Hello all
I’m having major issues with the auto box on my 2012 Kuga. It’s a 62 plate 2.0 TDCi 163 Titanium Powershift. 62k on the clock, gearbox oil and filter changed by main dealer at 40k (4 years ago - So over on time, but not on mileage). Ok until Sunday but on driving back from the midlands, came off the M1 and juddered all the way home, after making one stop, then would then not go into reverse and then lurched forward in drive and flagged the “Transmission Limited Function" in the cluster/IPC. We abandoned the car by the side of the road and on retrieval next day barely got it the 2 miles home. It now won’t select gear (or even neutral) properly and stalls if you try and put it into drive. Additional to that now the engine MIL light is on and intermittently the Transmission limited function message.

I have ForScan and performed various reads, even before the MIL lamp was on the DTC’s were plenty: amongst many others - 3 for TCM:
P074D - Unable to Engage Gear 5, Code: P0797 - Pressure Control Solenoid C Stuck On, Code: P2715 - Pressure Control Solenoid D Stuck On.

Since a clear and attempt to select a gear more and more DTC’s have been flagged including a PCM issue which is continually illuminating the MIL: Code: U0415 - Invalid Data Received From ABS Control Module.
Status: - Confirmed - malfunction is confirmed

There are also various CAN/Communication DTC’s in other modules such as IPC, EPS (power steering), Door modules: RCM, RKE, such as :Code: U1900 - CAN communication bus fault, Code: U0155 - Lost Communication With The Instrument Panel Cluster Control Module etc

I also now have this TCM DTC flagged: Code: P060A - Internal Control Module Monitoring Processor Performance.

Battery tests "ok" opn a drop test and have also fully charged with a Noco charger, still the same issues present.

I have contacted a local auto transmission specialist who (even without hearing the symptoms) said: £2472 for a clutch pack and then if the ECU is faulty, then £3782 – Minimum!

So, I’m a bit stuck (and in shock at the potential cost)! Due to the various other DTC’s being raised is the TCM ECU at fault, interrupting CAN communications and is actually the gearbox clutches at fault, could it just be an ECU/sensor issue, or is it smothering else, or both. It’s also intermittently being going into a high idle at tickover. I value all your input on this greatly, not sure where to go from here? Spending that sort of money on a 10 year old car, but we were not planning on getting rid of it. We have owned the car since 2013 and it’s been a great reliable motor with only a DPF issue and a battery in the 9 years we have owned her - until now :-(

Cheers
Matt

@keithmac is our expert on the powershift gearbox. He will hopefully pick your post up and respond in thread. It would also be useful if you could note down any serial numbers or data from stickers on the box.

It's a tricky one!, at 62,000 it's not beyond reason to say the clutch pack dampers could have disintegrated to the point of making the car undrivable.

All the U codes could be from a failing instrument cluster (poor solder joints) the achiles heal of the MK1 (the cluster terminates the CanBus lines).

With the drivablility issues the gearbox does sound like it's done the normal Powershift failure.

London Automatic Transmissions are your best bet for that side of things (they will do a complete gearbox rebuild).

It may be worth having the Dash Cluster re-worked first but it does sound like the gearbox will have to cone out as well.

With the gearbox it's a mechanic failure so shouldn't be causing CanBus issues imho.

If that is just to fit a clutch pack that's far too much, a genuine clutch pack is £1200 tops. Plus if the dampers have failed you can't just fit a new clutch assy, the entire gearbox needs stripping and cleaning (to remove all the damper guide debris).

Hi Keith, thank you for your reply. Gives me a lot to think about. I may try to disconnect the TCM and rerun the DTC read, to try and verify that the CAN issues remain. It does look like a combination of issues, but it's very coincidental that they have occurred at the same time. On Saturday the car was running fine. Although that not saying that the other DTC's were not already there.
