The B means it is black, it will not be marked BT, only T etc.

It is there, but it could be a #29 with a different suffix, there are several #29s in that area and someone could have connected them differently, all the #29 wires should be switched 24V

Invest in a cheap set of gauges!! HF has them.

Probably not, in FL he is on high ground :ROFLMAO: :ROFLMAO: :ROFLMAO:

Dropping the trans would be allot easier than lifting the body. I would think dropping the trans would be easier than lifting the body.

Actually it does not look like the clamp nut has even been touched :)

You might want to inspect the connector at the trans for fluid in the connector. But the internal (transmission) harnesses also fail as could the valve solenoid.

There are two plugs on the TCM box, use the other one, the harness must be connected. Also by disconnecting that harness you have erased any stored codes.

You are stuck in limp mode as pointed out above, read the supplement about putting a jumper on the acc plug at the TCM and read the codes. I was confused as you were saying it shifted but would not go into OD EDIT it is on page 60. Here is the pinout of the acc connector you jump A to E simple...

Did it have a GVWR of 10K or more? I bought a M998 a couple years ago with a GVWR of 7700 and it was stamped off road.

So I ran across this web site. https://www.replacementlightbulbs.com/index.html And they have allot of rare bulbs at what I think are reasonable prices Example, (hmmwv but many are common to most MVs) 1683, dual fil, used as turn/stop .77ea 623. dual fil, used as tail etc .45ea 1251 dual fil...

IIRC the A2 trucks had a min GVWR of 10.300lb, all the 10K trucks should have 10K half shafts

Are you sure it is just not shifting into OD or are you saying it does not shift at all??

That is helpful, there are two different transmissions and three different gear ratios available in the HMMWV, I will let others comment on your request. You have a 4 speed and 3.07 gears

Welcome to the SS forums! A little more info is needed like just what are you talking about

You have to beat the 7K shafts apart, they are not put together with removable rings like the 10K or aftermarket half shafts have.

If the TCM is getting enough power that it is shifting then it is usually the lamp or the wires to the lamp. Wire number 675B should be hot with 12V all the time, the other grounds in the TCM to turn the light on. IIRC the "hot" (12V) is the contact in the harness plug that the light is plugged...

The first thing you need to is get that trans light working and see if there are any codes. So you do have the "transmission supplement"?

Am I missing something here? The OP asked about tire/wheel issues, many have gone to say 17" etc, we see it all the time here, I don't see why that would necessarily be an item for the hot rod/mods page and I don't see why the conversation had to go negative respectively or not.

The only ones I have seen lately are sub 10K trucks, both of the basic M998 trucks I bought had the off road stamp, all the 10K and higher trucks did not have the off road stamp. If it says "sells with clean SF-97" you should be good to go. (depending on YOUR states attitude toward the HMMWV)...
