Save the evidence first
- TCM codes, not just the engine-module request
- Shift behavior, temperature message and fluid-leak observations
- Freeze frame before clearing
Safe owner checks
- Stop if the display says stop safely or motion/control is unreliable.
- Note whether the issue began cold, hot or while towing.
Questions for a qualified technician
- Can the tool read the exact TCM and its enhanced data?
- Are power/wiring/sensor/software or internal mechanical causes supported?
- For the Honda hybrid bulletin, does cold-start IAT1 meet the branch?
Common wrong turns
- P0700 is not proof that the transmission must be replaced.
- Do not add a generic ATF/CVT fluid without the exact specification and procedure.
Confirm the repair
- Verify shifts/temperature/code status under the OEM procedure; no generic road-test prescription.
