P0700 on Honda

The 10th generation Accord 2.0T uses the ZF 9HP48 9-speed automatic transmission - the same unit that caused widespread complaints in the Honda Pilot (2016-2019) and Acura TLX/MDX. Software-controlled dog clutches are incompatible with Honda's original calibration, causing violent shuddering, harsh downshifts (especially 2nd-3rd gear), hesitation accelerating from stops, and torque converter shudder between 20-65 mph. Honda issued multiple TSBs. The 10th gen 1.5T uses a different transmission (CVT or 6-speed) and does NOT share this issue. 2.0T models are exclusively affected.

Early Honda Accord CVT transmissions suffer from widespread start clutch juddering caused by a manufacturing defect. The issue causes shaking or juddering during acceleration, especially from a stop. Honda acknowledged the problem and extended the warranty to 100,000 miles or 10 years for affected VINs.

The Honda 4-speed automatic in the mid-to-late 1990s Accord is prone to slipping and outright failure, typically around/after 100,000 miles. As the internal clutch material wears, debris circulates in the fluid and clogs the shift solenoids, causing harsh or delayed shifts, flaring, and eventual loss of drive. The J30 V6 automatic (introduced in the US in 1995) is especially notorious, and the failure mode carried into the 1998-2002 V6 cars, which became one of Honda's most infamous transmissions of the era. Owners who never serviced the fluid (Honda ATF, every ~30k) fare worst.

The 2001-2005 (7th generation) Civic automatic transmission is widely documented as failing prematurely, often before 90,000 miles. Owners report harsh/abrupt shifting, the engine revving without the car moving, slipping, or no engagement in drive — typically from torque-converter failure, overheating ATF, and worn clutch packs. NHTSA complaints and HondaProblems data place 2001 as the worst year; more than half of reported failures occur under 90k miles, with about 1 in 5 before 70k. This generation falls in a gap in our current coverage (we span 1992-2000 then jump to 2006+).

P0700 on the CR-V is a generic flag the TCM raises to light the check-engine lamp; it is almost always stored alongside a more specific transmission code (commonly P0740/P0730/P0780/P0750). On the automatic CR-V the frequent underlying cause is a failing shift solenoid or lock-up solenoid valve assembly (and, on higher-mileage or fluid-neglected units, valve-body or internal wear). When it trips, the CR-V typically drops into limp mode — locked in one gear (often 2nd/3rd) — and older 4-speed/5-speed models flash the D4 indicator. This most commonly affects the earlier automatic CR-Vs (Gen2 2002-2006 and Gen3 2007-2011) whose Honda 4-/5-speed automatics are sensitive to fluid condition and solenoid wear.

The Honda Crosstour (2010-2015) has a serious transmission defect where pieces of the ball bearing from the secondary shaft can become lodged in the parking pawl, causing the transmission to slip when put into Park. This results in the vehicle rolling away unexpectedly, creating a serious safety hazard. Honda issued a recall for the transmission control module software to prevent engine stall, but the parking pawl issue persists. Symptoms include transmission slipping in Park, vehicle rolling on incline when in Park, and grinding noise when shifting.

New CVT in 3rd gen Fit (2015-2020) had significant issues, particularly 2015-2016. Hesitation, shuddering during acceleration, whining/howling noise from transmission. Honda addressed some issues with software updates. Transmission cooler addition ($80-150) reportedly prevents issues according to some owners. CRITICAL: Use ONLY Honda HF-F CVT fluid ($35-50/quart) - other fluids void warranty and cause damage. Change CVT fluid every 30,000 miles religiously.

The 2016-2022 Honda HR-V CVT (Continuously Variable Transmission) experiences shuddering, judder, hesitation, and premature belt deterioration. Symptoms include vibrations during acceleration (especially 15-35 mph), delayed engagement, and strange whining/grinding noises. Honda extended the CVT warranty to 7 years/150,000 miles for 2016-2020 models due to premature belt wear. If caught early, CVT fluid replacement can help, but severe cases require complete CVT replacement ($3,000-5,000).

The 2010-2014 Honda Insight (second generation) CVT transmission experiences judder, shuddering, knocking noise during acceleration, and complete failure. Early CVT steel belt failures were identified. When CVT fails, the green "D" indicator on dash blinks. The transmission shudders at low speeds (15-35 mph) and makes knocking noises when shifting or accelerating. Honda extended CVT warranty to 10yr/150k miles on some models. CVT replacement: $3,000-5,000.

Complete transmission failure due to faulty bearings and defective 3rd clutch components in 4-speed (1999-2001) and 5-speed (2002-2004) automatic transmissions. The 2002-2004 transmission can suddenly downshift from 5th to 2nd gear causing dangerous drivability issues. Honda recalled 1.1 million vehicles in 2004 and settled class-action lawsuit in 2006.

The ZF 9HP 9-speed automatic transmission experienced severe drivability issues from programming defects. Software-controlled dog clutches proved incompatible with Honda's calibration, causing violent shaking/juddering, hesitation when accelerating from stops, and harsh downshifts at low speeds. Multiple class-action lawsuits filed against Honda.

The Honda Passport (2019-2023) with the ZF 9-speed automatic transmission experiences rough shifting, delayed shifting, harsh acceleration/deceleration, sudden loss of power, and transmission slipping into neutral unexpectedly. A class action lawsuit alleges the transmission control module (TCM) and powertrain control module (PCM) are miscalibrated, causing dangerous failures. Owners report the transmission downshifting harshly at highway speeds, hesitating when accelerating from a stop, and in severe cases, dropping into neutral while driving. Honda has issued multiple software updates (TSBs) but many owners report issues persist.

The ZF 9HP transmission produces rough and delayed shifting, loud noises during shifting, sudden harsh accelerations/decelerations, jerking/hesitating at all speeds, and loss of power. Problems stem from improper software calibration and electrical connection defects. Honda issued multiple TSBs but many issues persist until 2019 models.

The 4-speed automatic transmission (MAXA/M6HA) in the 1997-2001 Prelude is prone to premature failure, a problem shared with many late-1990s Honda automatic transmissions. The 3rd and 4th gear clutch packs wear prematurely, and the torque converter can develop shudder. High-mileage automatics often slip, flare between shifts, or fail to engage gears. Honda automatics of this era were undersized for the power output of the H22A engine.
