I have a '96 E350, 7.5L, E40D that is a transplant from a '97 E350. Approx 55,000 original miles on this tranny. Regular fluid changes. Use is my work truck, 80% in-town speeds and 20% highway speeds. I have been having subtle intermittent shifting issues. I unplgged the solenoid block connector on the passenger side of the tranny to clean it. Inspection of the bulkhead connector showed 5 of the 9 pins had corroded off, and remained embedded in the harness side of the connector. It must be changed. Do I need to replace the entire solenoid block, or can I remove and replace just the connector? I searched for a write-up on this repair, but could not find one. A link to the procedure would alleviate some anxiety on forging new territory. Thank you. Kirt

 

You must replace the solenoid block. The connector is molded with the block, it is not a separate piece.

 

Thank you, Mark. Anything special about changing the block that I should know? (Like other parts falling out when the block is removed) Kirt

 

Nope. It's straightforward. Sometimes the connector is really hard to get out of the case.

 

Thank you for all your help, on this forum and another. Your knowledge and willingness to help hacks like me has really helped keep my trucks on the road. Kkrt

 

Good morning. As you said, Mark, the solenoid block replacement was a piece of cake. My work truck is back to shifting like new. Thank you again for coaching me. I am so thankful for this cite. Without it, I would be spending way more on vehicle repairs and I would not be enjoying my dentsides, like I do. Kirt
