Corolla MMT with several trans fault codes

[arousa]

Hello

My MMT 2005 corolla has been given me problems. It is jumping into neutral while driving. I scanned the car and found the following trouble codes. PO808, PO810, PO812, PO900. 

Anyone ever had these?

Was looking at a TSB for PO810 and my sedan was manufactured in UK and states ECU needs to be replaced with new design. I had this recall done years ago. So assuming something else is trigerring the faults. Clutch bad? Clutch position sensor?

Please can I refer you to this post:

 

I have reported the problem to DVSA and if applicable in your situation, even if you have had the vehicle repaired I think would make a stronger case that this issue need resolving.

I have a 2008 mmt corolla. I had same issue, I replaced clutch, gear engine and it kept doing the same. I finally replaced the transmission computer (transmission controller, TCM), and that's solved my issues. In many cases initializing the clutch and resetting the sensor position helps. Here is my reply to another post:

Codes indicate Clutch position sensor is faulty or the sensor is badly positioned. This is turn creates feedback to the ECU which manifests in a bad circuit fault. It would suggest replacing the sensor is appropriate.
