Using supplied hardware, re-attach the factory exhaust pipes to the headers and tighten bolts evenly to ensure a tight seal. ( Note: The 7/16 x 2 bolts are to be used on 4.8L, 5.3L, & some 6.0L V8s. The 7/16 x 1 ¾ are for the left side of 4.8L & 5.3L V8s, and on the 6.0L V8 that do not have OEdonut gaskets. 3. After the factory exhaust pipes have been tightened to the collector flange of the header, tighten the port flange bolts to recommended factoryspecifications. FINAL INSPECTION 1. Check all lines (hydraulic, vacuum, air conditioning and fuel) to ensure there is adequate clearance to headers. 2. Re-connect battery. 3. At this point, it is a good idea to look everything over and make sure that nothing was missed in assembly. 4. Start vehicle and bring up to normal operating temperature. Check for possible leaks. 5. Turn engine off and let cool. Tighten all bolts again. Note: Thick washers are to be used on slotted holes of port flange. 4. Re-install spark plug wires. Note: Due to production tolerance, it may be necessary to bend the motor mount heat shield for better clearance. ASSEMBLY OF EXHAUST PIPE Note: Some 2007 model year vehicles will have a donut gasket on the right side OE exhaust manifold. If your vehicle has that donut gasket, it will be re-used with your shorty headers (see below). This system comes with 2 exhaust crush rings. On 2001- 2006 4.8L & 5.3L V8s, one will be used on the left side collector. On 2001-2006 6.0L vehicles will use one on the left side and one on the right side to replace factory-installed crush rings. 1. On 4.8L, 5.3L, &6.0L V8s with donut gasket – Remove the donut gasket from right side exhaust manifold. Using a pair of pliers, remove the retaining ring from the donut gasket and place the donut gasket in flare of factory exhaust pipe.

46RE AUTOMATIC TRANSMISSION DIAGNOSIS AND TESTING – ROAD TESTING Before road testing, be sure the fluid level and control cable adjustments have been checked and adjusted if necessary. Verify that diagnostic trouble codes have been resolved.Observe engine performance during the road test. A poorly tuned engine will not allow accurate analysis of transmission operation. Operate the transmission in all gear ranges. Check for shift variations and engine flare, which indicates slippage. Note if shifts are harsh, spongy, delayed, early, or if part throttle downshifts are sensitive. Slippage indicated by engine flare, usually means clutch , band or overrunning clutch problems. If the condition is advanced, an overhaul will be necessary to restore normal operation. A slipping clutch or band can often be determined by comparing which internal units are applied in the various gear ranges. The Clutch and Band Application chart provides a basis for analyzing road test results. Note that the rear clutch is applied in all forward ranges (D, 2, 1). The transmission overrunning clutch is applied in first gear (D, 2 and 1 ranges) only. The rear band is applied in 1 and R range only. Note that the overdrive clutch is applied only in fourth gear and the overdrive direct clutch and overrunning clutch are applied in all ranges except fourth gear. For example: If slippage occurs in first gear in D and 2 range but not in 1 range, the transmission overrunning clutch is faulty. Similarly, if slippage occurs in any two forward gears, the rear clutch is slipping. Applying the same method of analysis, note that the front and rear clutches are applied simultaneously only in D range third and fourth gear . If the transmission slips in third gear, either the front clutch or the rear clutch is slipping. If the transmission slips in fourth gear but not in third gear, the overdrive clutch is slipping. By selecting another gear, which does not use these clutches, the slipping unit can be determined. For example, if the transmission also slips in Reverse, the front clutch is slipping. If the transmission does not slip in Reverse, the rear clutch is slipping. If slippage occurs during the 3-4 shift or only in fourth gear , the overdrive clutch is slipping. Similarly, if the direct clutch were to fail, the transmission would lose both reverse gear and overrun braking in 2 position (manual second gear). If the transmission will not shift to fourth gear , the control switch, overdrive solenoid or related wiring may also be the problem cause.
