Once you start a post about a component or system, just stick to keeping your concerns within that post. 🙂
This is where getting a good scanner that reads live data would really pay off. Throwing parts at a car is never a good idea. Other possibility's is the conductor plate inside the transmission are known to go bad. The electrical connector on the front right side of the transmission can get ATF within those pins and cause weird electrical issues. Also that dual linear switch on the right side of the J gate are known to needing a good cleaning and adjustment. Again, these are just some examples that can go wrong on the Mercedes transmission. We really need live data to accurately and quickly provide you with answers.

Thank you and I apologize i am a bit scattered with this myself the car a 2001 jaguar xjr 4.0 supercharged i read some live data on it when i initially purchased the car and everything was normal (within spec) i brought the car to a local shop to get the shifter adjustment accurate and now i am told the lights illuminated and they could clear the codes so thats a plus! And since the codes are clearable now it may be fixed However understanding the conductor plate goes bad yesterday i ordered a Daimler replacement conductor plate (that was not easy to get under $150) scored it for $105 and a new cable is on the way as well i do know most people dont like throwing parts at cars but in the end id rather buy new parts then use the old worn ones granted there good quality the parts i replace wont go bad and if they do i have warranties if i had the money id replace everything working or not brand new parts tend not to die the next day or in change of season so I definitely like throwing random parts at it till its fixed in fact i encourage it that being said heres the new
-Shifter assembly (old one was very worn out i got a nearly new one).
-shifter cable (old one was very difficult to get to move freely inside its casing)
-conductor plate (working or not when not if it stops working ill have it at the ready) if it goes strong till i die then great i was prepared.
common issues are sorted for now but i wont know until the shop is finished with the cable installation mine broke at the hole end (dont ask things happen 😉
Codes are
pending: P0705 transmission range sensor circuit(PRNDL input)
stored: P0705 transmission range sensor circuit(PRNDL input)
P1638 can link ecm/instm circuit/network

1998 Jaguar xjr 4.0 supercharged (p0715) turbine/input shaft speed sensor circuit
I just changed my conductor plate as well as my connector from gearbox to selector and new updated bushing for connector still having the exact same issue after replacement I hadn’t even turned the engine over and the code was already their

is their any way you could FaceTime me and walk me thru this please ? I’m having the exact same issue 98 jag xjr 4.0 supercharger (p0715) today I replaced the conductor place and new plug and plug bushing since I seen atf in the plug as soon as I put it all together before I could even start the car the (gearbox) fault code was on and my check engine light as well obdII read p0715 instantly
