I Have a issue with a 06 model 3000 international bus. Don't know if transmission related or Electric brake related. Bus will drive in Reverse all day but when you put in any forward gear, it will roll about 3 to 5 feet and stop very abrutly.Have taken out half the drive shaft and tried this again and the problem stops the drive shaft no matter what RPM range drive shaft will not spin at all in any forward gear. Allison electronic trans It Has a VT 365 Motor and also should have included (CE200)
Have allison Software on snap on computer. Ran diagnostic scan 1st gear checked ok 2 nd gear came up with red flag solenoid B issue won't let scan anu further.
There should be a solenoid test in the diagnostic for that. It's been so long since I done one. Basicly first check the wiring, drop the pan, check the wiring, then a mulitmeter pin test. Maybe even pull it out and clean it, inspect it.
