All, this was a question I had asked a while back and a member was kind enough to provide me his instructions he had floating around, but they were limited and suffered from the reprint-of-a-reprint syndrome. While browing some TMs for equipment I probably will never own (GRC-240), I just...

I need some help on this one. I had sent in my front/rear propeller shafts for modification after carefully measuring how much they needed to be altered in order to adjust for the 4L80E transmission. I had given them simple instructions to shorten one shaft and lengthen the other, but made the...

I just did a quick & dirty review of the MSD-ICE test kit on eBay and it got me thinking about things I could test using the digital DPA device. Obviously, there's the GM UART connector to test the 4L80E TCM, but I also realized the the S3 control box has a SAE J1939 connector, which that kit...

So, I'm curious how the banner ads are selected for this site. Obviously the side banner and very top of the page are direct sponsor ads, but the rotating ads between the breadcrumb links and the actual forum topics is what confounds me. Half the time, it's stuff that's obvious based on my...

I'm in the parts manual right now and I've noticed this notation in two separate wiring diagrams... It looks like the wiring diagram shows the TCM having a constant 12V feed through the circuit breaker, before the relay. The transmission itself isn't powered on until the relay is closed by...

I was looking at grabbing one of these, but wanted to know before I committed the money...has anyone gotten the ICE kit adapter set to work on a non-Miltope computer? The kits seem to have a basic software included with them, plus I have the HMMWV IETM that begs me to plug in an ICE Box...

I was putting the linkages together for my NP242 and made the discovery that I apparently can only shift from H to HL and back. If it try to shift it farther into N (and L), it just won't go. I can feel a vague attempt at it moving, but it feels almost like metal flexing at the shift tab and...

Alright, so I had this described to me once before, but I'm not seeing one on my block, nor have I found a picture of one online or in a manual to know exactly what I'm looking for. If anyone could help me locate a drain line location for the engine valley, I'd greatly appreciate it. I'm real...

So I first saw these in one of the army intructional videos, but later did some digging on ebay and saw a few of these for sale: Anybody have a part number for these, or perhaps an MWO to modify a standard fixed door to this? If I had to guess on how it's assembled, it looks like they've...

I'm looking to make use of some older amateur radio tech... Once upon a time, before cell phones, I've heard (not really old enough to have used these) that telephone system patches were commonplace, allowing you to use an HF or VHF transceiver to communicate with another VHF/HF transceiver...

So I've dug through the TMs and it feels like I'm just overlooking something...I can't find a TM that actually walks through the procedure for removal and installation of the transfer case and the transmission (but did find a section that covers the adapter between the two). While I've got the...

In case anyone wants to take a crack at my HMMWV, here goes! I picked this 1994 M998A1 off of GP. Their original stated location was Crane NSWC, but ultimately it was located on the SW side of Indianapolis on a private holding yard. Inside, I found paperwork indicating that it was in custody...

Feels like a dumb question, but I'm not 100% sure on this one so I needed to ask it. I picked up a MFY-6714UT starter, NSN 2920-01-507-7423. It's unfortunately a bit different than the MFY-6701 units that are detailed in the TMs I have. The wiring of the actual starter motor itself was...

My new HMMWV has a Luverne guard and the proper mounting brackets installed as well; however, I haven't managed to scavenge up the bolts, nuts, keeper pins, or rubber bumpers for it in all the scattered parts I have. Does anybody know the specs of the bolts and pins or a good source of a cheap...

Hey all, I know my A1 is going to be coming in with a weaker 60 Amp unit and it looks like it's missing parts, so I'm shopping alternators at the moment just in case it's truly DOA. I know that the 200 Amp dual voltage alt is the defacto go-to on these boards. It looks likes it's relatively...

So I've already pulled together most of the major, big dollar components I need for my 4L80E Install (I'm not exactly calling it a swap, since my M998A1 doesn't have any transmission...); however, I'm still missing the most important component of them all: the transmission. I've been reading...

Yesterday, I nailed the winning bid on my first MV, a 1994, 2-dr, M998A1 with a 6.5L NA engine. It's missing a transmission, transfer case (a new AMG 242 was hiding in the back!), rear drive shaft (hiding in back!), light switch, and the doors​ (hiding in back!). Most everything else looks...

I appreciate any help anyone can offer on this one. I've been lurking around for quite a while lookign into a few more modern MVs and due to the crossover of hobbies in amateur radio, I was hoping someone could help me get started in finding a military radio that might fit my needs (even if...
