10 speed autos next?

[Bill Stockard]

And killing un-needed cylinders under light load cruise

My wife's Honda has that feature and it's seamless. If it weren't for the "ECO" light on the instrument panel I wouldn't know or feel it's happening.

I'm with you Nick. . I just want a double OD 7 speed manual.

Why double over, just wondering?



One over with about a 7. 00 to 1 first and 3. 50 rear would be good or since it is Christmas time a 7 spd direct, 8. 00 to 1 first and 2. 75 rear:-laf

Bill,

When I got my Dodge 5. 9L I bought it just for the powertrain combination, and now I'm darn glad I have one of the simpler 2005's with a strong less complicated engine and the handshaker was not optional for me, it had to have it. If I ever need another truck, I'm not putting A/T's down, I'm just stating my prefference and I'll do everything possible to make sure it has a clutch pedal. Or maybe just run this one to dust.

I agree, the Cummins sounds funky with an auto

Yeah, I was a confirmed 6-speed manual driver (2002 HO with NV5600) UNTIL I found myself stuck in Williams, Arizona with a back injury that also affected my left leg. I could barely sit up, and using the clutch was out of the question. My wife just about went nuts because she didn't feel that she could tow the 5th wheel all the way back to SE Texas by herself driving the 6-speed, so she gave me the ultimatum: "I'm never going to get caught like this again. Either you get me a truck that I can drive, or we're quitting RVing. " Thus, the 6-speed automatic in my signature.



Having had it for over 2 years now, I have to say that I'm getting spoiled by it, even after the pinched nerve in my back was corrected. I always wished for a 7th gear in the 2002 which had 4. 10 gears to tow our 16,000 lb 5th wheel, and the 6-speed automatic fits the bill there (1612 RPM @ 60 MPH versus 2000 RPM @ 60 MPH), and my wife drives probably 50% or more of the time now. So, in my case, a good 6-speed automatic like the 68RFE does have its place. Horses for courses, I guess... ...

My oldest son is also a manual transmission guy but he is going to buy an auto this time. He was disappointed that the 2013's are so late because he needed to replace his '06 this year. He sold it out right Friday so he is dealing on a '12 Mega Dually with Max Tow but says it is a 3. 73? He is kinda worried because I have told him (based on Rusty and Harvey) the 4. 10 and two overdrive auto is perfect and I agree.

I like the double OD vs taller diff ratios because you split the gearing reduction up, and thus the heat generation. The truck with the 2. 75 rear would make more trans heat than the one with the 4. 10's, given the same rear wheel power.

 

[cojhl2]

Mine does have the optional power steering and AM radio..... :-laf

My restored 67 short stepside (in the family since new) has a 4spd w/ compound low and 4:11 axle and 6cyl 250. No addl options. Cost 2100 new.



Would not fit in today's world of 5vrs but for many years it ran between WA and MN pulling a popup to visit grndprnts.

That trans is likely the NP 435 'ol reliable... . About your signature; what does one do with a CAT D2 and a D6????

 

[Wayne M.]

This just in!!!

This could change everything...

More info... Stillborn? I remember hearing about it- then it was gone. Cerberus really screwed things up...

Only if I am not in the top gear (direct) the gear you use the most. But yes, if I am in any of the lower gears, the torque multiplied in the transmission v/s the rear axle does create heat, however so does the two overdrives. The disadvantage of a direct drive transmission and lower first gear is case size. The bigger first gear is physically large so it requires a larger case which creates fitment issues in a pickup sized vehicle. It does mean more oil capacity tho.

The other factor is driveshaft speed. A multipart shaft with hangar bearings really whipping is something to consider. If there's no NVH issues, it's nice.

Hi Wayne,



Well the Cats don't fit exactly into Ram Diesel discussion other than I am as excited about tractors as I am about these pickups.



We used Cats for farming on the hills here in the West. There were 100's and probably 1000's of them around here since they replaced horses and mules starting in the early 30's. In the early 80's rubber tires and tracks started to make steel tracks obsolete.



I drove these things from 12yrs old and have always loved the clatter and roar of steel rollers on rails.



My Cats are mostly just to have and keep them from the scrap yard, but they do get some use. The D2 has a dozer blade and it has recently cleared a lot of brush from one of our neglected pastures.



Well anyway I ramble,, thank you for asking Wayne. .



Oh,, and BTW I am sure you are right re the trans, I remember seeing that in the doc. It is the same trans we had in our 37GMC pickup except for syncro in 2nd,3rd, and 4th. Oh,, and also the little lever to protect reverse.

This IS the other vehicle forum, the cats fit right in. I'm sure others beside me would love to see them in their own thread. Indeed there's no sound like those tracks at speed, and that is one piece of equipment that's unmatched by anyother manufacturer. My employer had a whole fleet of different models at one time. Yes, the rubber has taken over.

Hydraulic or Cable blades???



Starting motors on both?????

Hi Mike,

The D2 (1940) has a starting motor and although I have the necessary parts to convert the starting motor to electric start I have not gotten a rountit yet. So it is still rope. One D6(1959) has the starting motor with electric start. The second D6 (1959) has been converted to direct electric start.

I would just as soon that 2nd D6 still had the gasoline starting motor. Just this fall I had to install 420$ of batteries on it, also you cant beat the sound of the starting motor rattling up and down the valley early in the
morning!!!

Oh,, and the D2 (the only one with a dozer is hydraulic.

The days of super lean combustion are over. Starting in 1973, everything ran (or attempted to run) super lean. Chrysler used it on some of their engines to negate the use of a catalyst. Honda had their CVCC system which also did not need a cat. With the advent of the three-way catalyst for NOX control, engines run at stoichiometric mixtures and I think that's the way it's going to stay.



Future FE improvements can be accomplished by removing the 500-1000# of useless junk that newer vehicles are saddled with.

I did not realize we ever got serious about lean burn. . How come it was not feasable( ie why did we drop it?)

Chrysler never got it to work well. I doubt the others did either

I think Chrysler was really on the right track- and years ahead in thinking/ engineering BUT the computer technology simply wasn't there. The Lean Burn system was an analog computer. YIKES! The TPS was a slide wire wrapped on an eccentric...
