for a tune-up the other day.

1--The mechanic didn't say anything?

2--Nope. He told me that the car was in tip-top shape.

1--Would you mind if I took it to my mechanic? Just want to be sure.

2--Sure, go ahead. Would you like to take it right now?

1--Let me check with my mechanic.

2--If he is busy, then you can come back tomorrow. I am free.

1--He said he is free tomorrow. I guess I can come back tomorrow.

2--Great. Feel free to call me at any time.
