Whether you're rebuilding for standard use or performance [26], this video provides the knowledge and insights you need to tackle your 700R4 rebuild with confidence. • Get ready to master this classic transmission and enjoy smoother shifts and increased reliability for years to come! • 700R4 Transmission Rebuild Study Guide • Quiz • Instructions: Answer the following questions in 2-3 sentences. • 1. Why is it important to pay attention to the orientation of the case bushing during installation? • 2. What tool is used to remove and install bushings in the transmission? • 3. What is the purpose of the “Beast” sunshell? • 4. Why are stater bushings particularly important in a 700R4 transmission rebuild? • 5. How many seals are used in the lower reverse piston assembly? • 6. What is the purpose of the lip seal on the various clutch pistons? • 7. Why is it crucial to use assembly lube during the rebuild process? • 8. What tool is used to install the snap ring on the reverse drum? • 9. What is the recommended clearance for the 3-4 clutch pack, and why is it important? • 10. How can you identify if a pump gasket is intended for an 82-86 model or an 87 and up model with an auxiliary valve body? • Quiz Answer Key • The case bushing has varying thicknesses of material. Orienting the thickest portion towards the 6 o’clock position ensures proper support for the spinning gear train, reducing wear and tear. • A bushing driver, often sourced from Snap-on, is used to remove and install bushings without damaging the surrounding components. • The “Beast” sunshell is an upgraded component that offers increased strength and durability compared to the original sunshell, due to added material in key areas. • Stater bushings are crucial as they support the rotating components of the transmission. Worn stater bushings can lead to misalignment, noise, and premature transmission failure. • The lower reverse piston requires three seals: two square/lath-cut seals on the outer part of the piston and one on the inside. • The lip seals on the clutch pistons are designed to direct hydraulic fluid to the piston, ensuring proper engagement and disengagement of the clutch packs. • Assembly lube is critical for reducing friction during initial operation, preventing damage to seals, bushings, and other components until proper lubrication is established. • A clutch spring compressor is used to install the snap ring on the reverse drum by compressing the return spring, allowing for easier snap ring installation. • The recommended clearance for the 3-4 clutch pack is 60,000 to 80,000 of an inch. This clearance ensures proper fluid flow and clutch engagement, preventing premature wear and slippage. • The 87 and up pump gasket will have a notch and an extra hole to accommodate fluid flow from the vent. The 82-86 gasket lacks these features. • Essay Questions • 1. Discuss the challenges and benefits of using a combination of 700R4 and 4L60 parts during a transmission rebuild. • 2. Explain the importance of proper bushing installation and removal techniques, highlighting potential consequences of improper installation. • 3. Compare and contrast the differences between rebuilding a transmission for standard use versus a performance build, emphasizing specific component choices. • 4. Analyze the role of the governor in a 700R4 transmission, detailing its function, components, and the potential consequences of a malfunctioning governor. • 5. Critically evaluate the arguments presented regarding the use of load release springs in the 3-4 clutch pack, weighing the pros and cons of their inclusion. • #700R4 Transmission Rebuild Guide: The content focuses on providing a comprehensive guide for rebuilding a 700R4 transmission, covering steps from bushing replacement to clutch pack assembly and governor inspection. It emphasizes proper techniques, specialized tools, and key components like the Beast sunshell.
