AUTOMATIC TRANSMISSION

Automatic transmissions are becoming increasingly more popular in the UK, with more of them on the road we are seeing an increase in these transmissions needing servicing and rebuilds. Fully automatic gearboxes come in many options from 4 speed even up to the most modern 10 speed fully automatic transmissions. Equipped with a torque converter the purpose of the transmission is increase comfort for the driver and perform smooth gear changes and improving fuel consumption.

At The Gearbox Centre in Kent we are advocates of prevention is better than cure. This comes in many formats, the first format is where possible service your transmission on a regular basis, this will increase the chances of avoiding a costly gearbox rebuild and will also improve the quality of your driving experience, the second is when rebuilding a transmission if there is a solution to reverse engineer a problem out of the transmission we will always do this to ensure that the issue does not happen again.

Automatic transmissions consist of a torque converter, gearset, valve body and mechatronic unit. All of these components make up what is a complex design, at The Gearbox Centre in Kent we have invested heavily in testing equipment to make sure we get it right first time before being installed into the vehicle, improving downtime and getting you back on the road as quickly as possible. We are also capable of sending units out to our trade customers safe in the knowledge they are going to perform as they should in the vehicle.

We repair and reconditioned all types of automatic gearboxes ranging from 4 speed gearboxes all the way up to the most modern 10 speed gearboxes. Feel free to give us a call today to find out how we can help 01795668080.

Valve body testing for automatic gearboxes is a critical process that ensures the smooth operation and reliability of your transmission systems. At The Gearbox Centre, we specialise in precision testing services that assess the performance and durability of valve bodies, which are essential components in automatic transmissions. Our advanced testing procedures include rigorous pressure testing, flow rate analysis, and functional evaluations to verify that each valve body meets industry standards and operates flawlessly under varying conditions. By ensuring optimal fluid control and seamless gear shifting, our testing services help prevent transmission failures, reduce maintenance costs, and extend the lifespan of your gearbox systems. Trust us to deliver accurate and dependable results that keep your automatic transmissions running at peak performance.

SOFTWARE

The Hydra-test in house developed software allow a us to run a series of tests to check the performance of a valve body at various gears and pressures for proper operation. Simply put, We can emulate transmission performance of the actual vehicle. Hydra-test have diligently written scripts for all supported valve bodies that the controller uses to perform a standard test sequence to the unit under test. By running a used valve body through a series of carefully written steps and recording the pressures, the system gives the us a graphical display of the unit under test compared to an original new valve body of the same model. This comparison makes it possible for us to determine the exact source of valve body problems – be it a damaged solenoid, a worn valve and bore, or plunger.  

Library of Reference Results

The vast experience of the Hydra-Test team collected over the years has allowed them to accumulate a large database of test results. Based on this, they have created an extensive library of reference results, which include tests for all of the common automatic transmission models available in the market today. This library allows us to successfully be able to test and qualify solenoids. We are given a vast library of good test samples and statistics for scrutiny for any unusual “non-standard” behaviour of tested solenoids. This significantly reduces the rejection of “suspicious” solenoids, giving us confidence in the results that are achieved.
