Transmission Repair & Rebuild Kits

If your automatic transmission is slipping between gears, leaking or emits a burning smell, or if your manual transmission is becoming hard to shift, makes grinding noise, or pops out of gear, then a replacement transmission or complete transmission overhaul may be in order. If you choose to repair your existing transmission with one of our OE quality transmission rebuild kits, you can restore like-new performance. If you’re hunting down transmission parts able to withstand the rigors of added power, check out our full line that includes Performance Automatic Transmission Rebuild Kits. Manufactured by top companies that know what performance is all about, these parts are engineered specifically to handle real-world horsepower and torque.

If you’re thinking of replacing your transmission, you have three options, new, used or remanufactured. Brand new replacement transmissions are not available for all applications and those that are come with a substantial price tag. A used transmission is an economical alternative, but the maintenance and use history are unknown quantities. Even if one proves to initially perform properly, some portion of its lifespan was used up in the vehicle it was removed from, and who knows how it will function next week or next month. The warranty on a used transmission is usually expressed in a number of days, not months or years, and the warranty normally does not cover labor costs if the transmission proves defective and must be removed. A remanufactured transmission is a good choice, they are rebuilt to a high standard, tested and come with an extensive warranty, but that quality comes at a considerable price.

Remanufactured transmissions are convenient, but if you have the skill, the time, and the tools, with a rebuild kit you can rebuild the transmission you have for less cash. Besides saving money, when you do the job yourself you have complete control over the quality of the work. However, even if you farm the job out to a mechanic, because you’re supplying the kit, you’ll still have control over the work that is done and what is replaced. And if you have a collector car or suspect your vehicle may be collectible in the future, having the original, serial numbers matching transmission in the drivetrain may make your machine more valuable.

The content of a transmission repair or rebuild kit varies according to application, the needs of the transmission, and the goals of the transmission technician. The most inclusive kits are master rebuild kits. A typical master rebuild kit for a manual transmission includes new bearings, bushings, thrust washers, synchronizer blocking rings, sleeve springs and insert keys, and gaskets and seals. For an automatic transmission a master rebuild kit normally includes new steel and friction clutch plates and bands, bearings, bushings, seals, O-rings, gaskets, internal sealing rings and transmission filter.

Nevertheless, a master rebuild kit may contain more parts than you need, or you may want to repair a specific problem and only require certain parts for the job. For those jobs we offer a myriad of repair kits, which enable you to get just the parts that you need. For example, transmissions contain several shafts and the seal contact surfaces of these shafts can become worn and grooved over time. If a shaft is worn, merely replacing the seal won’t fix a leak. Instead of replacing an expensive component with this kind of damage, one that performs perfectly otherwise, we offer a variety of repair sleeves. The sleeve is thin yet strong and is a press fit installation over the shaft. When it’s in place the seal lip has a smooth surface to contact for proper lubricant retention.

Whether you want a comprehensive kit or only the minimum parts needed for a repair, a transmission rebuild kit or repair kit represents a significant value. Purchasing a kit is much more economical than buying parts separately, plus you have the confidence of knowing your rebuild will be successful because all parts have been engineered to work together. Transmission rebuild kits are also substantial time savers. Instead of having to hunt for parts or spend a lot of time looking up and ordering individual parts, you can get everything you need with one or just a few part numbers.
