Ishift Problems

Thank you for the quick reply

 

Is the ribbon harness inside the transmission or outside?

 

I'm at a small fleet. Experience with everything but Volvo and Mack. Truck wont calibrate a new clutch. It doesnt see the engine speed. Is this sent from the engine to the trans, or measured at the trans? Tach works...

 

We do have PTT, and I'm still learning it. I should mention that PTT says that it does not see the ECU or the Aftertreatment, however engine runs fine and there are no aftertreatment warnings. p105254 and p106154 are the only trans codes, and the ecu has a psid230 (improper shutdown).

 

did you find the problem here?

 

Where is the switch on the batteries? You talking about a low voltage disconnect? I don't think mine has one, unless its the little "LVD" light or sign in the sleeper that you have to push a bunch of buttons to get to. I don't think mine has ever worked, if it's even there.
