I don't want to imagine how bad the acceleration would be with 4.90s on the bigger tires with a load though

Yea same here, I never see any transmission with them on the market unfortunately, I never even see a truck with them on the market anymore

I have the 200A, 2,300 is usually where I keep it at on the highway, 2,300RPM use to bring me to around 60Mph

I replaced the brake switch under the dash, still the same, 55mph at 2,300RPM. I know for sure now that it's actually shifting in overdrive so my guess is something else electrically is affecting it from lock/unlocking the torque converter, the speed difference is only 5mph, it use to be at...

Just tested, I drove it in 1-3, 45Mph is at 2,300 RPMs, I put it in 1-4th and it manage to do 55mph in 4th at 2,300

I cleaned all of the connectors, now it shifts perfectly fine up to overdrive, it won't go into overdrive until I completely step on it up to 3,000 RPMs. 1-3 gear shifts flawlessly though. I'm assuming like RWH said, the TPS, does anyone have a good explanation on how to adjust the TPS or is it...

Oddly enough, the truck is shifting perfect after I just mess with the wires at the brake pedal assembly, maybe a loose connection can cause it?

Is this the assembly that connects to the brake pedal?

Yea I have this same fan, for me it's much better than the original cadillac valve setup, especially going uphill. I know people say these engines can run hot, but these 6.5s are not no cummins or duramax, the 6.5s are well known for a high failure rate of overheating and crack blocks. I also...

For some odd reason my transmission is popping in and out of overdrive, it act as if it don't know what gear to go, the only way it won't do this is if I get up to 60Mph or really put my foot down. I've done a little research and see people say about some throttle control issue or the TCM, I'm...

Got a hose made at the local hose shop, they got me some really good high pressure fuel hose, definitely much better than the plastic hose on the truck and the hose that I got from napa to use with the ferule fittings.

I was going to write a new thread about this but I figure this would be a great place, I've been running the super singles on the M35a2 for a bit and here's the difference for me (Pros and cons) Better cruise speed 55-58Mph at 2200-2300 Rpm, much safer than the 45-48Mph on a 70Mph freeway that...

Could be 20k hard miles, my broken speedo had around 3.5k and the hours was around 300 if I remember. My transfer case and transmission looked clean but the ball joints look like they seen better days, the radiator looked like someone got in a fist fight with it, the transmission wiring harness...

Mines came with a broken speedo and ever since, I just used a GPS

Does anyone know if there's a particular way to find the actual mileage on the humvees? I'm assuming there's some sort of scan tool that be plugged into the 4l80e possibly? I'm just a bit curious to see how many mines have since I've been driving the truck a lot. My old Garmin GPS said I drove...

Cheap hose clamp and hose can cause that, I had the same issue until I use the Norma hose clamps

I'm currently on the last part of bypassing the FDC which is routing the hose from the back of the filter to the hydrualic head but for some reason, I cannot for the life of me get the hose to seal up with the fitting, sleeve, and inserts. The question I have is do anyone know if there's a pre...

I know this is a dead and beaten on topic, but has anyone yet recently swapped over to a better overdrive transmission or transfer case that's readily available? If so, please tell us what you had to do and the details to it, how much you had to cut the driveshafts, did you need to move the...

Anyone has the exact size for the driveshaft bolts that connects the rear transfer case driveshaft to the rear axle? I'm hoping I can go to the store right quick and get them instead of ordering some, I lost the original when we removed them for a tow

Well, maybe I should've adjust the steering stops, the pitman arm finally ate itself up inside and left me with no steering
