2011 UAZ PICKUP

Typical onset: 70,000-110,000 mi

Symptoms: harsh or delayed 3-4 upshift, transmission stays in lower gear on highway, check engine light with overdrive solenoid codes, erratic shifting under load

Fix: Overdrive solenoid and individual shift solenoids fail due to heat and fluid contamination. Requires pan drop, filter service, and solenoid replacement. 3-4 hours labor. Sometimes cascades into needing the input speed sensor replaced at the same time due to wiring harness degradation.

Estimated cost: $600-1,200

Typical onset: 60,000-100,000 mi

Symptoms: speedometer drops to zero intermittently, harsh or no shifts, transmission goes into limp mode, ABS and traction control lights illuminate

Fix: The input speed sensor on the ZF box is exposed to heat and vibration, causing connector corrosion and internal sensor failure. Replacement requires access from underneath, 1.5-2 hours labor. Recommend inspecting wiring harness and cleaning connector during replacement.

Estimated cost: $250-500

Typical onset: 80,000-130,000 mi

Symptoms: transmission fluid pooling under vehicle, burnt transmission fluid smell, transmission overheating warning, pink fluid mixing with coolant in radiator overflow

Fix: Steel cooler lines rust through at mounting points, and the factory cooler itself can crack internally, mixing ATF with coolant. Full cooler replacement plus line work runs 4-6 hours. Must flush cooling system and transmission after contamination event. Catastrophic if ignored — can destroy transmission and overheat engine.

Estimated cost: $800-1,800

Typical onset: 50,000-90,000 mi

Symptoms: squealing or chirping from front of engine, rhythmic clicking or rattling, belt wear or fraying on one edge, visible wobble in pulley when engine running

Fix: The 2.7L Iveco engine uses a spring-loaded tensioner and separate idler pulley that both fail prematurely due to poor bearing quality. Replace both as a set with new belt. 1.5-2 hours labor. Failure can strand you if belt shreds.

Estimated cost: $300-550

Symptoms: rough idle when cold, hesitation or stumble on acceleration, hard starting after sitting, loss of power under load

Fix: The 2.7L is extremely sensitive to fuel quality and the inline fuel filter clogs faster than domestic trucks, especially with ethanol-blend fuels. Replace every 15,000-20,000 miles instead of book interval. Filter replacement is straightforward, 0.5 hours, but diagnosis of driveability issues often leads here first.

Estimated cost: $80-150

Typical onset: 70,000-120,000 mi

Symptoms: clunking when shifting from park to drive, excessive vibration at idle in gear, visible transmission sag when inspected from below, shifter feels loose or notchy

Fix: Rubber mount between transmission and crossmember tears and collapses, allowing driveline movement. Replacement requires supporting transmission, 1-2 hours labor. Often overlooked until shift cable geometry is affected.

Estimated cost: $200-400

Typical onset: 90,000-150,000 mi

Symptoms: rough idle with hunting RPM, coolant loss with no visible external leak, white smoke from exhaust on startup, check engine light with lean codes

Fix: The composite intake manifold gasket degrades, causing vacuum leaks and sometimes internal coolant seepage into cylinders. Requires manifold removal, gasket set, and coolant flush. 4-5 hours labor. Must pressure-test cooling system afterward.

Estimated cost: $600-1,100
