    Looking for help with 4L80E transmission on an M1123 HMMWV

    Engine is definitely frozen. Kind of pissed off as the video from Govplanet showed them jumping it and cranking over fine even though it didn't start. Figured that would be a fairly easy fix (Glowplugs, Controller, etc..) I'm thinking they posted the video of a different HMMWV, mixed up on...

    Looking for help with 4L80E transmission on an M1123 HMMWV

    Thanks, I'll give that a try. M1097A2, Noticed with the dual voltage alternator (my M988 doesn't have it) that you have to remove the surpentine belt to actually get at the crank pulley so no place out front to get at it, didn't reallly look behind if for a place for an open end wrench but now I...

    Looking for help with 4L80E transmission on an M1123 HMMWV

    Sorry, but the engine seems to be froze up so I haven't tried the Eprom. I could try to plug it in and at least scan it for codes. GovPlanet in the auction ad supposedly showed the engine cranking over but not starting? What could have happened to it between them filming the video and my...

    Looking for help with 4L80E transmission on an M1123 HMMWV

    Got both the Turbo and non-Turbo Eproms for pretty cheap from Eastern Surplus and ordered the TCM above from Advance Autoparts. Going to take my new AGM Costcom batteries out to the HMMWV tommorrow and see if it cranks and starts. Need to repair one small cable.

    Looking for help with 4L80E transmission on an M1123 HMMWV

    I just put the Silicone on the outside of the pan by the bolt head. Definitely wouldn't put it on the inside of the pan. Put in 2qts of oil to cover the bottom of the pan as a test to see if it leaks or seeps. After 24 hrs it's dry but we'll give it a few more days. A few different higher...

    Looking for help with 4L80E transmission on an M1123 HMMWV

    Cleaned the pan real well, left the screw in but cut it shorter so it wouldn't hit the filter anymore. Piled with a hefty amount of Silicone on the outside of the pan. Going to shop for a OEM pan or one of the new baffled fancy ones if I can find it for a decent price and will swap it out on the...

    Looking for help with 4L80E transmission on an M1123 HMMWV

    It appears going the older style with the Eproms is a much cheaper way? I wonder if one or the other is more reliable, no reason today why each shouldn't last the life of a vehicle like in a commercial vehicle? On another 4l80e question. Have any of you seen a HMMWV 4l80e with a Self threading...

    Looking for help with 4L80E transmission on an M1123 HMMWV

    Thanks. Somebody posted the shift points only change by about 500 rpms, doesn't sound like much but when you're talking about a Diesel that doesn't rev too high anyway 500rpm's can be quite a bit. Side thought. I just read about some of the later HMMWV's having Anti-lock brakes. I didn't know...

    Looking for help with 4L80E transmission on an M1123 HMMWV

    I see on the newer TCM's it lists the parts as TCM-2100AB/AC/BB/etc.... I don't see in the manuals any listing of what those TCM part #'s mean? The TCM I have still list the different Eprom's. Is there a updated pub which lists which TCM is for which vehicle? I've got a non-armored M1097A2. I'm...

    I do have a garage/shop but I don't remember them asking if I did, they might have.
