When most people think of transmission repair, a couple words come to mind: Rebuild and Overhaul. These terms are used quite often, and can lead to a lot of confusion for customers who may not be familiar with what actually happens, or what the terms mean. Overhaul and rebuild, at least in terms of transmission repair, actually mean the same thing. Now, let’s delve in a little bit to what that process entails.
First, we want to remind you that not every transmission problem requires a full rebuild. Many times, we can replace one or two components and get everything working again without even removing the transmission from the car. We may replace a sensor, or a solenoid block, or a valve body and get you going again for less than a rebuild or replacement.
Now, if your transmission does need extensive internal repair, a rebuild is the most common option. When we rebuild, or overhaul your transmission, we are taking the transmission that is in your vehicle now, repairing any damage, and refreshing any of the parts that wear out. Think of it like remodeling a house. We keep what’s good, replace what’s bad, and update things that could be improved. By keeping what is good, we save you money over replacing the whole thing.
When we rebuild transmissions, we remove it from the car, and our rebuilders dismantle the transmission and carefully inspect every part for damage or wear. We automatically replace what we call “soft parts.” Soft parts are things like gaskets, seals, and clips that can only be used once.
Soft parts also include replacing all the friction materials that make up the clutch packs in the transmission. For each gear, there is a series of friction plates, similar to a heavy duty board with a friction surface like sandpaper. These plates sandwich between steel components allowing the car to shift gears. By nature of how they function, the eventually wear out, just like your brake pads. We replace these every time, and in some cases, upgrade them to a stronger or more durable material.
Steel components, such as the planetary gears, the shafts that the gears ride on, bearings, and hydraulic components, are often referred to as “hard parts.” Hard parts aren’t designed to wear, and most of the time will outlast the life of the vehicle. We save, clean, and reuse any hard part that is still in great shape, which saves you money. If any of these hard parts has failed, we replace it.
Many transmissions have certain parts with flawed designs, or highly documented failures. In most cases, new parts have been designed to correct this flaw, so we will replace these components with the new updated part, even if the old one hasn’t broken. We do this to make sure you won’t have any more problems in the future. If you have a truck or van that does a lot of towing or hard work, ask us how we can upgrade certain components to be heavier duty. We can make your vehicle work harder and last longer.
As the cherry on top of every Cincinnati Transmission Specialists, Inc. rebuilt transmission, we inspect and test all the electrical components, and replace anything not up to snuff. Before we reinstall the transmission, we slide in a new or remanufactured torque converter, which is the link between the engine and transmission, and fill it up with fresh fluid. Then, we take the vehicle for multiple test drives to make 110% sure everything is perfect before we hand you the keys. When you drive away, you have a stronger-than-new transmission backed by the C-Guarantee Warranty to give you peace of mind.
