it’s very strange as it only ever does it when I’m hard on the throttle it’s Asif it can’t decide what gear to be in sort of like it changes 3 times then brings m+s on. I’ve just done another stall test it revs to 3000rpm.Hi the LR description of that code is
"P0721(21)* Downshift safety monitor prevented downshift which would have caused engine overspeed" corroborated with the stall test result above 2800rpm seems very like a clutch slip.... IMO that's what it is, not electrical at all
