F Pace Gearbox Failures Point to Control Module Issues

As someone with some hands-on experience with Jaguar transmissions, I dealt with very similar symptoms on my 2020 F Type diesel last year. The transmission control issues you describe match what I encountered, erratic shifting, unresponsive paddles, and the automatic gearbox going into limp mode. After the transmission diagnosis at my regular workshop, they confirmed a defective control unit was causing the communication problems between the car computer and transmission. The automotive ECU was receiving incorrect signals, leading to those grinding sounds and rough shifts you mentioned. The complete repair involved: Full diagnostic scan, Transmission control module replacement, Software calibration, Test drives to confirm proper function Total cost came to 1000€, but it completely resolved the issues. The automatic gearbox has worked flawlessly since. To provide more specific advice for your case, could you share: Current mileage, When the problems first started, Any recent service history, Specific error codes showing up, Whether problems occur more in cold or warm conditions This information would help determine if your F Pace is experiencing the same control unit failure I encountered.

Thanks for the detailed reply and yes, my mileage is 122694 KM. After reading through your experience, it seems our transmission diagnosis scenarios are quite similar. The automatic gearbox problems started showing up right after my last scheduled service three weeks ago. The workshop initially cleared the fault codes but the gearbox issues returned within days. The car computer shows error code P0705 which relates to the transmission range sensor circuit. The problems definitely get worse when the engine is cold, particularly during morning starts. The automotive ECU seems most unstable during the first 10 minutes of driving. After that, the transmission behaves somewhat better, though still not normal. I will book another workshop visit and request they specifically check the control module based on your feedback. A 1000€ repair would actually be acceptable if it permanently fixes these transmission control issues. Much better than risking more severe damage to the automatic gearbox.

Thanks for those additional details, your symptoms continue to mirror what I experienced, especially the cold-start transmission control issues and that specific P0705 error code. The timing of your gearbox problems starting after the service is noteworthy. In my case, the automatic gearbox issues also intensified after routine maintenance. The workshop later explained that sometimes these services can trigger latent transmission control unit problems to surface. My repair experience suggests your automotive ECU is likely misinterpreting signals from the transmission range sensor, just as mine did. The cold-start behavior you described is a classic sign of a failing transmission control module, the electronics are most unstable before reaching operating temperature. Quick word of caution: while my 1000€ repair worked out well, make sure your workshop does a complete transmission diagnosis first. They should verify the control unit is truly the culprit before replacement, as other gearbox issues can show similar symptoms. Keep us updated on what your workshop finds. It would be helpful for other F Pace owners facing similar transmission problems to know the outcome.

Thanks for the insights. Just wanted to close this thread with a quick update on my F Pace transmission repair situation. The workshop completed their transmission diagnosis yesterday and confirmed the control module was indeed faulty. The electronic issues matched exactly what was described, they found corrupted signals between the automotive ECU and transmission components. Total repair cost came to 1150€ including: New transmission control module, Programming and calibration, Full system diagnostic scan, Extended test drive verification The automatic gearbox now shifts perfectly, with no more grinding or slipping. Cold starts are completely normal and the paddle shifters work as intended. The P0705 error code has not returned. For anyone searching the forums later with similar gearbox issues, having the workshop focus directly on the control module saved time and prevented unnecessary transmission repair work. The systematic diagnostic approach made a big difference in getting to the root cause quickly. Thanks again for pointing me in the right direction with this transmission control problem.
