My HMMWV is stuck in the safety mode (2nd gear). Did you have to disconnect the glow plug controller box as it states on page 60 of the manual? Thank you!
@@mtvrchannel3051 Thank you sir. I ended up getting it to work. I followed chart A1 and was able to get it to shift. Thank you sir. Keep up the good videos!
@@btrev5183 Mine is doing what yours is. Did you get it fixed? If so how did you do that. I’ve been fiddling whit mine so long I’m about to sell. This thing is just a pain in the butt.
I have a Humvee that may have a similar issue. I have the M1152 6.5 L Diesel. The brake switch is the same as what you have. The vehicle will go into over rev and struggle to maintain 40MPH. The engine is fine.
I just bought a 4 speed truck from auction. Missing the front right axle. The truck will move if transfercase is in HL and L but will not move in H. If I tap the brake while case is in H and trans in Overdrive it tries to engage but doesn't. All the fluids are good. I'm new to this, your experience would be greatly appreciated.
I’m having a 38 code, and tested the switch as you did with my multi meter, but I’m not sure what it should read to be a good switch. My transmission is stuck in limp mode (1st). What should the resistance be?
My torque converter locks in and out while driving between 50-65 mph over and over. It’s a 2008 m1123 4 speed. Any idea? I can send a video to a email if needed
Not yet. I unplugged the two prong connector while driving locking the torque converter in place and the problem stopped. You stated there is a process to adjust the brake module sensor if it’s out of alignment. Do you have a link on how to do that?
Sir, I have just aquired a 1988 AM General M1097A2. I followed your video and it gave me code 73. The issue im having with it is that it will not go in reverse. If there is any advice you can give me I'd be very grateful. I can not find what 73 is.
Check my “pinned comment” at the top of these comments, open the link in it, and go to code 73, you probably don’t have 4th gear either. The manual you’ll see will have an entire guide for diagnostics
My M1097A2 4 speed is in limp mode and stuck in second gear. Will shift into neutral and reverse, but goes and stays in 2nd once I put it to drive or overdrive. Help me brother!...lol
It all starts with my comment pinned at the top of comments, go in that guide and pull your codes. There’s a step by step all inclusive guide inside that manual
Sorry, fat fingers,….. but the tranny won’t shift out of first gear. What should I do? Does the fact that I have no break lights working mean ghat The dual break lights switch in your video is the culprit?
connecting jumper cable pin A and E of the J2 TCM connector. trany flash light : *_*_*____*_*_*____*_*_*____********(8)_*___********(8)_*___********(8)_* . what does mean ?

@@btrev5183 I did not have to disconnect mine for diagnostic purposes

@@btrev5183 Can you please tell me what was your problem? I'm trying to get my working. Thank you.
Thanks for the video. I just picked up my 1993 AM General 998 with. 6.2 and a 4 speed. The engines is in truck suspension engine overall great shape
Amazing video!! Thank you for this guidance!!
Great video. I have learned alot

Great video. Trans light just stays off. Any idea? I saw you did not disconnected the Glow Plug Controller. Does that make a difference? Thank you.
great vid. Is this truck a serial under 29k or above? or does it not matter when using the jump cable on the tcm to find your codes,

Great video. You should have a video and a way to send you $ for your knowledge!! Put that link in the description.
Thanks!
Great video. Any chance you’d have a guess on late shifts and redlining at 62mph? I’m at 33-3400 at 62 so it’s like it’s not going into overdrive.
Are you locking and unlocking the tourqe converter by applying the breaks?
Will this break switch make the transmission not shift out of 1st gear ?
hi pls, great video. can u pls recommend the diagnostic OBD that can be used?
You don’t need one
I’m having a 38 code, and tested the switch as you did with my multi meter, but I’m not sure what it should read to be a good switch. My transmission is stuck in limp mode (1st). What should the resistance be?
Thanks for the video....anyone have any idea as to what would cause the TCM not to respond when jumping a&e? Trans light just stays lit
In my humvee, Trans light just stays off. Any idea? He did not disconnected the Glow Plug Controller. Does that make a difference? Thank you.
My Hmmwv is not shifting in overdrive . do you have any suggestions ?
What was the reading on the ohm meter? I heard the buzzer but can’t see the reading. Mine read .3 and then pressed down OL out of limits.
That’s what it should be. You’re looking for
@@mtvrchannel3051 Thank you I am lucky to hold .3 ohm when moving/brake not applied.
Nice Genny you got, before long you'll have your own Motor Pool 😂
I already feel overwhelmed 🤣
Thanks!

Have you pulled the codes yet?
Not yet. I unplugged the two prong connector while driving locking the torque converter in place and the problem stopped. You stated there is a process to adjust the brake module sensor if it’s out of alignment. Do you have a link on how to do that?
Hi, did you have an experience with new Oshkosh S-ATV ? is it match better and more reliable than Humvee ?
Unfortunately I don’t have any real world experience with them
How do you lock and unlock the torque converter? Is when you step on the brake?
I had a manual toggle for demonstration purposes in this but yes the brakes do it

Chances are, it’s stuck in 2nd gear limp mode. Pull your codes and see what you get
connecting jumper cable pin A and E of the J2 TCM connector.
trany flash light : *_*_*____*_*_*____*_*_*____********(8)_*___********(8)_*___********(8)_* .
what does mean ?
There’s a manual link in here
I’m getting the same code. 8 lights. Did you figure out what it means? Thanks.
