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 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.
