Allison 1000 02 workhorse w22

my 2006 w22 Allison did the same thing 3000 miles after buying new was told the connecter at the module was missing insert did think that was the problem being I own a automobile shop waited 2 weeks for part when I got it back did the same thing decided to fix my self found torqe converter soliniod was reading wrong resistance droped the pan and replaced it in my driveway have never had a problem again you need to plug a scanner into obd2 plug that has workhorse solftware and read code will probably have a po700 code and another code in the 700 hundreds
