U1058 — SCP (J1850) Invalid or Missing Data for Transmission / Transaxle / PRNDL

U1058 — SCP (J1850) Invalid or Missing Data for Transmission / Transaxle / PRNDL. A fault in the automatic transmission control. Short, gentle driving to a shop is usually possible. Typical causes: faulty transmission speed sensor, internal mechanical wear (clutches, torque converter), valve body wear.

Is it safe to drive?

Drive with caution Drive only if the transmission still shifts predictably, and avoid highway speeds. Driving with slipping or limp mode accelerates internal wear — every kilometre can add to the final repair bill.

How to diagnose with an OBD scanner

  1. Read the code and freeze frame Connect an OBD2 scanner, confirm U1058 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
  2. Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many U0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
  3. Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the automatic transmission control for damage, corrosion, chafing or poor contact.
  4. Subsystem check Check transmission fluid level and condition — dark, burnt fluid points to internal wear.
  5. Subsystem check Read transmission-specific codes and live data (solenoid states, input/output speed) with a capable scanner.
  6. Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm U1058 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for U1058 (parts and labor, USD, independent shop rates): Replace a shift solenoid: $300–$800; Transmission rebuild or replacement: $2,500–$5,500; Transmission fluid service: $150–$350; Valve body repair or replacement: $700–$1,500. Overall, fixing U1058 usually costs between $150 and $5,500. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.

Common questions

Is it safe to drive with U1058?

Drive only if the transmission still shifts predictably, and avoid highway speeds. Driving with slipping or limp mode accelerates internal wear — every kilometre can add to the final repair bill.

Will U1058 clear itself?

Sometimes U1058 clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.

What does OBD2 code U1058 mean?

U1058 — SCP (J1850) Invalid or Missing Data for Transmission / Transaxle / PRNDL. A fault in the automatic transmission control. Short, gentle driving to a shop is usually possible. Typical causes: faulty transmission speed sensor, internal mechanical wear (clutches, torque converter), valve body wear.

What are the symptoms of U1058?

Drivers most often notice: harsh or delayed shifting, Check Engine or transmission warning light on, slipping between gears, no movement in severe cases.

How much does it cost to fix U1058?

Replace a shift solenoid — $300–$800; Transmission rebuild or replacement — $2,500–$5,500; Transmission fluid service — $150–$350; Valve body repair or replacement — $700–$1,500. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.

What does U1058 mean?

Seeing U1058 on your scanner? The control unit has caught the automatic transmission control operating outside its calibrated window. The formal description is “SCP (J1850) Invalid or Missing Data for Transmission / Transaxle / PRNDL”, and the code is grouped under vehicle network faults.

This code does not appear from a single bad reading: the module must see the fault condition repeat under defined operating conditions before it turns on the warning light. The freeze frame captured with U1058 — engine load, rpm, temperature, speed — tells you exactly when the problem occurs, so reproduce those conditions when testing.

What causes U1058?

  • internal mechanical wear (clutches, torque converter)
  • wiring or connector faults in the valve body harness
  • faulty transmission speed sensor
  • low or degraded transmission fluid
  • valve body wear

Common symptoms of U1058

  • harsh or delayed shifting
  • Check Engine or transmission warning light on
  • slipping between gears
  • no movement in severe cases
  • transmission stuck in one gear (limp mode)

How to fix U1058

Start with the cheapest and most common causes before replacing expensive parts:

  • Replace a shift solenoid — $300–$800
  • Transmission rebuild or replacement — $2,500–$5,500
  • Transmission fluid service — $150–$350

Can you drive with U1058?

Drive only if the transmission still shifts predictably, and avoid highway speeds. Driving with slipping or limp mode accelerates internal wear — every kilometre can add to the final repair bill.
