The push button on the handle of the shifter that you have to press to get it out of park on my 2003 Mustang is sticking. It's as though you try to push it while not stepping on the brake but we are stepping on the brake. We try jiggling and pushing and after a few minutes of fighting with it, it starts working fine until the next time I have to drive it somewhere. I had to replace the shift interlock cable due to it binding up and not releasing properly.
2003 Mustang gt cp, purchased from planet Ford dealership 20403 I-45 north, spring, TX 77388 (281) 719-3891 on June 28,2003. I was one happy customer until I drove my vehicle into their service department April 10,2004 when all hell broke loose about my Mustang; steering wheel vibration, rear end vibration and delayed shift in transmission. I was told to rotate my tires, balance tires, upgrade the wheel balancing and front end alignment. Along with the problems I receive three embarrassment; police escorted me off the property because I was trying to prove to both dealerships that my problem was not my tires. But, their words were that Ford has the best mechanics. I then had to drive my car to leadership Ford in dallas, TX in order for someone to provided with the proper customer service that I was denied by planet, team and russell & smith Ford in houston. Leadshiip Ford took the time to lesson to the issues and test drive the car to verified that I had a problem. They determined that vibration that I experience was caused by the transmission and the rear end, not the tires nor the front end. As a result they replaced the transmission and the rearend. I meet with planet Ford general manager - ron euren, whom apologized for the problem I had with the car. But, he followed his apology with the following words - "since you have been nothing but problems for this dealership for any addition issue you may have with your Mustang take to another dealership for service. Do not return to planet Ford otherwise you will be arrested on the spot.
