@Giacomo congratulations!

Ps. I should watch YouTube on how to prepare for installing a phone holder before drive 😄😄 it should not be very close to the eyepiece!!!, @Frederic, when going next time?

Passenger after deflating 🙂

The fog was beautiful, not too strong, where I was driving Hope everyone is safe, thanks again for amazing night

@Imran Asghar boom shaka maka 😅

@CY Bong it was a pleasure to meet you! Hope our paths cross more!

On my Expedition Timberline, the cooling is simpler than your JL. There is no separate air-cooled transmission cooler from the factory. The gearbox uses a heat exchanger that runs engine coolant against the transmission fluid. This means the ATF basically cannot get colder than the coolant. When the engine gets hot, the gearbox has nowhere to dump its heat. I log data with CarScanner and an OBDLink adapter: ATF temp, coolant, intake air, RPM and boost. I drove up Jebel Akhdar to the Saiq plateau and back. The trip had three very different parts: Going up (about 38 min, around 38°C at the bottom): For the whole climb I kept the gearbox locked in 3rd gear manually. I did not let it shift higher. This held the revs around 2500-3000 and stopped the gearbox from jumping between 3-4-5 all the time on the corners. Less shifting under load means less heat, and the car felt more stable. With this, ATF went from 92°C up to 110°C, and coolant reached 108°C. You can see the heat exchanger limit here — ATF and coolant climbed together and stayed only about 2 degrees apart. Intake air went from 39 to 61°C. No knock, everything normal. On the plateau (about 26 min, around 2000m): This was the easy part. ATF stayed between 77 and 99°C. The air up there is cool, so intake dropped to 36-54°C. The car was relaxed. Going down (first 8 min): ATF went back up to 106°C, even with engine braking. The interesting part: knock retard jumped to almost 7°. This was on a closed throttle while braking with the engine, going downhill. High revs, hot engine, thin air at altitude. The computer pulled timing to protect itself. I only use Super 98, so it is not the fuel. Just something I did not expect to see going downhill. What I think is normal, and what worries me: ATF below 105°C is fine. 105-110 I watch it. Above 115 I would stop and let it cool. Coolant near 100°C in summer is normal for this car. The radiator is working hard but it is okay. After a hard climb, the ATF temp can keep rising for a few minutes after you stop. So I let it idle 5 minutes before turning off. One question for you all: my "Fan Speed Desired" reading stayed at 0% the whole time, even at 110°C. I am not sure if CarScanner is reading the wrong value for the Ford fan, or if something is wrong. If anyone knows the correct fan PID for the 3.5 EcoBoost, please tell me. The biggest help was holding a gear manually on the long climb. Much less shifting and the car feels more stable. PS. Car was loaded (Me, wife and 2 kids, and full trunk of different staff)

Let me pull data from my car scanner from last week when I was on Jebel Shams and Akhdar

oh! might be I also join, but I'll definetely will need a lift route for my Celestron 9.25"

@khurramm Islam is unable to post, maybe because the subscription has finished. He remembers it's Profender, but I remember the label Bilstein. Give me some time, and I'll try to take a photo and send it to you

@Islam Soliman I think he wants to know which shocks exactly you have installed on the GMC

@khurramm hi! It's Bilsteins, but which model - don't know, thinking 5100, but let's wait for the reply of Islam

@Jason M or might be some little puncture, some pin maybe, anyway worth checking in tire shop

PS. @ChrisW , you took A versions of Kings, adjustable or without adjustments?

I had the same with changing the bumper 😄 Funny thing, once I installed roof rack, it little bit balanced bumper, and even last time on Big Red it was not that much nose diping! but still I want Kings 😆 maybe @ChrisW will recommend some shop for it )))
