T5 Jeep Transmission For Sale: Your Comprehensive Guide to Finding the Right Gear
Understanding the T5 Jeep Transmission
The Borg-Warner T5 is a five-speed manual transmission that gained widespread popularity across various automotive platforms, including a significant presence in American Motors Corporation (AMC) Jeeps. Characterized by its aluminum casing, the T5 was relatively lightweight, contributing to better fuel economy and a more agile feel compared to some of its heavier counterparts.
Key Features & Applications:
- 5-Speed Manual: Offering five forward gears and one reverse, it provided a more modern driving experience than older 3- or 4-speed units.
- Aluminum Casing: Contributed to its lighter weight, a benefit for the often-underpowered engines of classic Jeeps.
- Gear Ratios: T5 transmissions had various gear ratios depending on the specific application and year. For Jeeps, common ratios often featured a lower first gear for off-road capability and a reasonable overdrive fifth gear for highway cruising. It’s crucial to note that different T5 variants exist (e.g., Ford, GM, AMC), and the Jeep-specific versions were typically matched to AMC engines.
- Common Jeep Models: The T5 was predominantly found in:
- CJ-5 (late models): Particularly those with the 2.5L and 4.2L engines.
- CJ-7: A very common transmission choice for both the 2.5L four-cylinder and 4.2L inline-six.
- CJ-8 Scrambler: Like the CJ-7, it was a popular fit.
- Early YJ Wrangler (1987-1988): Primarily with the 4.2L engine before the AX-15 became standard.
While generally considered a light-duty transmission compared to beefier alternatives like the T-18 or SM465, the T5 earned a reputation for reliability when not subjected to excessive abuse (e.g., large tires, heavy off-roading, or powerful engine swaps without proper re-gearing). Its direct feel and relatively smooth shifting made it a popular choice for daily driving and moderate trail use.
Why Buy a T5 Jeep Transmission? Benefits and Use Cases
The decision to seek out a T5 Jeep transmission for sale often stems from several compelling reasons:
- Authentic Restoration and Period Correctness: For purists restoring a vintage CJ or early YJ, a T5 is essential for maintaining the vehicle’s original specifications and value.
- Direct Replacement: If your original T5 has finally given up the ghost due to wear, neglect, or abuse, finding a direct replacement is often the most straightforward and cost-effective solution.
- Budget-Friendly Option: Compared to swapping in a modern, heavy-duty transmission, sourcing and installing a T5 can be significantly more economical, especially if you’re comfortable with DIY work.
- Simplicity and Maintainability: The T5 is a mechanical marvel with fewer complex electronics than newer transmissions, making it more approachable for diagnosis and repair by the average enthusiast.
- Lightweight Advantage: Its aluminum construction helps keep the overall weight of the Jeep down, which can subtly improve performance and handling.
- Mild Engine Swaps: For those performing engine swaps that aren’t significantly more powerful than the original (e.g., a stock 4.0L swap into a CJ), a T5 might suffice, especially with proper gearing and careful driving.
Where to Find T5 Jeep Transmissions For Sale
The hunt for a T5 can lead you down several avenues, each with its own advantages and potential pitfalls:
-
Online Marketplaces:
- eBay: A vast selection, often with nationwide shipping. Look for sellers with good reputations and detailed descriptions.
- Craigslist & Facebook Marketplace: Excellent for local finds, potentially saving on shipping costs and allowing for in-person inspection. Search in broader regions if you’re willing to travel.
- Dedicated Jeep Forums & Groups: Many online communities have "For Sale" sections where enthusiasts sell parts. These can be great for finding well-maintained units from knowledgeable sellers.
-
Specialized Jeep Parts Dealers: Several companies specialize in vintage Jeep components. They may offer new old stock (NOS) units (rare and expensive), good used units, or professionally rebuilt transmissions with warranties. Examples include Quadratec, Morris 4×4 Center, and smaller independent shops.
-
Salvage Yards / Auto Wreckers: A roll of the dice, but potentially the cheapest option. You might find a T5 in a donor Jeep, but its condition will be unknown. Always inspect thoroughly for fluid, cracks, and input/output shaft play.
-
Transmission Rebuilders: Many transmission shops that specialize in older vehicles often have T5 cores they can rebuild or already have rebuilt units for sale. This option typically comes with a warranty, offering peace of mind.
-
Auto Auctions: Sometimes, entire vehicles with good T5s might appear in online or physical auto auctions, particularly those specializing in salvaged or classic vehicles.
Key Considerations Before Buying
Purchasing a used or rebuilt T5 requires careful due diligence. Here’s what to look for and consider:
-
Condition:
- Used: The most common and affordable. Ask for details on the donor vehicle (mileage, reason for removal). Inspect for leaks, cracks, damaged splines, and excessive shaft play.
- Rebuilt: A safer bet, as internal components have been replaced. Always inquire about the rebuilder’s reputation and warranty.
- New Old Stock (NOS): Extremely rare and expensive, typically only for concours-level restorations.
-
Gear Ratios: The T5 came with different gear sets. Verify the specific ratios of the unit for sale and ensure they match your vehicle’s needs (engine, axle gears, tire size, intended use). A lower first gear might be desirable for off-roading, while a taller fifth gear improves highway economy.
-
Input Shaft / Bell Housing Compatibility: Jeep T5s typically have an AMC bolt pattern for the bell housing. Ensure the transmission you’re looking at matches your engine’s bell housing bolt pattern. While adapters exist, they add cost and complexity.
-
Output Shaft / Transfer Case Compatibility: The T5 needs to mate correctly with your transfer case (e.g., Dana 300, NP207, NP231). Check the spline count and bolt pattern of the output shaft.
-
Shifter Tower: Confirm the shifter tower is included and in good condition, as these can vary slightly and finding a specific one later can be challenging.
-
Reputation of the Seller: Especially for private sales or smaller shops, research the seller’s reputation. Look for reviews or ask for references.
-
Warranty: Does the seller offer any warranty, even a short one? This is crucial for rebuilt units.
-
Shipping Costs: T5 transmissions are heavy. Factor in freight shipping costs if buying from a distant seller, as they can significantly impact the total price.
Tips for a Successful Purchase
- Ask for Detailed Photos and Videos: Don’t just rely on a single image. Request close-ups of the bell housing, output shaft, serial number tag, and any potential damage. Ask for a video of the input shaft being spun to listen for bearing noise.
- Inquire About Previous Vehicle: Knowing what Jeep the transmission came from can help verify its original application and potential condition.
- Check for Fluid Condition: If possible, see if there’s any fluid in the transmission and check its color and smell. Burnt fluid indicates excessive heat or wear.
- Verify Serial Numbers: Use any visible serial numbers or tags to cross-reference the transmission’s exact specifications.
- Consider a Pre-Purchase Inspection: If buying locally from a shop, ask if a third-party mechanic can inspect it.
- Budget for Associated Parts: Remember that you’ll likely need a new clutch kit, pilot bearing, throwout bearing, transmission mount, and possibly new U-joints or driveshaft work during installation.
Installation and Maintenance
Once you’ve secured your T5, proper installation and ongoing maintenance are key to its longevity.
- Professional vs. DIY: While a T5 swap is a common DIY project for experienced mechanics, it requires specific tools (transmission jack, proper torque wrenches) and knowledge. If unsure, professional installation is recommended.
- Associated Parts: Always replace the clutch, pressure plate, pilot bearing, and throwout bearing during a transmission swap. Inspect the transmission cross member and mount for wear.
- Fluid Type: The T5 is particular about its fluid. Most T5s require a specific manual transmission fluid (often 75W-90 GL-4 or specified synthetic). Never use GL-5 gear oil in a T5 unless specifically stated, as its additives can corrode the "yellow metal" (brass/bronze) synchros. Check your factory service manual or reputable Jeep forums for the exact specification.
- Break-in Period: For rebuilt units, follow the rebuilder’s recommendations for a break-in period before heavy use.
- Common Issues: Be aware of common T5 issues like weak 5th gear (especially under heavy load), worn synchros (leading to grinding shifts), and noisy bearings. Regular fluid changes can help mitigate wear.
