**C6 Transmission Teardown Inspection: Diagnosing Burnt Clutches and Other Issues**

C-6 Transmission Teardown Inspection Analysis "C-6 Transmission Teardown Inspection - Transmission Repair" YouTube Video I. Introduction and Initial Disassembly Brief overview of the C-6 transmission from a Ford Bronco (circa 1988) and the goal of the teardown inspection. Removal of the 4x4 extension housing adapter and the governor, highlighting the governor's function and common failure mode (sticking valve). Detachment of the rear support, kickdown linkage, passing gear lever, and the neutral safety switch, explaining the purpose of each component. II. Pan Removal and Initial Assessment Removal of the transmission pan, revealing a significant amount of friction material, indicating burnt clutches. Removal of the valve body and identification of the deep pan design common to 4x4 models. Removal of the B adjuster, strut, band anchors, and second gear band, noting the hardened rubber and poor condition of the servo. III. Front Pump Assembly Disassembly and Inspection Disassembly of the front pump assembly, including the stator assembly, pump gears, and pump washer. Detailed examination of the stator assembly for wear patterns and grooves, highlighting the importance of a smooth surface for proper pump gear operation. Analysis of the pump gears for scratches, scoring, or damage, emphasizing their smooth condition in this case. Review of the pump washer and its role in adjusting input shaft endplay. IV. Clutch Drum and Planetary Gear Analysis Examination of the third and reverse clutch drum assembly, focusing on the condition of the sealing rings and their importance for proper sealing. Removal and evaluation of the clutch pack assembly, noting the color and condition of the friction and steel plates, along with the pressure plate. Identification of burnt forward clutches and a welded forward ring gear, indicating significant heat damage. Inspection of the forward clutch drum sealing ring surfaces for wear and the need for replacement. Evaluation of the second gear band, noting its burnt condition and cracking, indicative of age and wear. Examination of the forward planetary gear assembly, checking for excessive endplay and wear on the pinion. Review of the rear planetary gear assembly, applying the same endplay and wear checks as the forward assembly. V. Output Shaft and Low/Reverse Clutch System Inspection Analysis of the low and reverse clutch assembly, explaining its function in reverse gear and engine braking situations. Inspection of the output shaft and its three sealing rings, highlighting their role in governor oil feed. Evaluation of the output shaft support for wear and the importance of smooth sealing ring contact surfaces. Examination of the parking pawl assembly and its function in locking the output shaft. Detailed analysis of the low/reverse one-way clutch (sprag assembly) and the evidence of wear, emphasizing the importance of replacing worn bushings to prevent cascading damage. Removal and inspection of the low/reverse piston assembly. VI. Governor, Modulator, and Final Assessment Examination of the governor and modulator assembly, explaining their roles in transmission control. Discussion of the modulator valve and its function in controlling shift points based on vacuum and kickdown input. Final assessment of the transmission's overall condition, listing necessary replacement parts including bushings, overhaul kit, second gear band, steel plates, modulator, filter, and a shift correction kit. Emphasis on the age of the transmission and the benefits of a shift correction kit for improved performance and reliability. This is a C-6 unit of a 1988 Ford Bronco 4X4. This is a governor and modulator controlled transmission. Here we see the basics on what to look for when tearing down these units, or any unit, the principals are the same. basically we need to bring this unit back to factory specifications and install upgrades to keep it on the road where it belongs. In this case we are going to install a shift correction kit along with all the necessary parts to rebuild it. #C6Transmission #TransmissionTeardown #TransmissionRepair #BurntClutches #FordBronco #4x4 #AutomaticTransmission #TransmissionOverhaul #DIYTransmission #MechanicTips
