I have a concern with the auto in my car. I've taken it to the dealer a couple of time, and they tell its normal on these cars. What happens is when you are slowing down almost to a stop and the trans down shifts from second to first you can feel the shift like thump. If you accelerate at the point of the shift there is a void until it completes the shift.
Has anyone with an auto felt this, and if so has the dealer found a solution.

I bought an intake an tuner form steeda, and install the set this weekend thinking the programming of the computer would fix it, and the thump noise is actually worse. Now it makes a loud clunk noise, and it doesnt do it all of the time.

Could this be the torque converter shaft or maybe a part in the trans thats not working correctly.

My suggestion would be to put the stock parts on the car and return it to the dealer. Get them to take you on a test drive with another automatic to see if it happens on the other car.

I wouldn't think it would be normal but theres no telling with these cars. I would be fearful of a loud clunk noise unless it sounds like the two piece driveshaft?

Hi slayer7391,

You know, d98gt had a great idea of test driving a Mustang with a similar setup to determine if your concern occurs on both vehicles. Please PM me with your VIN, contact information, mileage, and servicing dealer information if you would like additional assistance.

Not sure what happened, but I did my first oil change at 3,000 miles and took the car for a spin, and the trans now shifts great when downshifting. I really glad this went away, as I'm a very picky driver, and this would have buged the **** out of me.
