Good point about the shifter. As part of your appointment to fix your grinding issue, insist that they also readjust your shifter as part of the work.

Your shifter could be set-up incorrectly.

 

You are also in Florida...only two seasons there, Hot and rainy

The gear grinding/clunking seems to happen more in colder weather where insufficient warm up before driving causes issues.

 

Thanks for all of the suggestions. We'll see what the dealership says when I bring it there in a few weeks.

As for the insufficient warm up before driving, on really cold days I let it run for a few minutes before driving, plus I double clutch or just start in 2nd gear for the first 10 minutes or so. Even after all of that, the first normal shift into 2nd gets a grind. I even tried the suggestion of rowing through the gears at the first few stop lights, didn't make a difference. I can live with it if I have to, I just don't know how much damage it is doing to the transmission.

I'm glad I got the automatic. I read about too many issues with the manual to want to deal with it plug a bad left knee makes driving a manual painful after a while.

Newbie question: why can't I pm?

 

GM has the same problems in the cold weather. (The Camaro is having fits also). It is inherent to the transmissions of this era. Most come with heavier weight oils and in cold weather are too thick. Trucks, cars, imports, its the same. Some do shift better than others, but in the end, a lighter weight oil in the gear boxes (rear diff also) in cold climates is what is recommended by the manufacturer. Just have the fluids switched for your climate, and be happy with your Mustang. I have synthetics in all my Fords, and additives in the rear differentials. I've never had a problem since I first did this many years ago. (When it's -20 outside, you want to be able to roll as freely as possible).
