I just looked at a youtube vid on a truck similar to yours I think. Nice looken truck! The guy in the vid wish his truck had a beer holder in it!

 

I have a question on the 48RE transmission. I noticed the dipstick said to check in N and got me wondering...........on my old 95 Ram with the 46RH and my old 727 torque flights I have always at the very least first start of the day or after its sat for several hours let it idle in N for a minute to get the fluilds moving in the tranny. I was under the assumption the newer trannys pump even in park. Is this still a good thing to do on this 48RE?


Thanks to all!

Yep, read in N. You can modify it to pump in park, but the OEM doesn't.

Don't tow anything too heavy cause the 48RE won't last.

You can get a dealer to program high speed warm up idle that works with the cruise control.

Reading and was thinking you were getting a single cab, but see it's extended. Bonus.

What's your old truck?

 

I have a 1947 Dodge WF-32 ton and half as well as a 1974 Dodge D200 440/727 4.10 gear truck and a 1995 Dodge Ram 1500 Laramie SLT with a 360 that I bought new.

Well have had the truck now about 2 weeks and its just been a great machine............One question I have is what exactly does the TOW/HAUL mode do to the tranny? I understand in 2005 it still goes into OD while later years would prevent it from going into OD.

I seem to notice it shifting a tad harder and maybe a tad longer between shifts. I am guessing line pressure is increased some? Is it bad to drive the truck around town in the TOW/HAUL mode or should it only be used for extreme situations? Does putting it in the T/H mode possibly hurt mpg? What about an empty car trailer? Is this enough to warrant a TOW/HAUL push of the button?


While we havent had really cold winter conditions in Kansas here yet I have been impressed with how fast the Cummins puts out heat. My old Chevy 6.2 would run for 30 minutes before you would get any kind of warm out the vents.

Like your truck. If you drive it like you should the transmission will do a good job. After you drive it a few miles you will know when to use TOW/HAUL. GOOD LUCK. SOUND like you are a GOOD DODGE MAN

 

The tow haul switch has some good features. It changes the shift points and keeps it in lower gears just a little bit longer. It will downshift sooner if you keep riding the brake, as soon as RPM comes down to where it will not over rev when it shifts. Also, very important, if you are in tow haul and pull the shift selector into 2 and keep the speed above 28 mph it will keep the torque converter locked. This means you can pull long uphill grades with heavy loads and the transmission will stay very cool. It will pull like a beast like this all day long with no strain. I know, West Virginia has some steep grades!! I put a transmission temperature guage on mine in the output line from the transmission so I can almost tell you exactly when the torque converter is unlocked. It's amazing how fast heat builds. Once it locks the temp drops rapidly. Heat is what kills transmissions!! Keep your fluid changed and don't dog it around and it will last for years. The torque from these trucks makes them fun to drive. Even in overdrive it does not downshift much. When pulling heavy loads it will shift when it wants to, don't worry about lugging a Cummins.

My 05 has 66k miles now and it has done a good job for me. I pull a 31' 5th wheel or a 23' boat. Drive it at 60 or below on rural flat roads and it will get 23 mpg when not pulling anything.

 

Heck, I have an '05 and didn't know this. You say 28 MPH is the low end, what's the top? What gear will the trans be in? I would hope it isn't second.

Thanks.

 

I have had my o5 with original batteries (until last year) out in -10 overnight. she grunted, but started. I live in wisconsin, and would not bother with pluging it in unless you want quicker heat in the cab. The only gripe i have is she takes a long time to warm up in the winter.

 

Well I had my first wierdorama thing with the truck. I pulled up to a store and was gonna run in real fast for something. Wife and kiddo's in truck and its cold out. Gonna let it idle to keep em warm. I put it in park and open the door and my horn starts beeping like a car alarm (I dont have an alarm) and my gear selector light are all flickering to the beat of the horn. All gears are lit up PRND21. I shut the door and it stops. Kinda move the the gear selector a tad and open the door and all is well............I had this happen the other day I think to the horn only beeped once as I got out and I thought I had bumped the horn button the steering wheel but think now maybe I didnt. Have had a few times where I think I am in gear to move and it dont move. Remove the gear shift level and all is well. I wonder if I am too fast for this new system compared to my old trucks. Hope fully I am not having a problem start up. Anyone shed any light on this situation? Its like the transmission and gear selector are not always spot on match with each other.

Tonight I may many other stops and all was well. I even opened the drivers door with it in gear and no horn beep. Seatbelt on or off it didnt make the horn blow?!?!

Any ideas?

Just my opinion on your horn issue.

There was a TSB that would have the horn honk whenever the truck is running while in reverse, the driver's seat belt is unbuckled, and the driver's door opens. Basically, this keep people from backing up while leaning out the open door. The official reason for the TSB was because on some trucks the shift indicator may appear to be in Park, but is was still actually is Reverse, so the horn honking is a warning about that.

Sounds like this is the case with your truck's shift indicator, so the behavior is normal under the circumstances. I don't have the horn honk TSB installed on my truck (and never will), but when I put my truck in Park I make extra sure that the shifter is locked in position, and I also push my parking brake as an extra precaution. If you do the same the horn honking should be a thing of the past. Otherwise, there are ways to defeat the honking by modifying the wiring of your seat belt indicator, but I would not recommend that on an Internet forum.

 

Thanks for the info. I may try and see if that is the case with my truck. I think it happens when I am moving too fast. I did it again the other day when moving some stuff around. Put it in park and went to jump out for a second. I am now slowing down my shifting movement and notice I put it in park a will then hear a click of sorts and then the P square lights up and all is well. If I go to get out before the P square it honks.

Averged 16.22 mpg on my first tank with mixed driving.

My truck does the same thing if I put it into park and open the door too soon. The computer must catch up a bit and acknowledge that it is in Park before you open the door. Also sometimes it may indicate Park but is actually in REverse. I notice this quite often if I'm in a hurry and backing up to the boat, I slamp it into Park and open the door at the same time, it honks at me. I hated this feature until one day when I was in one of those hurry up modes and trying to hook up the boat . When I put it in park and opened the door it honked, my foot was still on the brake so just to slow down a bit and see what is happening I let my foot off the brake....the truck tried to continue to back up even though the indicator was in park..or near park. Actually after closer inspection, I was not in Park but still in reverse. The detent for the shift lever must be a little off or poorly designed.

If you know about this and just be a little cautious and slower you will not have an issue. Nothing is actually wrong, just slow down and be more thorough with your shift lever and give the computer about a second or two to catch up to your hands.

Nice purchase 47. What part of Kansas you in?
