Transmission oil overheating!
Hi guys!
I just ecu tuned my 2016 Amg GTS also I got intakes as well.
i tried to launch the car after to see the difference it give me massage that transmission oil over heated and it doesn’t let me launch the car. I tried like 7 times two or three time I did with no problem then happened again! The transmission temp was 168 or couple times was 196 , and I didn’t launch back to back!
any idea what is wrong with it? I was able to do launch control back to back before tuning with zero problems !

So those transmission temps are fine. It appears that your ECU tune is ‘corrupting’ something software wise, i.e. the ECU and TCU are no longer ‘talking’ to each other correctly. Think about it: your car is running fine; you ‘tune’ the ECU; the transmission then immediately starts throwing ‘codes’; so what do you think is causing the problem?

I went to the dealer and I left car with them. The technician is my friend and he knows I have tuned ecu! He is looking at it today, I hope I can get an answer!

The Dealer technician is my friend, he said he need to update the transmission computer but he can not do it without updating the ecu. If he connects the computer to ecu automatically will copy ecu and send it to Germany. They will find out you have tuned ecu and your warranty will void. You need to send it back to your tuner to copy the original file, then I can fix the issues and you retune it again!!!

They respond me quickly, hope they help me to solve the issue and retune ecu for me again. I went with HDtuning because I saw so many good reviews in this forum about them and so far I don’t have any issue with them!

So after tuner flashed my Ecu to stock, I did try launch control 23 times back to back without any issues. I belive the tune had issue. I will go to the tuner shop on Wednesday to see what they can do about it!!!

This is the issue with small many tuning shops. They work into the ECU through software reverser engineering and disassembly, a very limiting activity in terms of understanding what is going on, peek and poke around, but cannot do complete work. Go with the well established names (and still be cautious). They often paid big bucks for the source code and really understand what is possible.

I just want to give you guys an update, the car had issue with the transmission coolant pomp and need transmission control unit software updates! After I got my ECU to stock Mercedes fixed that for me. I sent back my ECU to HDTUNING, they tuned it again with no problems. I ran 1/4 mile 11.1 with 91 octane. 0 to 125mph (200km) 10.3 s ...
the car is changed to different animal.
I had really good experience with HDTUNING. They help me to solve the problems! I Highly recommend them. They answer text me hundred times right away Matt and Josh are amazing to work with !

Mercedes told me the transmission coolant pomp they’ve ordered has different part number and it’s stronger, also the software update for transmission was significant, they’ve changed so many parameters regarding temperature. I think they knew 2016 model had issue that’s why they’ve made so many changes!
