Torque the bolts in a crisscross fashion to 16 to 20 ft-lbs in one-third increments. Staggering the gaps helps the sealing rings hold pressure. Rock these assemblies back and forth until the forward clutch is completely seated in the reverse clutch drum. Attachment bolts receive 80 to 100 in-lbs not ft-lbs. One piece forged front cover prevents ballooning. Needless to say, learn from my mistake.
With our advanced shift firmness selection and exclusive torque compensation, it is now possible to properly calibrate the transmission for the increased demands created by supercharging, turbocharging, increased displacement, and similar modifications without destroying the transmission's street manners and daily drivability. Step 12: Assemble Pump Halves Make sure all holes line up, then mate and secure the pump halves. Take note of where all the check balls and other small parts are located arrows. Most of the fluid is contained in the torque convertor. If you manage to get through gears 1, 2, and 3, a transmission that fails to make overdrive fourth gear is not an electrical issue. And Ford was no exception.
This is why sometimes kit manufacturers want to know your vehicle identification number or build date when you order the kit. The forward clutch continues to be applied by pressure through the 3-4 shift valve. Go easy on it the first couple of minutes and let the fluid reach normal operating temperature. It is recommended that you lube the thrust bearing with transmission assembly lube for a good wet start-up. I suggest everyone with a 4R70W read that. Gas wars were common, with fuel at giveaway prices.
This filter is designed to trap contaminants and keep them out of the valve body passages and valve assemblies. The harness protects the wiring. There are also two one-way clutches, and four friction clutches. Step 7: Remove Main Pressure Booster and Regulator Valves Remove the main pressure booster and regulator valve assembly and lay these parts out on your work surface. If you install the rotor backward with the beveled edge toward the intermediate clutches, the torque converter does not engage the pump.
They are recommended for most performance engines that may see street usage. Take pictures of these valves as they came out of the valve body. As a result, Ford engineers added a spring to give the 3-4 shift valve a helping hand. I did not know about the J-Mod, and am investigating it further now, very intriguing. The counterweight is not shown, but it houses the valve assembly and counter-weights the complete assembly. The one lone solenoid C is for converter lockup in overdrive. Step 3: Remove Overdrive Servo Regulator Valve Remove the overdrive regulator valve and lay it out in the order it was installed.
Weak or soft engagement in any gear indicates insufficient line pressure from the source or leakage at clutch pistons or band servos. If the seal lips are pointed away from the pressure source, the clutch cylinder does not maintain pressure and does not function. Step 2: Remove Shift Valve Assembly Critical Inspection Remove the shift valve assembly. It is a blue spring. Adjust clearance via the clutch plates, which are. Step 8: Remove Valve Body with Separator Plate Once the separator plate is removed, examine the valve body passages and take a picture before disassembly begins. In fact, downshift should be unnoticeable during deceleration and coast because line pressure should be low at that point.
We accept no responsibility for any expenses or damages resulting from the purchase, installation and use of our products. I started by draining the transmission fluid and removing the pan and filter. Then re-torque them for a final check. The J-Mod instructions begin on page 12. Step 16: Compare Main Case and Pump Passages There is only one way to install the front pump. Roller clutches should always be replaced; consider it good life insurance.
This application has a Lokar aftermarket external linkage for column shift. Torque pin nuts with 13-mm heads to 140 to 160 in-lbs of torque. If you get a harsh 2-3 upshift, the problem is likely the 2-3 accumulator or excessive line pressure. Double-check the security of the band at the servo and anchor pins. The 2-3 shift valve moves under pressure against spring pressure.
Begin with a plate and alternately stack clutch discs and plates. Step 6: Install Clutch Piston Special Tool Use a seal protection tool to install the intermediate clutch piston installation. For 1996-up, use this orange spring. I disconnected the electronics, and then removed the 25 8mm bolts that hold the valve body to the trans body. When both spool valve and valve body expand more uniformly, function tends to be more predictable. Is the noise or vibration in rhythm with the engine, driveline, or wheels? Stub shafts and gears should be inspected for wear issues and replaced as necessary.
Internal Components Installation Step 1: Install Low-Reverse Band The output shaft and ring gear assembly have been installed along with the planet carrier. Lay everything out as it came out of the valve body and take detailed pictures. If you do get one, get a reverse manual, makes it easier to shift especially when racing. A clutch on the other hand, simply is along for the ride by connecting the engines power to drive-line. Shift Accumulator Installation Step 1: Install 2-3 Shift Accumulator TransGo says if you have an aluminum piston and the hole in the small end is deeper than the large end you should use the blue spring. Step 7: Lift Off Separator Plate Carefully remove the separator plate, making sure you do not disturb any of the check balls and other small parts inside.
