This ensures that when your part arrives, it will have been rigorously tested for noises, leaks, vibrations and performance. Inspect it closely for wear and damage. This unusual system can accommodate up to 450 hp or so before pieces start snapping. Inspect the teeth for scoring and any damage that can hinder clutch friction movement. Cleanliness is never more important than with automatic transmissions. Even the background din of shop equipment, electric motors, gear and belt drives, air compressors, and the like will damage hearing over time.
Before disassembling the linkages, take pictures and notes. However, most are failure related. Most transmission professionals have indicated that fresh fluid tends to shock old seals, leading to pressure loss and failure. Magnetic parts trays are also a good idea. Step 9: Examine Low-Reverse Drum This is the low-reverse drum in a disassembled state, revealing the wavy Belleville spring inside the clutch drum, which releases this clutch pack. Look for atypical wear patterns, such as shiny spots and nicks that can snag clutches. Each clutch drum has an apply piston, which engages the clutches and steels.
Step 10: Disassemble Forward Clutch Disassemble the forward clutch, including the Torrington bearing and clutch hub. At home, you need to have completely drained the transmission or you will have a huge mess. With the valve body removed, you have access to servo pistons, the accumulator, manual and throttle valve linkages, and the parking pawl. If you are trying to find Ford Aod Transmission Rebuild Cost article fails to dwell right here, you can see from several of the articles that may suit your research. Never use a torque wrench to loosen fasteners. Step 8: Disconnect Flexplate and Torque Converter Remove the flexplate locknuts to free up the transmission and torque converter. Use goggles or safety glasses to protect your eyes from flying debris.
This means you don't have to compromise between streetability and performance. Stand mobility makes light work of transmission assembly because you can move it around as needed. Before 1991, expect to see a Motorcraft light-duty starter. Clutch friction discs and steels must mate with precision smoothness. Yeah, that's what scared me from buying a nice 88 5. Because automatic transmissions have dozens of tiny parts, organization is very important. Scoring can be honed out of the bore.
Eye protection is of utmost importance. Internal Components Removal and Inspection Step 1: Pull Forward Rotating Assembly With the pump removed, the input shaft, intermediate clutch, one-way clutch, reverse clutch, and forward clutch come out as an assembly. Buyers warranty begins at original date of purchase and expires 3 years or 36 thousand miles thereafter. Always recycle old, dirty fluid responsibly. Patc ford transmissions, c6, aod, 4r70w, 4r100, 5r110w , Patc ford performance transmissions, c4, c6, aod, 4r70w, e4od, 4r100, 5r110w, 6r80 and others.
Inspection The final process before shipment is a complete inspection of the entire unit. Tailshaft, Servos and Pistons Removal Step1: Remove Tailshaft Housing When removing the tailshaft housing pay attention to the seal and bushing condition. This could be a loss of line pressure from a worn seal, a sticking pressure relief valve, or dirty fluid, any of which may explain why clutches and bands burned up. When you split the pump for a look inside, be sure to note how the inner and outer pump gears are configured and carefully remove them for inspection. The normal pattern of failure is seal wear or damage, which leads to loss of hydraulic pressure and clutch and band slip-page. The governor controls are based on output shaft speed, which controls line pressure. Petroleum-based solvents are a good choice because they minimize the risk of rust and corrosion and make excellent grease cutters.
Restocking and shipping fees are applied if a customer wants to return a non defective transmission or is outside the continental United States. Dust masks are not sufficient protection. Because you want a clean job with a minimum of fuss, drain all fluids from the transmission sump and torque converter. Soft Parts Replacement Step 1: Perform a Thorough Cleaning All transmission hard parts go into a parts washer. Seals, especially, are easy to overlook when they must be replaced.
Tsb 1989 ford truck 350 4wd pickup v8-460 7. For items such as the main transmission case, tailshaft housing, and bellhousing, dishwashing detergent and a high-pressure washer work very well. Use air tools for disassembly, but never use them for assembly. Replacement is suggested in any case. Also inspect the pump cavity walls for scoring. A slide caliper is necessary to measure steels and frictions. But count on needing one to get the pump out.
When doing this, turn the clutch drum down, away from your face, and pop the piston toward the workbench and a soft towel to prevent damage. Working with this transmission is relatively simple because it has a mechanically activated throttle valve and torque converter lock-up located within the transmission case. All it takes is a tiny grain of sand to cause a valve to stick or a seal to tear. Teardown is an opportunity to learn why transmission failure, if any, occurred. The heat shield is there to keep extreme catalytic converter heat away. In general, not enough attention is paid to regular preventative maintenance: fluid and filter changes.
