Valve Body Inspection
1. If a line-to-lube hole has been drilled in the PR valve circuit, it should be plugged to reduce converter drainback.
2. Inspect the line pressure plug and sleeve. Leakage here will result in poor line pressure control.
3. Inspect the TV checkball separator plate seat. Leakage here may produce stacked shifts and/or no kickdown.

Disassembly Instructions
1. Remove the detent assembly and spring retainer bracket (see Figure 1).
2. Remove the original pressure regulator spring and valve.
3. Remove the end plate on the opposite side of the bore and remove the line pressure plug and sleeve, throttle pressure plug and the spring (see Figure 3).
4. Keep all components removed in steps 2 and 3 except for the pressure regulator valve, spring and the throttle pressure plug for reassembly.
5. Clean the bore.

Chrysler, one of the most dominant names during the early “Muscle Car” era, developed three basic series of engines which are still very popular in racing and performance today. Recently, the engineers at Chrysler added two versions of a new V-10. Both have become very popular. For our purposes we will refer to the 273-360 Small Block Chrysler engines as the “A” engine, the 383-440 Big Block standard head engines as the “B” engine, and don’t forget the ever popular Hemi. In these pages we have attempted to pass along some common “tips” learned during our many years of engine building, as well as the experiences of many of our customers. We will not attempt to cover all of the little things, only the more unique and aggravating trouble spots. If ever in doubt, there are many excellent reference manuals. (Mopar Performance) is one of the best. It goes into great detail about Chrysler engines.

If the complete throttle valve control module is current-less (e.g. connector disconnected) the throttle valve moves into a particular, specified mechanical position, which signals an increased idle speed with an engine at operating temperature. If only the Throttle Position (TP) actuator -V60- is current-less, the throttle valve also moves into the specified mechanical position (emergency running gap), however, since Closed Throttle Position (CTP) switch -F60- can still be recognized, an “almost normal” is reached via the respective ignition angle retardation. If the Engine Control Module (ECM) detects a malfunction at Throttle Position (TP) sensor -G69-, Throttle Position (TP) actuator -V60- is switched current-less by the Engine Control Module (ECM) and the throttle valve moves into the specified mechanical position (emergency running gap) again.

Ratcheting End Plug Removal:
Note: Prior to removing the ratcheting end plug from the bore, measure and note how deeply it is installed. The replacement plug should be installed to this same depth to ensure proper line pressure control. The most accurate method is to insert a slide caliper rod through the hole in the plastic plug until it bottoms against the control valve. Bring the caliper end toward the plug until flush. This gives you the spring height adjustment from the plug to the valve. Record this measurement before removing the plug and duplicate this distance during reassembly to most accurately duplicate the spring compression setting. If your caliper will not pass through the hole, measure from the valve body casting surface to the outer face of the OEM plug and duplicate later.

This kit will allow you to adapt a Chrysler 392 Hemi engine to all GM transmissions utilizing the Chevrolet bolt pattern. The use of this adapter kit will require a stock length torque converter. (A GM torque converter must be used with this adapter kit. It will not work with a Chrysler torque converter). Your Chrysler starter will bolt into place without any modifications. Reuse your OEM starter bolts.

Disassembly
1. Thoroughly clean and air dry valve bodies. Remove check balls. Remove each valve train.
2. Lay valves, springs and bushings on a clean surface in the order removed. Remove solenoids, sensor, screens, servos and accumulator assemblies.
Cleaning & Inspection
Clean valves, springs and bushings in solvent. NEVER use shop rags to clean valve body components. Inspect valves and bushings for scoring, nicks and scratches. Inspect springs for damaged or distorted coils. Inspect valve body casting for porosity, interconnected oil passages and damaged machined surfaces.

In 1993 Chrysler has improved security in their Double-Bitted locking system. All 1993 vehicles will utilize a new key groove (78 primary, 79 vallet), the change in key groove will initiate a keyway restricted vallet system and new J-Series codes. A seventh tumbler has been added to the ignitions.

To continue giving your customers the quality service their use to, the following should be noted when servicing the 1993 vehicles:
• Some new component parts have been added to the line, old component parts remain unchanged. (Tumblers, Caps, Shutters, Springs, Pawls, Shafts)
• New lock service packages will be required for 1993.
