Automatic vs Manual on Ram Cummins

[timstevens]

Thank you for your shared experience. FYI... I bought my 2006 MegaCab SRW G56 3500 Cummins new and the clutch lasted 200, 000 miles. Clearly, I have no major tune or abusive habits but, it is a lot of town driving with highway mixed in. What a great truck! I only wish the tow and bed ratings were higher. A 5th wheel rating of 20k or a bit higher would be helpful.

be well!

I have a 2003 Ram 2500 5.9HO NV5600 6 speed, it has 360, 000 miles and still has the original diesel injection pump, original injectors, original clutch, and original power steering pump, it does need a little work but it runs great, and when I drove across New Mexico doing 65 with no load I got a calculated 33.8 mpg, when I had to tow my friends 2008 Chevy 2500 Duramax 200 miles I got 20 mpg and barely felt the load

Swapped my 07 5.9 48re for a G56 about a year ago. Hands down, I prefer the manual. As to what is best... that depends on each individual's use. 48re was okay for a simple daily driver. Gears spread too wide for towing. Often, it was not in the gear I wanted. And no torque converter lockup until 3rd (though I did add a mystery switch). For the G56, towing is awesome. As a daily driver, it's a lot of gears. But I'll take the towing positives all day long.

68rfe here no issues yet. 122k miles towing since day 1. Tuned deleted. Leave it turned down on tow 40hp. I think the main issues with the autos is young kids getting them turning them up high as their tuner will go and beating on them. Or towing heavy in 6th gear lugging the engine/trans.

Also terrain plays a role. Having smooth torque starting off on a steep gravel incline reallly helps. At the same time cruising at certain speeds up incllines the autos really dont know which gear to choose sometimes.

I have the G56 with 3.73 and South Bend clutch. I like to start in 1st to maximize clutch life. Not as fast off the line, but very fun to drive.

Auto and manual are both overdrive transmissions. Cruising speed in overdrive depends on tire size and axle gear ratio.

Another great video. Definitely like the auto for higher speeds. Stock truck power is plenty for what I do.

My truck has the G56 with the 3.42 rear and at 115 mph I still had another 500 rpm before redline. The truck pulls like a locomotive can't drive on went pavement with out spinning the rear tires so I have to Generally put it in 4wd to prevent that. It runs like a beast. And the manual is the better choice over the rfe transmissions in the 2500 4gen trucks all day every day.

Great video I have an 07 5.9 g56 with 4:10 gears

I will take the stick shift every single time. Even in traffic its no bother at all.

When i see gearbox oil change, I figure: EVs are so practical. Especially in hilly regions with hsirpins, and city roadd.

I appreciate you I've been debating which one to get amd how reliable they are or what would work best for me.

Pre 2008 it's the manual 7 days a week and and twice on Sunday's!!!

[joshuaphillips]

Do you think that a built 48re can be just as good or almost just as good as a g56 when it comes to towing? I'm debating either doing a stage 2 48re or doing a g56 swap.

[koolkeith]

I heard a flush was a bad idea for the 48res? Do you always drain but not flush the 48re?

[mjgarcia]

Awesome video man. I’ve got a 05 Cummins with a 8in lift and 37s and the 48re is going out. I’m planning on swapping to manual when the auto finally goes out but haven’t decided on a NV5600 or G56. Kinda leaning toward a NV just because I’ve heard it’s a little more stout. But the G56 would be slightly cheaper and easier to find. Any recommendations?

[wynnholdal]

Please, what do you use for g56 lube?
