P0773: Shift Solenoid E Electrical

What P0773 usually means

P0773 is the explicit electrical page for the Shift Solenoid E family, and it is one of the best exact-match additions because scanner users often land on the word electrical and start replacing parts blindly. This code should slow the process down. Prove the E-solenoid circuit, connector, internal harness, and coil before blaming fluid condition or internal hard parts. Like the other electrical solenoid pages already on the site, P0773 is valuable because it gives the reader a clear diagnostic order instead of lumping everything into generic transmission-failure talk.

Start here before chasing parts

• Scan first: save freeze-frame and pending codes before clearing anything.
• Confirm the complaint: compare the stored code with current drivability symptoms.
• Use context: trims, live data, and related codes usually narrow the fault faster than guesswork.
• Work simplest to hardest: leaks, connectors, maintenance items, and known patterns before expensive components.

Suggested workflow

1. Capture all transmission codes and freeze-frame before clearing the fault.
2. Measure circuit integrity, power, ground, and commanded response for shift solenoid E using the correct service information.
3. Inspect connector pins, pass-throughs, and internal harness sections for corrosion, heat damage, or rubbed-through wiring.
4. If wiring checks out, test the solenoid coil and controller driver path.
5. After repair, verify the code stays gone and normal shift behavior returns.

Common mistakes

• Treating P0773 like a fluid problem first even though the code is explicitly electrical.
• Skipping shared-feed checks when several solenoid electrical codes are present together.
• Moving into mechanical teardown before the E-solenoid circuit is actually proven healthy.

Practical fix guidance

• Handle P0773 as an electrical validation job first and a hydraulic diagnosis second.
• If E-side and neighboring electrical codes appear together, inspect common feeds, grounds, and the case connector before replacing individual parts.
• Do final verification only after stable circuit readings and a normal road test both hold.
