Transmission Defects in Kansas Lemon Law

Transmission defects are among the most settlement-favorable Kansas Lemon Law cases — visible, drivability-impairing, and well-documented in pattern-defect litigation.

Ford 6F35 / 8F35 / 10R80 transmissions

Ford torque-converter automatics in:

• 6F35 (6-speed): Escape (2013-2019), Fusion (2013-2020), Focus (2012-2018), Edge (2011-2018).
• 8F35 (8-speed): Edge (2019-2024), Bronco Sport (2021+), Escape (2020+), Maverick.
• 10R80 (10-speed): F-150 (2017-2024), Mustang (2018+), Expedition (2018+), Navigator (2018+), Ranger (2019+).

Defect mechanism: harsh shifting, shudder, slipping between gears, sometimes catastrophic failure. 10R80 particularly notorious — Federal class-action ongoing (Vargas et al. v. Ford). 6F35 / 8F35 have similar patterns.

Kansas relevance:

• Cross-state Ford KC Claycomo (W.D. Mo. — F-150 home plant; 10R80 production).
• Rural KS F-150 / Super Duty / Ranger market.
• Ford Bronco Sport in Olathe / Overland Park / Johnson County market.

GM 8L45 / 8L90 / 9T50 / 9T65 transmissions

GM Hydra-Matic automatics in:

• 8L45 / 8L90 (8-speed RWD): Silverado / Sierra (2015-2024), Tahoe / Suburban / Yukon (2015-2024), CT6 (2016-2019), CT5, Camaro (2016-2024), Corvette C7 (2015-2019).
• 9T50 / 9T65 (9-speed FWD/AWD): Equinox (2018+), Acadia (2017+), Traverse (2018+), Enclave (2018+), Cadillac XT4 (2019+ — built at GM Fairfax KS), XT5.

Defect mechanism: shudder under light throttle (5-25 mph), harsh shifts, slipping. GM Service Bulletins and TSBs issued repeatedly without permanent fix. Federal class settlement (Speerly et al. v. GM) for 8-speed but pattern continues; 9-speed similar pattern.

Kansas relevance:

• GM Fairfax Kansas Assembly — Cadillac XT4 9T50 — home-venue dynamics for D. Kan. Kansas City Division.
• KS-built XT4 transmission defects create paradigm home-state-defendant cases.

Nissan Jatco CVT (RE0F11A / JF015E / JF016E / JF017E)

Nissan’s continuously-variable transmission in:

• Nissan: Sentra (2007+), Altima (2007+), Versa (2007+), Rogue (2008+), Pathfinder (2013+), Murano (2008+), Maxima (2007-2014).
• Infiniti: QX60 (2014+), JX35.

Defect mechanism: belt slippage, judder, hesitation, shudder, occasional catastrophic failure. Multiple class settlements (Falk et al., Madrid et al.). Manufacturer extended warranty to 84-month / 84,000-mile on many affected models.

Kansas relevance:

• Nissan dealer network across all KS metros.
• Sentra / Altima / Rogue are major KS commuter/budget-sedan / SUV market.

Honda CVT (Civic / Accord / CR-V / HR-V)

Honda’s CVT in:

• Honda: Civic (2016+), Accord (2018+), HR-V (2016+), CR-V (2017+), Insight (2019+).

Defect mechanism: belt judder, shudder, hesitation. Less catastrophic than Nissan Jatco but still substantial-impairment defect under § 50-645.

Kansas relevance: Honda Civic / Accord / CR-V are dominant KS commuter vehicles.

Hyundai/Kia 7DCT / 8DCT dual-clutch

Hyundai-Kia dual-clutch automatics in:

• Hyundai: Veloster (2019+), Elantra GT (2018-2020), Kona (2018+), Sonata Limited (2020+).
• Kia: Forte GT (2019+), Soul GT (2020+), Seltos (2021+).
• Genesis: G70 (2018+).

Defect mechanism: harsh engagement from stop, hesitation, shudder, occasional bucking. Dual-clutch programming and clutch-pack wear issues.

Kansas relevance: Hyundai-Kia growing market share in KS — Kona / Seltos / Soul popular in younger-demographic markets (Lawrence, Manhattan).

Stellantis 9-speed (ZF 948TE)

ZF 9HP / 948TE transmission in:

• Chrysler: Pacifica (2017+).
• Dodge: Journey (2014-2020 — discontinued).
• Jeep: Cherokee (2014+), Renegade (2015+), Grand Cherokee (2015-2021 WK2; 2022+ WL), Compass (2017+).
• Ram: ProMaster (variants).

Defect mechanism: harsh shifts, hesitation, software-flashing without permanent fix. Multiple TSBs and software updates without resolution.

Kansas relevance: Stellantis dealer network across all KS metros; Jeep Cherokee / Grand Cherokee popular in Johnson County / Wichita markets.

Ford 6.7L Power Stroke + 10R140 transmission (Super Duty)

Ford 10R140 10-speed transmission in F-Super-Duty (2020+) — different ratios and capacity from F-150’s 10R80. Similar pattern of harsh-shift / shudder issues during early production years.

Kansas relevance: rural KS / agricultural Super Duty market.

How transmission defects meet § 50-645(d)

Transmission defects are highly diagnosable and well-documented:

• Track 1 (4 attempts) — typically achieved within 6-9 months as dealer escalates from software flash → TCM reprogramming → valve body → torque converter → full transmission replacement.
• Track 2 (30 days OOS) — torque-converter replacements and transmission rebuilds typically require 7-14 days each; cumulative OOS adds up quickly.
• Track 3 (10 cumulative attempts) — vehicles with transmission + additional defects (e.g., GM XT4 with transmission + infotainment + electrical attempts) reach Track 3 quickly.

Pattern-defect discovery leverage

In federal D. Kan., transmission-defect cases typically produce extensive pattern-defect discovery:

• Manufacturer’s TSB / field action history.
• Internal field engineer reports.
• NHTSA complaint database parallel cases.
• Class-action settlements and ongoing class certification motions.

This drives substantial settlement leverage — manufacturer doesn’t want internal field-reporting data made public in additional venues.

Bottom line

Transmission defects are paradigm Kansas Lemon Law cases. GM 9T50 in Cadillac XT4 (GM Fairfax KS home-venue) creates particularly strong home-state-defendant dynamics. Ford 10R80 (F-150 cross-state KC Claycomo), Nissan Jatco CVT, Honda CVT, Stellantis 9-speed, Hyundai-Kia dual-clutch all produce viable § 50-645(d) cases. Track 1 and Track 2 typically easily satisfied; pattern-defect discovery drives settlement.
