Expert Hummer Transmission Rebuild and Replacement

Our team at The Car Lab Auto Repair Center understands the role of the transmission of your Hummer in providing you with enhanced reliability, power, and durability. We have trained mechanics with the advanced equipment and skills to handle all transmission issues of your Hummer, whether you need a rebuild or a new transmission. From identifying the source of various issues in your car to delivering custom solutions, we ensure your vehicle is well-maintained. Here is a detailed guide to our extensive procedure for Hummer transmission rebuild and replacement:

Initial Diagnostic Check: It starts with a consultation, during which we get the details of any challenges you have faced with  your Hummer Transmission. It may involve slipping of gears, strange sounds or noises, or signs of leakage of fluids. In addition, we will look at your vehicle’s service history to determine any previous transmission work and check for any recurring issues. In this way, we can learn about the condition of your transmission and approach the service more effectively.

Pre-Service Inspection: Our technicians thoroughly examine the entire transmission system during any major repair. It involves checking on the fluids and their qualities, testing for any signs of leaks, and using a scan tool to seek any error codes concerning the TCM. It is essential in the process because it helps identify which part of the device is the exact problem and whether it has to be rebuilt or replaced entirely.

Test Drive: A test drive is a crucial step in diagnosing transmission issues. Our mechanics take your Hummer out for a drive under various conditions to evaluate how the transmission responds. We monitor gear shifts, slippage, shifting delays, and overall performance to gather critical data on the transmission’s operation. It allows us to understand the issues better and recommend the right action.

Transmission Removal Preparation: Once the diagnostics confirm that a rebuild or replacement is necessary, we prepare to remove the transmission. The vehicle is elevated using a hydraulic lift to access the transmission system. First, we empty the transmission fluid to check whether it contains metal deposits or has a burnt smell, indicating internal wear.

Transmission Removal: Our team then expertly detaches and unbolts all components linked to the transmission. Specific support tools ensure that the vehicle’s engine is firmly positioned while the transmission is unwired from other parts of the car. All bolts, connectors, and parts are handled carefully to ensure they are not damaged.

Transmission Disassembly (For Rebuilds): In case a rebuild is needed, our specialists will dismantle the transmission to evaluate each part separately. It involves inspecting gears, clutches, bands, seals, and bearings for signs of wear or damage. A thorough examination helps us identify the components that require fixing or replacing.

Component Replacement (For Rebuilds): In rebuilding, we swap out broken or old parts with new or reconditioned components. It generally involves clutches, seals, bands, gaskets, and bearings. Every component is carefully cleaned and oiled to guarantee a seamless performance and lasting strength. The transmission is back together after ensuring all parts are in perfect shape.

Install Rebuilt or Replacement Transmission: Our expert technicians put the transmission back into the vehicle. We meticulously reattached the driveshaft, shift linkage, electrical connections, and other removed parts. All the bolts and fasteners are correctly tightened, following the manufacturer’s recommendations to ensure a correct and safe installation.

Hydraulic system Bleeding: During the hydraulic system bleeding process, we remove any air bubbles that may have been formed when replacing the system. The amount of bleeding performed is essential to remove any surplus hydraulic pressure in the transmission system.
