| Message: | P0301 is misfire on cylinder 1 P0308 is misfire on cylinder 8 P0111 is intake air sensor range performance P1582 is flight recorder data stored P1260 is security problem (I thought) P1316 emissions level exceeded due to misfire I drive a Audi A8 W12 with the same 6HP26 gearbox fitted. The rollout shifts are also poor on this car, also the BMW 745i (latest model) with the same gearbox exibited the same problem. It's an inherent imperfection of the gearbox hardware, and on the Jaguar it's far less anoying as on the other cars (as it does have modified harware compared to the Audi and BMW to cope with it better). The problem is that under certain conditions the it times the shifts wrong, causing some torque transmittal through the gearbox while slowing down. Under certain circumstances this can be felt as a lurch. I haven't driven the latest software on the Jag's so I cannot comment on this. Judging by your error codes, it might not be the gearbox at all, but a problem with your engine, causing the EMS to calculate the your incorrectly and sending this incorrect torque signal to the gearbox, causing the TCM to get confused and bad shifts as a result of that. The intake air temperature sensor (IAT) error for instance could cause something along those lines. I know it does sound not very convincing as you have this problem for such a long time.
