My local dealer is giving me a very good deal on a 2500 QC with the SO Cummins/47RE auto. The only thing is the truck as a 4.10 ratio. Most of my towing is light duty. Is this the preferred setup with the SO/auto?<br><br>Thanks<br><br>MikeyB

It always depends on what you really want when the $35+ K money is spent out of your pocket. I drive standards, so cannot speak concerning the auto, however, a lot of folks on this site like their autos so they don't have to shift in traffic. The 4:10's may reduce milage figures some, and are generally better for towing the heavier loads (6K and above) when towing often. I think many on this site have been excited about the new 48RE, since it is available for the H.O., but if you're not going to do any towing you probably don't need that anyway. Just my 2 cents worth.

Just playing around with the truck and fuel-o-meter computer.<br><br>I have found I get better milage in 5th at 50mph than I do in 6th at 50mph on those hilly roads in rural Pennsylvania.<br><br>So, I complate rhetorically, what would 4:10's give me.

Get it you won't be sorry, I'm getting rid of my truck because it has 3.73's in the rear and I should have gotten the 4.10's. Keep in mind that manual vs. auto is different in terms of MPG and the way the tranny's are setup. <br><br>If you check the archives there are several already created posts on this topic.

No worries.<br><br>I buy diesels because I like diesels. Can forget all the number crunching...all the gas vs diesel conversations, simply I like them and they are more compatible with the way I drive (I like torque and low rpm power).<br><br>Needless to say...I am not above shifting the transmission if need be, actually find it enjoyable. Out of the 13 vehicles I have owned only one was an automatic transmission and I owned it/sold it in 3 weeks. I like rowing my own and the additional control and desicions it gives me. <br><br>So, if the Cummins can muster 70 mph in 6th with the load on a hill; GREAT! If not I will shift to 5th and enjoy the sights and scenery at 50mph. ( I have yet to tach more than 2300rpm so I dont know how fast the truck will go at 2500 or 2600rpm...waiting for it to tell me when it is ready-&quot;break in&quot;- rather than me push the limit and &quot;break-it&quot. ;D<br><br>However, I can tell this engine has a lot of &quot;umph&quot; and dont think I will have too many worries in the &quot;hill country&quot;. If I do it is no problem, I just get to play &quot;Rubber Duck&quot; and shift some more. <br><br>We americans are always &quot;in a big hurry&quot; in the name of progress...we need to slow down and smell the roses in the name of self preservation.

I have had it to about 3300 many times. 5th gear will go about 65 mph at 2900 or so. If it is going to break it will break weather you do the so called &quot;break in period&quot; or not. I have built a few motors in my time and other then the 30-45 minute cam break in period to drive it like you stold it. Just as my 7000+ rpm 440 <br><br>But seriously, if you don't get on it and work it the thing will take forever to get broke in. Turn it up and enjoy it.
