Noise in a Fordomatic transmission when in park gear can be caused by several factors, including worn or damaged internal components, such as bearings or gears. Additionally, issues with the parking pawl mechanism, which locks the transmission in place, may lead to clattering or grinding sounds if it is not engaging properly. Low Transmission Fluid levels or contamination can also contribute to noise. It's advisable to have the transmission inspected by a professional to diagnose and address the specific issue.
maybe it is a problem with you 1st gear being warped because when ur stopped u are in 1st gear but park is a different gear
U-joint is the first place to look. Second would be worn ring and pinion gear.
horses make neighing sounds
It being in neutral or park.
A vacuum leak (Brake booster).
What kind of noise? It could just be the park lock solenoid clicking when it releases to engage drive, this wouldn't come from the gearbox though, it would be from the gear selector unit under the centre console.
If your talking about when your in park that click is releasing the transmission so you can shift into gear
The engine also jumps when changing to Neutral and Drive. Should I have transmission fluid change? A/C was not on.
Your probably letting your transmission roll forward or backwards after you put it into park. This puts pressure on the transmission where it stops and it "pops" out of park for this reason, making the loud noise. Apply the E-Brake after putting it into park but before you let off the regular break, it wontcontinue to roll.
Sounds like it could be a bad wheel bearing
transmission shift bolt loose try pushing gear shifter all the way back to park
There's a few reasons: When a automatic transmission vehicle is turned on, the small but the seemingly small burst of energy it takes to start the car by means of combustion, it may rock the motor mounts and cause maybe a moving.. or bumping sorta sound. When you move the gear lever in any position, the energy from where in neutral, the torque converter, which keeps the engine running while in a gear, or switching to another selection of gears, has to mesh with the flywheel of the engine so that you can press down on the accelerator pedal/ brakes and causes the noise of the motor mounts absorbing that energy. However, the noise shouldn't be a very loud noise, if it seems loud it could be either a motor mount(s) going bad and needing replaced, to possible transmission problems.
