On the 2015-2019 Chevrolet Silverado, silverados with the Hydra-Matic 8L90 (and 8L45) 8-speed automatic are widely reported to hesitate, then shudder, jerk, clunk or 'hard shift' when changing gears — some owners describe a shift so violent it feels like being rear-ended, plus a torque-converter-clutch shudder that feels like driving over rumble strips. The root cause is internal friction/hydraulic issues and torque-converter-clutch micro-slip, often worsened by the original transmission fluid breaking down, sending metal shavings through the unit. GM issued 13+ TSBs and a fluid change (to Mobil 1 Synthetic LV ATF HP / DEXRON-ULV) as the primary remedy, and the defect is the subject of a certified class action covering 2015-2019 Silverado and other GM models. Very high search and complaint volume.

This issue also affects: Buick Enclave, Buick Encore GX, Buick Regal

Common Symptoms

  • Shudder / vibration like driving over rumble strips
  • Harsh or violent hard shifts (clunk/bang)
  • Hesitation then surge on acceleration
  • Slipping or flaring between gears
  • Jerking at low speed / when slowing

How to Fix

First-line fix per GM TSB is a full transmission fluid flush/exchange to the updated low-viscosity fluid (Mobil 1 Synthetic LV ATF HP), which resolves many shudder cases. Persistent shudder or hard shifts may require torque-converter replacement, valve-body service, or transmission overhaul. Adding an auxiliary transmission cooler helps prevent recurrence. Document repairs — affected owners may qualify under the class-action settlement/lemon-law remedies.

Typical repair cost:$200 - $4,000

On the 2007-2019 Chevrolet Silverado, the 5.3L (and 6.2L) V8 with Active Fuel Management — GM's cylinder-deactivation system that drops the engine to 4 cylinders to save fuel — is notorious for collapsed AFM lifters. The special deactivating lifters (and the lifter oil-manifold/VLOM that feeds them) fail when oil pressure/timing to the lifter is compromised, causing the lifter roller to seize. A collapsed lifter no longer opens its valve, producing a dead-cylinder misfire, a loud ticking/tapping, rough idle and major power loss. If driven on, a collapsed lifter can wipe the camshaft lobe and destroy the cam, turning a lifter job into a top-end rebuild. This is consistently ranked the #1 Silverado engine problem and generates heavy forum and search traffic across the entire 2007-2019 AFM era. Disabling AFM (range tuner/AFM delete) is the common owner mitigation.

This issue also affects: Buick LeSabre, Buick Park Avenue, Buick Cascada

Common Symptoms

  • Loud ticking or tapping from top of engine
  • Cylinder misfire / rough idle
  • Check engine light with misfire code
  • Sudden loss of power
  • Engine knock
  • Excessive oil consumption alongside the tick

How to Fix

On a misfire/tick, pull the valve covers and inspect the AFM lifters and corresponding cam lobes. Standard fix is to replace all 8 AFM lifters (or convert to non-AFM lifters with an AFM-delete kit), the lifter guides, the VLOM/oil manifold, and head gaskets/bolts; if a cam lobe is wiped, the camshaft must be replaced too. Many owners install an AFM-disable tuner or a 'range' device to stop cylinder deactivation and prevent recurrence. Keep oil changes on time and avoid extended intervals — degraded/low oil pressure accelerates AFM lifter failure.

Typical repair cost:$1,500 - $4,500

On the 2014-2020 Chevrolet Silverado, the A/C condenser on K2XX-platform Silverados is a chronic failure point — the condenser develops cracks at the side spot-welds (thermal-stress fatigue) and the discharge line/hose can flex and crack, both of which leak refrigerant and leave the A/C blowing warm air. It was the #1 complaint on the 2014 model year. Because GM's condenser is a 'combi-cooler' with an integrated transmission oil cooler, a failure can affect both cabin cooling and transmission temps. GM acknowledged it with TSB PIT5331 (revised discharge tube + anti-flex bracket, part 23264893) and Special Coverage Adjustment 17336, extending warranty on the specific leak to 5 years / 60,000 miles — but never issued a safety recall. Heavily searched and reported.

This issue also affects: Chevrolet Tahoe

Common Symptoms

  • A/C blows warm or only mildly cool air
  • A/C cools then quits, especially in heat / at idle
  • Refrigerant leak (oily residue at condenser)
  • Hissing on shutdown
  • Bad/musty odor from vents

How to Fix

Have the system leak-tested (UV dye/electronic sniffer) to confirm the condenser/discharge line is the leak source. Replace the condenser with a revised/updated unit and install the redesigned discharge tube plus the anti-flex bracket per TSB PIT5331, then evacuate and recharge. Check eligibility for GM Special Coverage 17336 — if within 5 yr / 60k mi the repair may be free. Aftermarket condensers (e.g., GM3030306 cross-reference, OE 84537373) are common cost-saving replacements.

Typical repair cost:$400 - $1,200
