Hi Folks.
Okay, so right in the beginning I had some troubles with code 20 and 21. This was the next day I've got the gearbox in. So after some adaptation I drove about 1000kms.
So a week ago code 20 and 21 showed up again, mostly after pulling with some torque. Got it one time, 2 times and after that more often.
So after a couple of times adaptation the problem seems to be fixed. (Don't know for how long)
Am I do something wrong with adaptation? (Picture)
Adaptation numbers don't say anything to be..

Re: Adaptation
Those errors are for both speed sensors and nothing to do with adaption. The errors are due to the TCU not getting a signal back from the speed sensors. Create a log file and look at your input and output speed and see if it's dropping out.

Re: Adaptation
Clear. I will do that.
I think it's strange both of the codes are showing up.
Logically if there is one sensor that keep throwing codes i would say its only showing 20, OR 21.
Speedometer keeps reading when it drops out of gear and codes shows up, so I think the longer one (pump side) would be good. This is the sender (correct me if I'm wrong)
Both codes showing up everytime. Gives me headaches right now. Maybe because it's my first 8hp build and this one isn't going easy..
When I turning off the ignition, and start all over it drives again by some time.. I can drive some km's when I drive like a old lady, but when I hit the throttle for once it's throwing codes right away.
However, I will check my parameters.

Take a look at the log and see if your getting a negative slipt value with positive tq during your shifts/decel. Other than that make sure the crimps are good on the TurboLamik controller (if you made the harness). The errors are for a disconnected sensor so the points of connection are limited as you know. Solder connections at the PCB in the trans causes everyone headaches.
