DESCRIPTION
Radio noise suppression devices are installed on this vehicle. Radio Frequency Interference (RFI) and ElectroMagnetic Interference (EMI) can be produced by any on-board or external source of electromagnetic energy. These electromagnetic energy sources can radiate electromagnetic signals through the air, or conduct them through the vehicle electrical system.

When the audio system converts RFI or EMI to an audible acoustic wave form, it is referred to as radio noise. This undesirable radio noise is generally manifested in the form of “buzzing,” “hissing,” “popping,” “clicking,” “crackling,” and/or “whirring” sounds. In most cases, RFI and EMI radio noise can be suppressed using a combination of vehicle and component grounding, filtering and shielding techniques. This vehicle is equipped with radio noise suppression devices that were designed to minimize exposure to typical sources of RFI and EMI; thereby, minimizing radio noise complaints.

Radio noise suppression is accomplished primarily through circuitry or devices that are integral to the radios, audio power amplifiers and other on-board electrical components such as generators, wiper motors, blower motors, and fuel pumps that have been found to be potential sources of RFI or EMI. External radio noise suppression devices that are used on this vehicle to control RFI or EMI, and can be serviced, include the following:

Engine-to-bulkhead ground strap - This length of braided ground strap has an eyelet terminal connector crimped to each end. One end is secured to the engine cylinder heads. The other is secured to the bulkhead.
Resistor-type spark plugs - This type of spark plug has an internal resistor connected in series between the spark plug terminal and the center electrode to help reduce the production of electromagnetic radiation that can result in radio noise.
Exhaust-to-frame ground strap - This length of braided ground strap has an eyelet terminal connector crimped to each end. One end is secured to the exhaust pipe. The other is secured to the frame.

FLUID/FILTER SERVICE
NOTE: Only fluids of the type labeled Mopar® ATF+4, Automatic Transmission Fluid, should be used in the transmission sump. A filter change should be made at the time of the transmission oil change. The magnet (on the inside of the oil pan) should also be cleaned with a clean, dry cloth.

NOTE: If the transmission is disassembled for any reason, the fluid and filter should be changed.

Raise vehicle on a hoist. Place a drain container with a large opening, under transmission oil pan.
NOTE: One of the oil pan bolts (5) has a sealing patch applied from the factory. Separate this bolt for reuse.

Loosen pan bolts and tap the pan at one corner to break it loose allowing fluid to drain, then remove the oil pan.
Install a new filter and o-ring on bottom of the valve body and tighten retaining screws to 5 N·m (40 in. lbs.).
NOTE: Before installing the oil pan bolt (5) in the bolt hole located between the torque converter clutch on and U/D clutch pressure tap circuits(Pan Fastener), it will be necessary to replentish the sealing patch on the bolt using Mopar® Lock & Seal Adhesive.

Clean the oil pan and magnet. Reinstall pan using new Mopar® Silicone Adhesive sealant. Tighten oil pan bolts to 19 N·m (165 in. lbs.).
Pour four quarts of Mopar® ATF+4, Automatic Transmission Fluid, through the dipstick opening.
Start engine and allow to idle for at least one minute. Then, with parking and service brakes applied, move selector lever momentarily to each position, ending in the park or neutral position.
Check the transmission fluid level and add an appropriate amount to bring the transmission fluid level to 3mm (1/8 in.) below the lowest mark on the dipstick.
Recheck the fluid level after the transmission has reached normal operating temperature (180°F.).
To prevent dirt from entering transmission, make certain that dipstick is fully seated into the dipstick opening.

STANDARD PROCEDURE - FLUID DRAIN AND REFILL



1 - I.D. TAG
2 - FILL PLUG
3 - DRAIN PLUG



The fill (2)(Fill/Drain Plug and I.D. Tag Location - Typical) and drain (3) plugs are both in the rear case.

Raise vehicle.
Position drain pan under transfer case.
Remove drain and fill plugs and drain lubricant completely.
Install drain plug. Tighten plug to 20-34 N·m (15-25 ft. lbs.).
Remove drain pan.
Fill transfer case to bottom edge of fill plug opening with Mopar® ATF +4, Automatic Transmission fluid.
Install and tighten fill plug to 20-34 N·m (15-25 ft. lbs.).
Lower vehicle.

Interesting! I could have sworn my Infinity stereo had a sub in it with how potent the bass is. I guess I was wrong. Where did you find all this? I might have to get me a copy.

 

[copeland]

have a "inside" who is a mechanic at dodge, this is off the tech site for dodge, he was just emailing me a couple articles since it requires a login and he doesn't know how stringent the admin is. He's looking into a manual on cd for me...

 

[98DakotaSport]

Thanks for the info!

If anyone needs any other info, I "obtained" a FSM for the 05, so feel free to ask.

 

[copeland]

I envy you...must find a copy now that it's out...
