I've got an odd problem with my '03 Disco 2 that's slightly worrying. The issue has occurred 4-5 times, only one time per trip. The issue is also not biased towards any particular driving scenario. It's completely random. While driving, a loud 'clunk' can be heard, and the whole truck jerks as if the transmission slips into neutral. Simultaneously, the engine light flashes on, then off. It only happens for a second than continues on normally... well it did until today. After the clunk occurred, the transmission slipped into rescue mode. The "S" and "M" lights, the "D" on LCD screen, and the gear indicator light on the console began to flash. If I recall correctly, the transmission defaults to 3rd gear in this rescue mode. Anyway, what could be going wrong here? Is this a wiring/electrical issue, or is the transmission giving out. OR is the transmission just low on fluid. Thanks in advance!
