What P0700 means for your Honda Pilot
The 2016-2018 Pilot used the troublesome ZF 9HP9 9-speed (Honda calls it the 9AT). 2019+ Pilots use a much more reliable Aisin 10-speed. The 9HP9 is the source of most P0700 codes. P0700 is the "umbrella" code that tells you the TCM has stored at least one other transmission-related fault. Always pull the full code list, not just P0700, when diagnosing.

Is It Safe to Drive Your Honda Pilot with P0700?
How to Diagnose P0700 on a Honda Pilot
- Pull the full sub-code list, not just P0700. P0700 alone tells you nothing - the TCM stores it whenever any other trans code is active. Look for codes in the P0730-P0799 range and the P0840-P0899 range.
- Check TSBs and recalls against your VIN. The ZF 9HP9 / Aisin 10-speed has documented service bulletins. A free dealer reflash resolves many P0700 cases without parts.
- Verify fluid level and condition. Wrong fluid or low fluid is the #1 cause of P0700 across nearly every modern automatic. Confirm fluid spec from the door jamb or owner's manual before any service.
- Inspect the pan magnet for ferrous debris. Heavy metallic shavings mean internal wear; a fluid service alone will not save the transmission. Plan for a reman if you see significant debris.
Common Questions About P0700 on the Honda Pilot
Did Honda buy back any 2016-2018 Pilot for the 9-speed issue?+
Some owners have successfully invoked state lemon laws and gotten buy-backs or extended warranties. Honda has also offered goodwill repairs. Document everything and escalate to Honda Corporate Customer Affairs if a dealer is unhelpful.
Will the dealer flash fix my Pilot 9-speed shift quality?+
It helps in roughly 60-70% of cases. The 9HP9 is fundamentally a difficult unit - even the best software can not fully fix it. If the flash does not resolve harsh shifts, your next step is the mechatronic.
Is the 2019+ Pilot transmission really more reliable?+
Yes, significantly. Honda switched to a 10-speed Aisin in 2019 specifically because of the 9HP9 problems. The 10-speed has far fewer complaints. If you are shopping used, prefer 2019 and newer.
What is VCM and why does it cause trans codes?+
Variable Cylinder Management shuts down 3 cylinders on the 3.5L V6 for fuel economy. The vibration and torque dropoff can confuse the TCM into storing P0700. VCM Tuner / VCM Muzzler aftermarket devices disable VCM and often clean up the codes.
