P0894 on Toyota
Transmission Component Slipping
P0894 on Toyota vehicles indicates transmission component slipping. Au7o has documented this code across 1 Toyota model — most commonly on 4Runner. This generic transmission code means the PCM/TCM detected that a rotating component inside the transmission is slipping, by comparing input and output speeds and finding more difference than there should be for the commanded gear. Slippage indicates clutches or bands are not holding properly, which can quickly worsen and damage the transmission through overheating and accelerated wear. It often comes with rough or flaring shifts, reduced power, and overheating, and should be addressed promptly. Typical repair costs on Toyota range from $150 to $1,500, depending on the specific model and root cause.
Common Causes of P0894
- •Low, dirty, or burnt transmission fluid
- •Worn clutch packs or bands
- •Faulty shift or pressure control solenoid
- •Internal hydraulic/valve body problems
- •Worn torque converter
- •Faulty speed sensors giving false slip readings
- •General internal transmission wear
P0894 on Toyota by Model
Toyota 4Runner(1 issue)
- High-Mileage Harsh / Jerky Automatic Shifting from Valve-Body Pressure Issues2003-2024
On higher-mileage 4Runner automatics owners report harsh/abrupt shifts, jerky 3-2 downshifts, unstable RPM blips while coasting near 40 mph, and delayed engagement. The most common mechanical cause is valve-body pressure control wear - a sticking pressure-regulator or throttle valve, or a worn shift solenoid - which raises line pressure and slams the shifts, separate from the torque-converter shudder issue. RepairPal logs hundreds of reports of these trucks not shifting correctly at high mileage. Long-neglected, dark/burnt ATF accelerates it.
