Transmission Repair Options

There are several options when it comes to automatic transmission repair. Your choice depends on factors like cost, quality and how long it takes you to get your car back. Here are the options:


New transmissions are not available from the dealer or any other source; they are only used in the production of new cars and trucks. When you purchase a transmission from the dealer you are getting one that is remanufactured. This is an important consideration when looking at the cost of the transmission.


A rebuilt transmission is one where the transmission is disassembled and inspected, worn or damaged parts are replaced (generally referred to as “hard parts”) and then reassembled to factory specifications, along with new gaskets, seals, clutches and bands. These are commonly referred to as “soft parts”. The term “rebuilt” is generally used in a shop setting where the customer’s transmission is removed from the car, rebuilt and then reinstalled. It is a custom process performed by a specialist. Another term you may hear that has the same meaning is “overhauled”.


A remanufactured transmission (commonly referred to as a “reman”) is similar to a rebuilt transmission, except the work is done in a factory setting. There are many common practices used in remanufacturing. One uses a team of workers skilled in a specific area of the repair. One person does the teardown and inspection, one person does the cleaning, several people will assemble and restore certain components and a final person will assemble the transmission.

Another uses a single person skilled at rebuilding a specific transmission or family of transmissions. There’ll be a Ford specialist, a GM specialist, a Chrysler specialist and so on. In this instance, they’ll rebuild an entire transmission from start to finish. In both instances the transmission is then tested on a dynamometer and then shipped to a retail outlet for sale (including dealerships).


A repaired transmission is one where a specific component is replaced or fixed. For example, if an input shaft broke or a solenoid failed those parts can be replaced without rebuilding the entire transmission. This includes instances were a transmission may have a leak. During the inspection it’s learned that the internal components still have a lot of mileage left in them. In this case just the external seals would be replaced in order to resolve the leaking problem. Generally speaking, with a repair, only the component that is replaced would be warranted. This can be problematic in that you may spend a significant amount of money on a repair and later have something in the transmission fail that is unrelated to the repair. It’s cost effective but does have an element of risk.


Another possibility today is to have a used transmission installed. Used transmissions have become a viable option because insurance companies will often total a car simply because the airbags deployed from a relatively minor accident. The rest of the car may be in terrific condition, with very low mileage.

A used transmission may cost hundreds less than a rebuild but in most cases they come with a lesser warranty, so there is a trade-off.

Keep in mind that not every option may be practical for you. A lot depends on the type of car you have, the mileage, the type of failure, and more. Your local ATRA Member will be happy to diagnose your car’s problem, and discuss the transmission repair options that are available to you.

ATRA Minimum Rebuild Standards

Posted in Articles, Transmission Repair Published 10/24/2013

ASSOCIATION REBUILDING STANDARDS: no member or person or firm shall represent that any reprocessed automatic transmission has been “rebuilt, according to ATRA specifications:, unless such transmission has been reprocessed in the following manner; and members further agree to extend nationwide, inter-shop warranty coverage only on such transmissions as have been reprocessed in the following manner:

      1. All internal and external parts shall be dismantled and thoroughly cleaned and inspected, including the case and bell housing.
      2. The following parts shall be replaced with new, each time; all lined friction clutch plates; all gaskets and rubber parts; metal sealing rings as are used in rotating applications; disposable type filters.
      3. All bands as are used in dynamic applications shall be replaced with new or re-lined bands, each time.
      6. The valve body shall be thoroughly cleaned and inspected; all dirt and varnish and foreign substances removed; all non-serviceable parts replaced, and new gaskets installed where applicable.
      The torque converter shall be considered to be a part of the transmission; and any torque converter which is installed along with a rebuilt transmission shall be internally cleaned and inspected for wear; externally checked for leaks, cracks, weld failure and hub wear; and starter ring gear wear, where applicable. Any converter which is judged as not capable of delivering new converter performance and life shall be replaced with a new or rebuilt converter. Any converter which is installed along with a rebuilt transmission main body shall be guaranteed by the member along with the rest of the transmission.
      6. Any and all other impaired, defective, or substantially worn parts which are not mentioned above, but which would not be expected to deliver new part performance, shall be restored to a sound condition, or replaced with new, rebuilt, or unimpaired used parts.

Transmission Service Information

A service is part of your regular maintenance, just like an engine oil change or replacing the coolant in your radiator. Regular service can help you avoid costly repairs to your transmission. Generally, you should have your transmission serviced every 18,000 miles, or two years. Some manufactures recommend longer service intervals like 50,000 or 100,000 miles, however, these intervals may exceed any opportunity for you to identify problems early on so you can avoid minor problems turning into a major repair. Consider a transmission service as you would an engine oil change; part of a regular maintenance schedule.

Generally, a transmission service replaces about 1/3 to 1/2 of the fluid inside the transmission and is adequate for a regularly-maintained transmission. For more severe instances you may consider a transmission fluid exchange.

As members of ATRA, we pledge to ourselves and to each other to diagnose transmission problems for customers and for each other in an expert and honest manner, and to state that the removal of a transmission from a vehicle in correction of its problems is necessary, only when this is the case.

Differential Repair

We’re happy to help you with any differential repair problem you may be experiencing. Differential problems can create a lot of noise under the hood and may cause damage to other parts of the vehicle if left unchecked. Typically, differentials, axle shafts & bearings, and ring & pinion gears make noise if they fail. If you hear these noises, please let us know. Depending on the noises you hear, driving your car may cause problems. If you have any questions at all about your transmission, stop by or call us and we’ll help you!

Allen Automatic Transmission is the leading service and repair provider in La Crosse Wisconsin for your automotive differential service and repair needs. The differential is the final part of your vehicle’s drivetrain that is positioned between two wheels and attached to each wheel by an axle shaft. The differential enables your left and right wheels to rotate at different speeds when making turns.

Differential Diagnosis

If you believe there is a problem with the differential in your car or truck, bring it to our La Crosse transmission shop and let one of our professionally trained and certified technicians perform a complete differential diagnosis to determine what is causing your problem and what it is involved to get the problem fixed.

Differential Rebuild

Allen Automatic Transmission is a leader in La Crosse Wisconsin for complete automotive differential rebuilding & service. During the rebuilding of your differential, all parts are carefully cleaned, inspected and replaced if necessary with only the finest quality parts and components. During the installation of your rebuilt differential, special tools are used to ensure proper pre-load, gear mesh and backlash. After installation is complete, your rebuilt differential is thoroughly tested before we return your vehicle.

Common parts that fail in a differential are the bearings and bearing races, the ring and pinion gears and the internal pinion (spider) gears and pinion shaft (pin). This can be caused by common wear and tear & not servicing the gear lube frequently.

Differential Servicing

The gear lube in your vehicle’s differential plays a vital role in keeping the ring gear, pinion gears, and axle bearings lubricated and cooled. Our technicians recommend changing your differential gear lube every 25,000 miles. If you would like to schedule a differential gear lube change on our online appointment page click here.
