Here is a breakdown of our GMC transmission rebuild and replacement procedure.

Initial Diagnostic Check: Our process starts with an in-depth discussion to collect data on the transmission problems you have had with your GMC. Typical indicators we look into are gear slipping, odd sounds, and leaking liquids. Furthermore, we examine your vehicle’s maintenance record and past transmission fixes to identify potential issues that could affect the rebuilding or replacement procedure.

Pre-Service Inspection: Before diving into repairs, our technicians perform a comprehensive visual inspection of your GMC’s transmission system. We check the transmission fluid level and condition, inspect for leaks, and look for any visible physical damage. Using specialized diagnostic tools, we also scan for error codes linked to the transmission control module. This thorough inspection allows us to pinpoint existing problems and assess the overall health of the transmission system before proceeding with the rebuild or replacement.

Test Drive: We perform a test drive to further assess the transmission performance of your GMC. Throughout the road test, we evaluate the transmission’s reactions under different driving conditions, searching for signs such as gear slippage, sudden shifts, or delayed gear changes. This practical test aids in precisely pinpointing the problems and deciding whether a transmission rebuild or full replacement is necessary.

Transmission Removal Preparation: After the diagnostics are finished, we will prepare your GMC for transmission removal. The first step involves draining the transmission fluid and examining it for any evidence of contamination, like metal particles or a burnt smell, that may suggest internal harm. We use a hydraulic lift to elevate the vehicle for easy access to the transmission system.

Transmission Removal: Our team meticulously removes all parts connected to the gearbox, such as the driveshaft, shift linkage, and electrical connections. We utilize specific tools such as an engine support bar to maintain the engine’s stability during the transmission removal. Each step is carefully carried out to avoid harming the neighboring components while removing them.

Transmission Disassembly (For Rebuilds): If a rebuild is necessary for the transmission, we will fully take it apart and examine every internal part, like gears, clutches, bands, and bearings, for any signs of wear or damage. This thorough assessment enables us to identify which components require replacement. Each part is carefully scrubbed, oiled, and readied for reassembling to bring the transmission back to its best shape.

Component Replacement (For Rebuilds): Throughout the rebuilding process, we replace the worn or damaged parts with either new or good quality reconditioned parts. Some are clutch, band, seal, gasket, and bearing. After removing the required components we replace them with new ones and then reassemble the transmission according to the guidelines of the manufacturer.

Install Rebuilt or Replacement Transmission: Our technicians will properly install either a remanufactured or new transmission in your GMC car. All electrical connections are made, the driveshaft and related components are reconnected, and every bolt is properly tightened.

Hydraulic System Bleeding: As we install, we evacuate the hydraulic system to remove any air that may have entered it while removing or installing the transmission. It is important to correct hydraulic pressure to enable efficient gear changing on your GMC.
