Transmission problem V8 Four Wheel Drive Automatic 65.000 miles Hi, I have a problem with my X5 4.4 2002 Auto Transmission. After driving for a while, such as half hour, the transmission does not shift properly anymore. Usual operation at startup is quite good and not any sign or jerkyness or error message. The first 10 to 15 minutes the transmission works fine, also it does not feel jerky in any way. Shifting is also still carried out smooth, however the shifting point is much too high, I need to rev the engine to about 3 to 4K before shifting occurs. Usually it would shift much sooner, around 2K to 2.5K I believe? It definitely feels wrong.

It means I drive on the highway only in 2nd or 3rd gear at very high revs. Need to push the pedal hard to force gear shift at v. High revs, up to 5K sometimes. Shifting down would also occur too soon when coming from higher gears, leading to a jerky braking at traffic lights as the revs are too high on the downshift. But this issue is more irregular whereas shifting up becomes a constant problem after running the car for a while.

I also tried to change gears in manual mode. When I want to shift into i.E. 3rd gear at revs below 4K it would not engage the gear and the display would show a drop back to 2nd after 3rd was shown on the panel for a brief moment. I felt that 2nd gear was still at work. Same applies to shift gear 1to 2, 3 to 4, etc. I can only do the manual mode shift at high revs (min 3.5 to 4K) Have had the problem checked and the transmission cleaned, oil cooler replaced, filter replaced etc.

Cost a lot of money but problem re-occurred immediately on my way home after I picked up the car and drove for over 30 mins. What could be the problem here? Computer did not produce any error messages either. Arduino Serial Buffer Clear here. Could it be a rev sensor, or any other component not directly in the transmission? Do I need to get the transmission disassembled?

It started at 65K miles and I drove it to the repair shop immediately. There it was in for a few days and they changed a few things on the transmission such as coolant, filter, oil cooler. Also the diagnosis didn't show any error message. When I picked it up, after driving for 30 or so minutes without any problems, the same thing happened again with the problems described and now I am waiting what to do and if I should let them dismantle the transmission or could it be a software issue (would be strange though that shifting always works fine in the first 15 minutes?) Please please help, had already too many problems with this car and spent a ton of money on repairs too:(. As the transmission was not functioning properly, esp after being warmed up, the workshop tried to replace items which did not require to open up the transmission. Also they have not found any faults in the diagnosis.

I guess this was not necessary? I did some more driving yesterday and found that shifting occurs too late, for any gear. It should shift much quicker up into third, but now it shifts so late the fan blows quite loud and I hardly hear the engine rumble any longer. Could it still be a software or sensor issue or would it be transmission parts? The method if GT1 diagnosis and it did not show any fault. So this would rule out any sensor issue?

However I can confirm that, at high temp when the car is warm, the tranmission misses to shift at the right RPM, i.E. Shifting still, but too late. Downshifting can also be too early but this problem is less pronounced. Importantly, before this problem occured, I had a leak in my cooling system and the engine was running on low water for some time until smoke came out and the car was towed. Could have been overheated slightly, but BMW confirmed no damage was done to engine. However the transmission could have been damaged by this?

Where could the problem be, as the diagnosis does not show faults at all. The problem with the transmission first occurerd after I had a leak cooling system fixed, but it was fixed at this auth. BMW shop so I assumed it was all fine, hoses, water pump, thermostat, etc were all replaced and everything checked. The first time the transmission misssed to shift gears occured I was stuck in traffic jam and driving over 1 hr before the transmission started to act funny and not shift up properly, generally just felt 'wrong'. Driving on highway didnt make it better, at too low gears.
