Re: Workhorse W42 Transmission
Posted to HD/Fleet Forum on 5/12/2020

So the truck is fixed. We were able to find a used transmission connector in good shape and repair the wiring. Aparently the torque converter defaults to partial engagement when the voltage drops, which explains that symptom. Thanks for your replies, esp. Glenn, you were right on the money.
