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

Great video. I have learned alot

Amazing video!! Thank you for this guidance!!

great video thanks.

Well Done!

Thanks

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

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’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?

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.

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?

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,

Will this break switch make the transmission not shift out of 1st gear ?

Great video. You should have a video and a way to send you $ for your knowledge!! Put that link in the description.

My Hmmwv is not shifting in overdrive . do you have any suggestions ?

Hi, did you have an experience with new Oshkosh S-ATV ? is it match better and more reliable than Humvee ?

Nice Genny you got, before long you'll have your own Motor Pool 😂

hi pls, great video. can u pls recommend the diagnostic OBD that can be used?

How do you lock and unlock the torque converter? Is when you step on the brake?

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.

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.

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

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

connecting jumper cable pin A and E of the J2 TCM connector. trany flash light : *_*_*____*_*_*____*_*_*____********(8)_*___********(8)_*___********(8)_* . what does mean ?

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?
