There are 3 adaptations required. I only had issues with the complete trans and clutch-slip. I talked about this extensively already, there is also a video. refer to Post #1. Post #25 describes what was done to address the trans teach-in situation. These were done with the trans not mounted to the engine as I had described in Post#15 in the last paragraph, it worked perfectly and allowed me to inspect the values in my other SMG controller also.I was asking in what adaptation it failed, that may indicate something at that point.
I don't understand what you are talking about. I have not found a way to replace the clutch fork without removing the trans. Removing the gear strip sensor is technically doable with the trans still mounted and it tilted back, but I'm not a midget, and when you open up the hydraulics it's essential to be clean when sealing things up. Removing and replacing the actuator block is not possible without dropping the trans. I mentioned in post 15, the plan and post 25 the result. I don't know what you are talking about regarding different harness on the block, except possibly the gear strip sensor.Was not not necessary to drop the box You did a good experiment by installing different harness on the block but it failed but that may not was the reason of failure, the step that failed may reveal more info about the cause.
No not really, they are not merely values within a tolerance, adaptations are really calibration values. 4F66 and 4F67 are codes that are set when a new adaption is attempted and completed unsuccessfully. Upon the successful adaption the new values are displayed and written to memory. ISTA shows what the prior values were, in my case when trans adapt was successful, it showed the prior values to be all zero, indicating an uninitialized state.adaptation is very important factor that means your system is within the tolerances stored in the memory and that tolerances what make the ECU throw fault codes.
If both of those test out without problem, it is possible that there is a problem in the actuator block. You can monitor the sensors in INPA via the "read status" screen and look at the shift rod positions. If there is an error on the shift rod sensor strip, it may indicate erratic behavior here. This is not unusual as the insulation on these strips tends to decay and rot away.
The shop isn't in left field wanting to pull the actuator block off the top of the transmission to inspect the mating of the shift pistons to the shift rod carriers, but there are a few steps they can look at first without dropping the transmission.
