Your transmission came off the production line on 16 October 2002 so it had all the final development fixes, including the stiffened A-clutch drum. Iíve just been looking through your post from the beginning. Although I realise this isnít the main issue under discussion here, from the photo in your first post that looks like a 328 valve body assembly that you fitted as a replacement? Can you double check the number etched into the lower rear valve block on your original photograph as the resolution of the posted photo isnít quite high enough for me to be sure? If it is a 328 then this is the wrong unit for a 4.6is, which has to have a 353 unit because the B-clutch and E-clutch valves are different. Your upper valve block should have Ď075í etched/stamped on it, which is a further check.

So do you think I selected the wrong part (see updated first post) ? I was just trying to follow the instructions I've seen on threads posted here to select the valve body with the correct amount of coloured solenoids. Furthermore, many many times I have seen other users recommend the revmax rebuilt units. On the ordering page the part claimed to be compatible with 4.4 and 4.8 so I just assumed the 4.6 was compatible.

Compatible Car Model : 540I 740I 740IL X5 XJ8 XK8
Engine : 4.0L 4.4L 4.8L
Did the supplier sent me the wrong valve body. Where would I go from here ? What would explain that the rebuilt valve body shifted through all the gears on an initial test drive.

The 328 valve body assembly is an old spec. with the 9mm main pressure valve land width, the old design of EDS5 damper, the earlier check valve springs, earlier restrictor orifice one-way valves, etc. The 4.8L theyíre referencing is the 035 model of the 5HP24 which was used in the E39 B10/E52 Z8. They only made a total of 770 of these transmissions, but this model also used the 353 valve body assembly (the same as the E53 4.6is) so it is not the same as the 4.4L assembly. Iím not suggesting that this is the cause of your current problem, just pointing out that your valve body assembly replacement is the wrong one.

Back to the electrical/electronic stuff. The wiring diagram that you referenced earlier :

I actually produced for the L322 Range Rover. Obviously the E53 and L322 are close sisters but were you able to check that the pin connections are identical for the E53 from the newTIS info, because I havenít checked this?

UPdates: Requested a return for the replacement valve body as it's the wrong one, As per RRPhil.

To do:
remove the new valve body from the transmission, and install my old unit.
buy and install a genuine bmw transmission filter, as per RRPhil claiming often times secondary brands can have the filter element sucked inside.
measure all the solenoid and pressure regulator resistances in my existing valve body for reference.

determine the canbus waveform and voltage specifications for my vehicle. start to troubleshoot the circuit and remove modules connected to the canbus until the poor signal / issue can be identified.

update the graphic in the previous post with correct pin numbers and resistances for resistance tests.
