severe 50 complaints filed with NHTSA · avg repair $2,500 · see powertrain across all vehicles →
Owners have filed 50 powertrain complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
The failure pattern owners describe
Buyer takeaway: The 2006 Wrangler's six-speed manual transmission is plagued by a grinding 1st-to-2nd shift issue that owners report is unsafe and potentially damaging, while automatic models suffer from a known TCM computer failure causing harsh shifts. Several clutch and shifting components fail prematurely even at low mileage, and a major recall for clutch interlock switch parts has been impossible to complete due to parts unavailability.
The 2006 Wrangler's powertrain is a major weak point. Owners with the six-speed manual report a grinding or clipping noise during the 1st-to-2nd upshift that worsens when cold and improves with warmup—but persists. The shift is notchy, requiring drivers to either pause unusually long in neutral or double-clutch to complete it smoothly. Dealerships acknowledge the odd feel but call it normal and refuse warranty repair. Drivers report concern about transmission damage and safety risk from the power loss during the prolonged shift.
Automatic transmission owners face a different nightmare: the Transmission Control Module (TCM) integrated into the PCM fails chronically, causing violent upshifts, failure to shift from first to second, and over-revving. The only fix is full PCM replacement, but remanufactured units are unreliable—some owners report six defective units installed before one worked. Original PCM availability is severely constrained and priced 3–5 times higher than other years.
The clutch assembly itself is fragile. The plastic clip attaching the clutch rod to the pedal breaks unexpectedly, causing an audible pop and leaving the pedal slack to the floorboard—immediate loss of all clutch function. This can happen at 74 miles or after years of ownership. The hydraulic pushrod also snaps. A major recall (15V222000) was issued for the interlock switch, but replacement parts remain unavailable months or years after recall notification, leaving hundreds of owners unable to complete the repair. A second recall (06V147000) addressed clutch assembly issues.
One owner reported transmission fluid overheating, pressurizing, and spraying from the breather tube onto the exhaust manifold, creating an engine fire. The dealer denied both the fluid and fire were possible.
Some owners report the vehicle will roll away in reverse when parked because the clutch interlock switch allows the key to be removed without the transmission in Park. Front-end shaking at highway speeds is a separate but widespread complaint; some track bar failures occurred at 74,000 miles with recurrence shortly after repair. Dealers have shown little willingness to diagnose or repair these issues.

Failure modes owners describe
Manual transmission hard/grinding 1st-to-2nd shift
Six-speed manual transmissions grind, clipping, or pop out of second gear during upshift from first. Shift requires excessive delay in neutral or double-clutching to complete smoothly. Problem worse when cold, improves with warmup but persists. Owners report concern about transmission damage and safety risk due to power loss during the prolonged shift.
When: Typically within first 500-1600 miles; some reports note continuation after extended driving
Symptoms owners cite: Loud grinding or clipping noise during 1st-to-2nd upshift; Second gear feels unsynchronized, requiring delay or double-clutch; Sensation of gear teeth hitting or bouncing; Reluctance to fully engage second gear, requiring forced engagement; Poor acceleration after shift due to RPM drop; Condition worse when transmission cold
Repairs/costs cited: Dealers report difficulty reproducing problem and inability to identify root cause. Linkage adjustment and lubrication attempted without lasting resolution. No confirmed successful repair identified in narratives.
Recalls/TSBs owners mention: Dealers acknowledge issue but label as 'normal for this vehicle' or unable to replicate during testing. No recall issued for this specific condition.
Clutch pedal attachment failure (plastic clip/bracket)
The plastic clip or bracket connecting the clutch rod to the clutch pedal breaks or fails, causing immediate loss of clutch function. Pedal goes slack to floorboard with audible pop from under dash. Vehicle becomes undriveable until repair performed. Failure occurs with minimal mileage. Part is subject to recall 15V222000 and 06V147000.
When: Reported at very low mileage: 74 miles, 600 miles, and instances after years of ownership; failures occur during routine gear shifts or key removal
Symptoms owners cite: Plastic clip breaks with audible pop from under dash; Clutch pedal goes slack to floorboard with no resistance; Complete loss of clutch control; Unable to shift gears or control vehicle
Repairs/costs cited: Plastic clip/bracket must be replaced. Some covered under warranty at no cost; warranty repairs confirmed. Replacement part availability has been problematic (see recall delays). One owner reports dealer replaced unit under recall but replacement part is also defective.
Recalls/TSBs owners mention: NHTSA campaigns 15V222000 (clutch interlock switch) and 06V147000 (clutch assembly). Multiple owners report extensive delays—months to years—in obtaining recall parts, with dealers unable to order or track availability. Some dealerships unable to perform recall due to unavailable parts.
Clutch hydraulic rod/pushrod failure
Clutch hydraulic unit actuating rod snaps in two, disabling clutch function. Failure occurs during routine operation with vehicle parked or during low-speed gear changes. Related to recall 15V222000.
When: Reported after 15 miles and at various mileages during normal operation
Symptoms owners cite: Clutch pedal snaps and dangles; Loss of clutch hydraulic pressure and function; Unable to operate clutch
Repairs/costs cited: Hydraulic rod/unit must be replaced. Requires towing to dealer. Replacement parts must be ordered, extending downtime.
Recalls/TSBs owners mention: Covered under warranty (reported at least one warranty repair). Subject to recall 15V222000.
Automatic transmission TCM/PCM failure—harsh shifting, 1st-to-2nd hang
Transmission Control Module (TCM) integrated within the PCM fails, causing harsh or violent shifting, failure to upshift from first to second, over-revving, and loud thuds/clunks during shift attempts. Problem can be temporarily masked by resetting the computer via battery disconnect. Requires full PCM replacement for lasting repair. Remanufactured PCMs show poor reliability, often requiring multiple replacements.
When: Reported at various mileages; one case at 73,000 miles with recurrence after initial reprogram and PCM replacement
Symptoms owners cite: Harsh or violent upshift from 1st to 2nd gear; Failure to shift from 1st to 2nd; Over-revving of engine during attempted shift; Loud thuds or clunks during shift; Check engine light may appear; Intermittent starting failure
Codes mentioned: P0218 - High temperature operation activated, P0714 - Transmission temp sensor intermittent, P0613 - Internal TCM problem
Repairs/costs cited: PCM reprogramming provides temporary relief only. Full PCM replacement is necessary fix. Remanufactured units unreliable; multiple replacements often required. One owner reports six different remanufactured units installed in 90 days before one worked. Original PCM parts availability reported as critical shortage, with prices 3-5 times higher than other model years.
Recalls/TSBs owners mention: Chrysler has known of this issue since 2006 and has made no systematic recall or TSB response. Dealers and independent mechanics report Chrysler offers no support or parts solutions. Aftermarket companies have developed fixes manufacturer has not provided.
Transmission fluid overpressurization and leakage from breather
Transmission fluid overheats and pressurizes, forcing fluid to exit from the breather tube located on the right side of the transmission case. Fluid contacts exhaust manifold, creating smoke and fire hazard. Transmission case remains intact with no other leak sources identified.
When: Occurred during highway driving at 60 mph; event may relate to downshift behavior
Symptoms owners cite: White smoke from rear of vehicle; Transmission fluid visible in engine compartment on right side; Engine compartment fire (small, easily extinguished); Fluid discharged from breather tube on right side of transmission
Repairs/costs cited: Repair estimate $3,800–$4,000 provided by dealer. Owner did not authorize repair; condition involves fluid leak and fire risk.
Recalls/TSBs owners mention: Dealer denied possibility of transmission fluid causing fire and denied fluid could come from breather tube. Dealer provided repair estimate without diagnostic inspection.
Clutch assembly noise and linkage issues
Loud rattling or popping noise originates from clutch linkage or throw-out bearing area, particularly when idling in neutral with clutch disengaged. Some owners report loud whistling when coasting above 2000 RPM with clutch out. Dealership diagnostic efforts unsuccessful.
When: Reported at 40,476 miles and during routine idling; timing after throw-out bearing replacement noted in one case
Symptoms owners cite: Loud rattling sound when idling in neutral with clutch out; Loud whistling when coasting above 2000 RPM with clutch out; Hard vibration under clutch; Popping sound when switching gears
Repairs/costs cited: Throw-out bearing replacement attempted in one case without resolving subsequent whistling noise. Dealership unable to diagnose root cause of noise. Multiple dealership visits unsuccessful.
Recalls/TSBs owners mention: Dealership claims noise is 'normal wear noise' or 'normal' for vehicle. No successful repair identified.
Clutch slipping out of gear / loss of clutch control
Clutch slips out of gear or loses engagement, requiring owner to manipulate gears repeatedly during operation. One instance involved vehicle rolling backward unintended while parked after key removal without transmission in Park. Related to recall 06V147000.
When: Timing variable; one instance at 54,700 miles during unloading; slipping issue timing not specified
Symptoms owners cite: Clutch slips out of engaged gear during driving; Repeated need to re-engage gears during trip; Vehicle rolls away when parked if not in Park (no clutch interlock function)
Repairs/costs cited: Owner must repeatedly manipulate gears to regain engagement during driving. Vehicle rolling incident was not repaired.
Recalls/TSBs owners mention: Related to recall 06V147000 (clutch assembly); recall information limited in narratives.
Burnt/failed clutch at low mileage
Clutch burns up or fails prematurely at very low mileage with no apparent owner abuse or excessive wear. Owner receives sudden loss of acceleration followed by inability to engage any gear; vehicle coasts in neutral and gives black smoke puff before becoming immobile.
When: Occurred under 15,000 miles, with sudden onset during normal driving
Symptoms owners cite: Sudden loss of acceleration while in gear; Unable to engage any gear; stuck in neutral; Black smoke puff from tailpipe; Vehicle becomes immobile
Repairs/costs cited: Dealer diagnosis: worn/burnt clutch, requiring $1,200 repair. Owner disputes wear diagnosis, believing failure was defect not wear.
Recalls/TSBs owners mention: No recall or warranty extension noted; repair charged to owner despite low mileage.
Engine stalling/cut-out and hesitation after refueling
Vehicle stalls or hesitates and bogs down immediately after refueling and pulling away from pump. Stalling can occur multiple times during initial acceleration. Engine revs and surges erratically. Creates safety hazard in traffic situations.
When: Occurs consistently after refueling; one incident on interstate with heavy traffic
Symptoms owners cite: Engine stalls after refueling; Hesitation and bogging after pulling away from pump; Multiple stalls in single trip; Engine surge and rough idle after stall recovery; Rough engine response
Repairs/costs cited: No repair details provided in narratives.
Recalls/TSBs owners mention: No manufacturer response documented.
Shift lever failure to engage Park / shifter assembly failure
Shift lever fails to shift fully into Park position or shift cable bushing breaks, rendering automatic transmission shifter inoperable. Plastic component of shifter breaks. Vehicle cannot be safely parked with transmission in gear.
When: Timing not specified in one case; shift cable bushing failed twice for same owner
Symptoms owners cite: Gear lever will not shift into Park position; Shift cable bushing broke; shifter becomes inoperable; Shift cable failure occurred twice for same vehicle
Repairs/costs cited: Shift lever assembly or shift cable/bushing replacement required. Repeated failure noted (cable failed twice).
Recalls/TSBs owners mention: Related to recall 05V46000 (power train); one VIN was not included in recall campaign.
Front end vibration and shaking (steering/suspension interaction with drivetrain)
Severe front end shake and vibration under driving, particularly at speeds above 45-50 MPH, on rough roads, or over bumps. Entire vehicle and steering wheel shake uncontrollably. Issue recurs repeatedly during single trip. Problem reported as widespread among 2006 Wrangler owners but unaddressed by manufacturer. One case also reports related track bar wear requiring replacement at 74k miles.
When: Reported at 45-50 MPH and higher speeds; recurring multiple times per trip. Track bar wear noted at 74,000 miles with recurrence 20,000 miles later.
