These sealing rings must be well lubricated for pump installation. Protect your eyes and face for this step. Work the sun gear drive shell back and forth to seat. Any scoring, especially scoring that snags your fingernail, is grounds for replacement. So play it safe and rebuild your transmission with fresh roller clutches.
If the converter clutch is causing the shudder, then the shudder will disappear once the converter clutch turns off. Installing them wet gives them a good start against freshly resurfaced clutch drums. Examine the check ball valves for freedom of movement. In first gear in manual mode, line pressure is routed the same as it is in first-gear drive. Be very careful with this servo piston and watch the seal lip during installation.
The 2-3 back-out valve, as the name implies, regulates the feel of a 2-3 upshift. Next you will need to loosen the nut inside the transmission that holds the shift lever shaft to the rooster comb the plate that has the detents for the gears, and the pin for the manual lever. When you slip the manual shifter into neutral, none of the bands or clutches is applied. Step 9: Install Forward Sun Gear Drive Shell The forward sun gear drive shell splines into the planet carrier and stub shaft. Does the engine stall when the transmission selector is placed in gear? Make sure you have plenty of lube and smooth piston travel. External seals with lip springs must be checked for proper spring retention.
We also offer an upgraded version of this shaft. Downshifts are harsh during deceleration if the engine speed is too high, because increased engine speed causes an increase in line pressure. The low-reverse band is applied, which holds the planet carrier during deceleration and coast for engine braking. Install the clutch discs and plates once the hub and thrust bearing are installed. Cages become damaged and at times this is even harder to see.
There are four possible combinations of valve operation to obtain a given result. Use plenty of lubrication as a pre-lube and for adhesion. Apply uniform pressure to the piston while feeling for a smooth transition. The next items to check are the number-3 and number-4 sealing rings. Locking out overdrive with the button does not help. Slowly walk the tool around, protecting the seal lip. Torque the gasket bolts to 107 to 132 in-lbs, not ft-lbs.
Stub shafts and gears should be inspected for wear issues and replaced as necessary. Step 3: Install Intermediate Clutch Piston Seals As you install the new intermediate clutch piston seals, keep in mind the seal lips must point toward the pressure source or inside the pump housing bore. The planet carrier splines inside the ring gear with gentle back-and-forth twisting to achieve proper engagement. Help us help you, and others. Step 7: Install Forward Sun Gear This is the forward sun gear stub shaft, which fits into the heart of the planet carrier. Remove the pan and inspect the filter. I do not have this information.
Did the problem arise after transmission service or part replacement? I checked the 1-2 accumulator springs and they were not broken, what else could be wrong? Step 12: Install Number-4 Thrust Needle Bearing The number-4 thrust needle bearing installs inside the forward sun gear drive shell. Torque the bolts in a strict pattern to prevent warping. Step 3: Install Manual Shift Linkage and Manual Valve The manual shift linkage and manual valve line up like this. You could have excessive slippage on your intermediate clutch pack, or a problem with your shift solenoids. This Tech Tip is From the Full Book,. This could be caused by a defective solenoid, wiring problem, or bad processor. This problem certainly isn't transmission related, but you could try the suggestions on.
But the real thing you need to worry about is excessive heat buildup. Begin your troubleshooting with electronics, then mechanicals. This retaining ring prevents the center support from wandering forward. Also a slipping clutch can make for a harsher shift when it does finally engage. Step 3: Install Reverse Clutch Piston Install the reverse clutch piston seals using generous amounts of transmission assembly lube. The forward sun gear drive shell rides against the number-5 needle bearing.
