E53A Auto trans issues
 

Hi there, definately not the first person to have trans issues and more than likely not the last. If anyone can suggest where to start i.e replace trans, replace t.p.s etc that would be a big help, not owned this car long. Here is the issue. When car is cold all 4 speeds are used in the trans, once it's been running for about 5 mins it stays in 3rd gear. Most times i can change from drive to 2nd and use that to take off from intersections, on occasion that does not work and it stays in 3rd. To get reverse at anytime you have to move from Park to drive then into reverse to get the car to engage reverse. During the first 5 minutes when the trans does change it changes very hard. I suspect the trans is stuffed and needs replacement so reluctant to change filter and fluid until i am sure. Any thoughts or suggestions would be greatly appreciated. Cheers Craig
