I've got a 2015 Grand Cherokee with the 8-speed that's been doing this weird hard downshift from 3rd to 2nd only when the engine is fully warmed up. I've taken it to two different general transmission shops in Abu Dhabi and both basically said "we can't replicate it" or "maybe a fluid change will help" which didn't do anything. I'm starting to think these places just don't have the right scanners or experience to read the adaptive shift logic properly. Someone told me that a real Jeep Repair Specialist Musaffah would have the manufacturer-level diagnostic tools to actually see what the transmission control module is doing in real time, not just pull generic codes. I'm genuinely curious how their approach is different. Do they reprogram the shift points? Is there a known software update for this issue? I'm not looking for a cheap fix, I just want to understand what a specialist can do that a regular shop can't before I spend more money on guesses. If anyone knows the technical side of this, I'd love to hear it.
