2005 Honda CR-V RD7 Not Moving: Transmission Diagnosis & Repair Case Study in Dhaka

The Customer Complaint

A 2005 Honda CR-V (RD7) recently arrived at MRB Auto Solution with a serious drivability complaint: the engine was running, but the vehicle would not move under its own power in either Drive or Reverse.

A symptom like this can have several possible causes, including transmission hydraulic problems, electronic control faults, torque-converter issues, internal clutch or geartrain problems, or other drivetrain-related faults. That is why we diagnose before replacing parts.

Step 1 — Full-System Diagnostic Scan

We connected our diagnostic equipment through the vehicle’s diagnostic connector and performed a system scan. The scan reported faults in several modules:

The presence of multiple fault codes does not mean that every code represents a separate root cause. Some codes can be secondary or related to the primary drivetrain problem.

Step 2 — Understanding the Transmission Codes

P0700 — A/T System Malfunction

P0700 is essentially a transmission-related malfunction request to the engine control system. It does not identify the failed transmission component by itself; the TCM-specific codes provide the additional diagnostic evidence.

P0722 — Output Shaft Speed Signal

The TCM reported P0722, indicating that the expected output-shaft speed signal was not being received correctly. This is important because output-speed information is used by the transmission control system to determine what the transmission is doing. The code alone does not prove that the output shaft itself is mechanically broken, so the sensor, circuit and mechanical operation all need to be considered.

P0780 — Shift Malfunction

P0780 indicates that the transmission control system detected a shift-related malfunction. Possible causes can include hydraulic, electrical, control or mechanical problems.

P1734 — Shift Malfunction F

P1734 adds another transmission shift-related fault to the diagnostic picture. When considered together with the physical symptom — no movement in both Drive and Reverse — the transmission requires further mechanical investigation.

P0848 — 3rd Pressure Switch Circuit High

P0848 points toward a problem involving the 3rd clutch transmission-fluid pressure switch circuit. This code should not automatically be interpreted as proof of a failed clutch or insufficient hydraulic pressure. The switch, wiring, connector, control system and actual transmission operation need to be evaluated.

Step 3 — Other Diagnostic Findings

P0171 — System Too Lean

P0171 was also present in the engine-control system. This indicates a separate engine-side mixture problem that should be diagnosed and repaired independently.

SRS 11-10

The SRS module reported an open circuit related to the left-front airbag inflator. This is not a transmission fault, but it is a safety-related issue that should be addressed separately.

ABS/VSA 83-01

An ECM/PCM relationship fault was also recorded by the ABS/TCS/VSA system. Because vehicle control modules communicate with each other, drivetrain or communication faults can sometimes result in additional related codes. These should be rescanned after the primary repair to determine which faults remain.

Step 4 — Why We Decided to Remove the Powertrain

At this point, replacing a pressure switch or solenoid without further investigation would have been guesswork.

The combination of no movement in Drive, no movement in Reverse, transmission shift-related DTCs, abnormal output-speed signal information and a pressure-switch circuit fault justified taking the next diagnostic step.

The transmission needed to be physically inspected.

We proceeded with powertrain removal so the automatic transmission could be separated, opened and mechanically inspected. The objective was to determine whether the problem was electrical, hydraulic, mechanical — or a combination of these.

Step 5 — Powertrain Removal

On 2 November 2026, our team began removing the CR-V’s powertrain at our Vatara workshop. The engine and transmission assembly was supported and removed so the automatic transmission could be separated for inspection.

Workshop update: The transmission is being prepared for teardown and detailed inspection.

What We Will Inspect

• Clutch-pack wear or damage
• Burnt or contaminated friction material
• Bearing condition
• Gear and shaft condition
• Hydraulic passages
• Transmission pump condition
• Pressure-switch operation
• Solenoid condition
• Seals and gaskets
• Torque-converter condition
• Abnormal metal debris or contamination

Where required, components will be measured against applicable service specifications rather than judged by appearance alone.

The Diagnosis Isn’t Finished Until the Mechanical Evidence Is Confirmed

A scanner can tell us what the control system detected. It cannot always tell us why the mechanical system failed.

That is why we are documenting this CR-V case in stages:

Scan → Analyse → Remove → Teardown → Measure → Repair → Reassemble → Road Test → Final Scan

Once the transmission is opened, the internal findings will determine the final repair scope. We will update this case study with the actual mechanical findings and photographs from the teardown.

What Should Honda CR-V Owners Do If Their Vehicle Stops Moving?

• Stop the vehicle safely.
• Check whether both Drive and Reverse are affected.
• Avoid repeatedly revving the engine to force engagement.
• Have the transmission system scanned.
• Record the exact DTCs.
• Have the transmission inspected before replacing expensive components.

A transmission fault code does not automatically mean that the entire gearbox needs replacement. Likewise, a single sensor or solenoid code does not automatically mean that replacing that component will solve a complete loss of movement.

Honda CR-V Transmission Repair in Dhaka

At MRB Auto Solution, we handle diagnostic and repair work across Japanese, European, Korean and other vehicle platforms.

• Computer diagnostic scanning
• Transmission fault-code analysis
• Electrical and wiring checks
• Pressure-related diagnosis
• Solenoid and sensor testing
• Automatic transmission removal
• Transmission teardown
• Component inspection
• Transmission rebuilding
• ATF service
• Adaptation / relearning where applicable
• Post-repair diagnostic scanning
• Road testing

The exact repair procedure depends on what the diagnostic and mechanical inspection actually finds.

Final Repair & Road-Test Update

This section will be updated after the transmission teardown is completed.

We will document the internal findings, failed or damaged components, rebuild process, reinstallation, final diagnostic scan and road-test results so the final case study reflects the confirmed failure rather than assumptions made before teardown.

Need Your Honda CR-V Diagnosed?

If your vehicle doesn’t move in Drive, doesn’t move in Reverse, has a flashing D light, transmission warning lights, harsh or delayed shifting, or shows P0700, P0722, P0780, P0848 or related transmission codes, don’t replace expensive parts based on a code alone.

Send us a photo or video of the symptoms or your diagnostic report on WhatsApp. Our team can review the information and advise you on the appropriate next diagnostic step.
