2024+ Tacoma - Transmission & Transfer Case Fluids

[4gtacoadmin]

This thread covers the official fluid specifications and safety requirements for all transmission systems in the 2024+ Toyota Tacoma (4th Generation), including automatic transmission, manual transmission, transfer case, and clutch. Information compiled from Owner's Manual pages 617-618.

Tacoma Transmission Fluids: ATF, Manual & Transfer Case​

Critical Safety Notices from Owner's Manual:

General Fluid Capacity Notice (Page 617):
The fluid capacity is a reference quantity. If replacement is necessary, contact your Toyota dealer.

Automatic Transmission Fluid Type Warning (Page 617):
Using transmission fluid other than the above type may cause abnormal noise or vibration, or damage the transmission of your vehicle.

Transfer Case Fluid Source Requirement (Page 618):
Use Toyota approved "Toyota Genuine Transfer Gear oil LF" or an equivalent of matching quality to satisfy the above specification. Please contact your Toyota dealer for further details.

Manual Transmission Performance Note (Page 618):
Please be aware that depending on the particular characteristics of the gear oil used or the operating conditions, idle sound, shift feeling and/or fuel efficiency may be different or affected. Toyota recommends to use "TOYOTA Genuine Manual Transmission Gear Oil" to achieve optimal performance.

Transmission Fluid Specifications​

Automatic Transmission (8-Speed)​

Capacity:
12.4 qt. (11.7 L, 10.3 Imp. qt.)
Source: Page 617

Fluid Type:
Toyota Genuine ATF WS
Source: Page 617

Technical Context:
The 8-speed automatic transmission in the 4th Gen Tacoma uses ATF WS (Automatic Transmission Fluid World-Standard). This synthetic fluid formulation is critical for optimal shift quality and transmission longevity. ATF WS has lower viscosity than previous generations, optimized for fuel economy and cold-start performance in the turbocharged engine environment. Using non-approved transmission fluid can cause shift hesitation, noise during gear changes, and potential transmission damage requiring dealer repair.

Manual Transmission (with iMT Intelligent Manual Transmission)​

Capacity:
2.6 qt. (2.5 L, 2.2 Imp. qt.)
Source: Page 617

Gear Oil Type:
Toyota Genuine Manual Transmission Gear Oil GL-3 (GL-4) or equivalent
Source: Page 617

Recommended Viscosity:
SAE 75W-90
Source: Page 617

Technical Context:
The manual transmission uses GL-3 or GL-4 gear oil with SAE 75W-90 viscosity. This specification is critical because transmission gear oils significantly affect shift feel, idle quality, and fuel economy. Toyota Genuine gear oil is engineered specifically for the Tacoma's synchronizer system and clutch materials. Lighter or heavier weight oils, or inferior quality gear oils, will noticeably change shift characteristics and may reduce transmission life.

Transfer Case (4WD Models Only)​

Factory Fill:
Toyota Genuine Transfer Gear oil LF
Source: Page 618

Capacity:
1.2 qt. (1.1 L, 1.0 Imp. qt.)
Source: Page 618

Oil Type:
Toyota Genuine Transfer gear oil LF or equivalent
Source: Page 618

Recommended Viscosity:
SAE 75W
Source: Page 618

Technical Context:
The transfer case fluid (Toyota Genuine Transfer Gear Oil LF) is a specialized lubricant optimized for 4WD operation, including crawl control engagement and multi-terrain select modes. The "LF" designation indicates this is a newer formulation with enhanced friction characteristics for modern Toyota 4WD systems. For 2WD models, transfer case service is not required. For 4WD models, the transfer case should be serviced during maintenance intervals as specified in the Toyota Maintenance Schedule (separate document from this Owner's Manual).

Clutch System​

Clutch Free Play Specification:
0.2 - 0.6 in. (5 - 15 mm)
Source: Page 618

Clutch Fluid Type:
FMVSS No. 116 DOT 3 or SAE J1703
Source: Page 618

Technical Context:
The clutch uses standard DOT 3 brake fluid (same as the hydraulic brake system). Free play specifications are critical for clutch engagement feel and proper operation. Clutch service is typically not required during normal operation; however, if free play exceeds specifications, dealer service is recommended.
