gauge is usually in the green (a little past the little white reference line). During kickdown, the gauge goes to yellow for a few seconds, then goes almost to red, then back to normal. 200A dual voltage alternator with triple belts. Is this ok, or is something about to break?

According to the parts manual, the unit is considered an H13 (basic unit). The manual shows a 12447125/2520014092512, but only if kit 57K3498 is installed. How do you know if it is installed?, and what is the part number if it isn't installed? Looks like there are (2) types that it could...

Mud half way up the wheels. Aren't these supposed to be full time 4WD? Rear wheels spin, front ones....no. Truck is in NL, front wheels not moving. BTW, what kind of company do you call to get you unstuck from a mud bog?

Looking for replacement batteries for my M998. It currently has the Walmart Maxx 34 series installed. Trying to avoid the 6TL's I see that Deka has an interesting deep cycle marine battery at 800 CCAs. It is about 1.5 inches taller and 2.25 wider. Or should I just stay with the Walmarts?

Is there an adjustment on the stop light switch? Having to push really hard in order for the brake lights to come on.

It is a 1993/1994 M998 with a 3L80 trans that will not shift into any gear. It used to sometimes take a minute after start up to shift, now it does not go into any gear at all. Almost felt like it had to build up pressure or vacuum when first started. Fluid is a pretty pink, no leaks...

starter is having an engaging problem and the engine will not turn over. Mechanic says he is having trouble finding starter shims (truck is a 1993/1994). Where can I go to find starter shims? Is there any civvy shims that will work?

When you step on the gas and the tdm valve engages the fan clutch, is it supposed to disengage the fan clutch after 20 seconds or so? If I get mine to kick on from mashing the gas pedal, it stays on. Truck runs at constant 187 degrees while on. Do you have to do something to "turn off" the TDM.

My unit came with just the blank rear door panels. Are the panels that have the hinges custom made? Or is there a part number for the ones with the hinges to access the compartment?

where would I happen to find the in-line fuel filter? The picture in the manual looks like it is behind the air filter? Is that true?

2 things here. Should normal LEDs for the 623 and 1683 bulbs work in the rear tail lights without any issues? My 1994 M998 has aluminum rear housings. There are places for 4 bulbs. Only the top 2 bulbs are installed in mine (623/1683). What are the 2 bottom bulb sockets for? What...
