Description

Products Description

Should be replaced when you have the transmission out.

The Transmission Gasket Front (also known as front transmission case gasket, transmission housing gasket, or gearbox front gasket) is a critical sealing component in your ISUZU vehicle's manual transmission system. It seals the joint between the front transmission case and the main gearbox housing, preventing transmission fluid from leaking out while keeping dirt, dust, and moisture from entering the gearbox .

This front transmission gasket is specifically designed for ISUZU PHR, NHS, TFR, UBS, and UCS series vehicles .OE cross reference: 8944218630, 8944739460, 8970835890, 8-94421863-0, 8-94473946-0, 8-97083589-0, 1701309-44 . widely used in Asia-Pacific, Middle Eastern, South American, and African markets.

The front transmission gasket is installed between the transmission case sections. It serves as a barrier, preventing transmission fluid from escaping while simultaneously keeping contaminants out . Without a proper sealing gasket, transmission fluid leaks can occur, leading to low fluid levels, difficult gear shifts, grinding noises, and eventual transmission failure . This China ISUZU (Qingling) Quality gasket restores the factory seal, ensuring reliable transmission performance and preventing costly repairs.

Key Symptoms of a Front Transmission Gasket Leak:

Red or Brown Puddles: A noticeable leak of red, pink, or dark brown fluid directly under the front of the transmission, commonly behind the engine.
Burning Odor: Overheating fluid escaping onto hot engine components creates a distinct burning smell.
Low Fluid Level: A consistent need to top off transmission fluid, as seen on the dipstick.
Delayed/Rough Gear Shifts: The transmission hesitates, jerks, or struggles to change gears properly due to lack of hydraulic pressure.
Gear Slippage: The engine RPM increases, but the vehicle does not speed up accordingly.
Warning Lights: The "Check Engine" or transmission warning light illuminates on the dashboard.
Unusual Noises: Humming or whining sounds produced by the transmission, suggesting a lack of lubrication

FAQ

Q1: What is the difference between Transmission Gasket Front and other transmission gaskets?

A: The Transmission Gasket Front (also called front transmission case gasket) specifically seals the joint between the front transmission case and the main gearbox housing. Other transmission gaskets include rear case gaskets, shift tower gaskets (quad box), and side cover gaskets. This part is specifically referenced as "GASKET; GEAR" in ISUZU parts catalogs .

Q2: What does "China ISUZU (Qingling) Quality" mean?

A: Qingling Motors is ISUZU's long-term joint venture partner in China, producing ISUZU-licensed commercial vehicles since 1985. China ISUZU Quality parts are manufactured to the same specifications as original equipment supplied to ISUZU's China production lines – including the popular 4JB1-powered trucks and pickups sold globally.

Q3: Will this fit my TFR with the 4JB1 engine?

A: Yes. The 4JB1 (2.8L diesel) is one of the primary engines for which this front transmission gasket is designed. This gasket fits TFR/TFS pickups and UBS/UCS SUVs equipped with manual transmissions, including Thailand, Europe, Middle East, LHD, and RHD market versions .

Q4: Is this gasket for automatic or manual transmission?

A: This gasket is designed for manual transmission vehicles. It is a "GASKET; GEAR" component used in ISUZU manual gearboxes .

Q5: How many gaskets do I need for a transmission rebuild?

A: One front transmission gasket per vehicle. However, a full transmission rebuild may require additional gaskets including rear case gaskets, shift tower gaskets, and side cover gaskets. Please consult your vehicle's service manual.

Q6: Do I need sealant with this gasket?

A: This is a dry-fit gasket designed to seal without additional sealant. However, always consult your vehicle's factory service manual for specific recommendations.

Q7: What is the difference between OE numbers 8944218630, 8944739460, and 8970835890?

A: These are different part number formats or slight variants for the same transmission front gasket across different markets and production years. All are interchangeable for the applications listed. The number 1701309-44 is an alternative format used in some markets.

Q8: What happens if I don't replace a leaking front transmission gasket?

A: A compromised gasket can lead to fluid leaks, resulting in low fluid levels that cause gears to grind or slip. Over time, this can lead to irreparable transmission damage and potentially leave the vehicle inoperable . Severe leakage can starve the gearbox of oil, leading to overheating and costly rebuilds
