2012 LADA GRANTA

Typical onset: 50,000-90,000 mi

Symptoms: harsh or delayed shifting between gears, slipping in 2nd or 3rd gear under load, transmission shuddering during acceleration, check engine light with P0745 or P0730 codes, complete loss of forward gears

Fix: The Jatco JF414E transmission suffers from valve body wear, failing shift solenoids, and torque converter clutch issues. Band-aid fixes like solenoid replacement (2-3 hours labor) rarely last; most need full valve body replacement (5-6 hours) or complete rebuild (12-15 hours). Torque converter replacement adds another 3-4 hours if done separately.

Estimated cost: $1,800-4,500

Typical onset: 60,000-100,000 mi

Symptoms: red ATF fluid pooling under vehicle, low transmission fluid warnings, overheating transmission in warm weather, oil cooler lines weeping at crimp connections

Fix: The external transmission cooler and its hard lines corrode and crack, especially in road-salt regions. Cooler itself is 2 hours to replace; if lines are rotted, expect another hour wrestling rusted fittings. Always replace both cooler and lines together to avoid comebacks.

Estimated cost: $300-600

Typical onset: 70,000-120,000 mi

Symptoms: heavy clunk when shifting from Park to Drive, vibration at idle that disappears in Neutral, visible engine/trans movement when revving, worn rubber visibly torn or oil-soaked

Fix: The rear transmission mount uses soft rubber that deteriorates rapidly. Replacement is straightforward (1.5-2 hours) but requires supporting the transmission from below. OEM mounts last 40-50k miles; aftermarket polyurethane versions last longer but transmit more NVH.

Estimated cost: $150-280

Typical onset: 40,000-70,000 mi

Symptoms: rough idle and hesitation under acceleration, stalling when fuel tank below 1/4, long cranking before start, loss of power on highway grades

Fix: The in-line fuel filter clogs much earlier than spec'd 60k interval, likely due to poor fuel quality in target markets or tank rust. Filter sits under vehicle near tank (1 hour labor). Always inspect fuel tank condition when replacing; internal rust is common and will kill new filters quickly.

Estimated cost: $80-150

Typical onset: 80,000-130,000 mi

Symptoms: sloppy shifter feel with excessive play, difficulty selecting Park or Reverse, gear indicator not matching actual gear, plastic bushing visible at shifter base falling apart

Fix: The shift cable uses plastic bushings at both ends that wear oval-shaped, creating slop. Cable replacement is 1.5 hours and requires underhood and interior access. Some techs rebuild with brass bushings to eliminate repeat failures, adding 0.5 hour.

Estimated cost: $120-250

Typical onset: 55,000-85,000 mi

Symptoms: erratic shifting patterns day-to-day, occasional 3-2 or 2-1 flare during downshifts, transmission stuck in limp mode (3rd gear only), multiple solenoid codes stored simultaneously

Fix: Valve body bore wear allows pressure loss; solenoids stick from varnish buildup. Solenoid replacement alone (3 hours R&R pan and valve body) is temporary—bores are scored. Proper fix is remanufactured valve body (5-6 hours), but at that labor depth, many owners opt for full transmission rebuild instead.

Estimated cost: $800-1,500
