GM GENUINE PARTS Rear Output Shaft Seal 24232325 — OE Fit Automatic Transmission, Made in USA, Leak‑Resistant

GM Genuine Parts 24232325 is a factory‑spec automatic transmission rear output shaft seal built to restore a secure, leak‑resistant fit where the driveshaft exits the transmission.

This rear output shaft seal (part number 24232325) is manufactured to General Motors' original equipment specifications and supplied through the GM Genuine Parts program. It replaces the factory seal on compatible GM automatic transmissions to help stop fluid leakage, preserve internal lubricant levels, and maintain correct fitment at the driveshaft interface. Produced in the United States and validated by GM, the seal matches the form, fit, and function expectations of the vehicles it was designed for.

How does this seal prevent transmission fluid leaks?

The rear output shaft seal creates a tight barrier between the rotating output shaft and the transmission case, keeping ATF inside the gearbox while allowing the shaft to spin freely. Its design uses durable sealing materials selected to withstand heat, pressure, and exposure to transmission fluids.

• OE-matched dimensions ensure proper lip contact with the shaft.
• Material formulated to resist ATF and temperature cycling.
• Precision molded to reduce wobble and wear at the sealing edge.

Will this part fit my GM vehicle and how close is the fit to the original?

Part 24232325 is an exact replacement produced to GM’s factory specifications for vehicles that originally used this seal. Because it is a GM Genuine Part, it’s engineered to the same tolerances and interfaces as the OE component, simplifying installation and alignment.

• Direct replacement for the original factory seal when application matches.
• Manufactured to GM OE tolerances for predictable fitment.
• Backed by GM supply-chain validation to match original form and function.

What are the quality and origin details I should know?

The seal is produced in the United States and undergoes design and testing consistent with GM’s standards. Choosing a GM Genuine Part helps ensure the materials, molding, and dimensional controls conform to the same requirements used during vehicle assembly.

• Made in the United States to GM OE specifications.
• Engineered and tested under GM quality procedures.
• Supplied through the GM Genuine Parts program for authenticity.

How do I install or replace the rear output shaft seal?

Installation typically requires removal of the driveshaft and careful extraction of the old seal to avoid damaging the transmission bore. Pressing the new seal squarely into the housing and confirming correct lip orientation are important to ensure leak-free performance.

• Remove driveshaft and clean shaft and bore surfaces before installation.
• Use a seal driver or appropriate sized socket to press the seal evenly.
• Inspect shaft for scoring or wear that might compromise the new seal.

Who is this for: This GM Genuine Parts 24232325 rear output shaft seal is intended for owners, DIY mechanics, and professional technicians working on GM vehicles that require the factory replacement seal. It’s best suited for anyone restoring proper transmission sealing, replacing a leaking output seal, or maintaining OE-level reliability and fit on compatible GM automatic transmissions.
