x50v

Sold my 06, bought a 2014 4x4 Laramie Cummins. Bought one that was a lease vehicle, saved my lots. Love the truck. I just finished adding my 40 gal/tool combo box, 5th wheel elect and hitch.

I have been looking at buying a 2013 3500 4x4 with the aisin trans, but currently have an 06 2500 Cummins. Was wondering what the fuel mileage is on the 3500 4x4.

I have been looking at the 14 3500 850 tq. srwd. But don't know the hiway mileage at about 65 mph.

Spotted trans fluid coming out of the bell housing pan, 4 drips only, guess what ever is wrong with the trans will eventually fail it to the point I can tow it in and have Jasper fix it correctly, Santa Maris Diesel failed to notice the fluid leaking from the tranny, if the saw it they ignored it. I will see how it goes on my next RV trip. Have no problems unless I am towing my RV. I will post again when it finally fails. Thanks everybody for sharing all the possibilities.

It shudders only when towing up a slight grade; only when the torque converter is locked; only between rpms 1700 to about 2100. If I am not towing then it will only shudder if I lock the converter; put it in tow/haul mode; shift lever in second; load the drive train to the point where it won't unlock the converter in second gear and then it will shake the heck out of the truck. It seems to be a harmonic, my exhaust system is very tight in the hangers and I don't know if it is transmitting the vibrations? My truck is 100% stock except for the Jasper 3 disc converter and transmission (is it possible for the converter (which has enough mass) to lock, then be out of balance, or become off center and cause the vibration?

Well they said they troubleshot per jasper and nothing wrong. I can't believe it didn't throw a code. Guess I have to have a breakdown.

Two weeks in Santa maria diesel no calls back. I called twice. They said they drove it and it is fine. I said I told you it only did it while towing, did you ckeck for a computer code? NO!! I said check for a slippage code,still no call back.

No carrier bearing single drive line.

Has anyone had a flex plate crack and have this issue of a vibration under heavy load felt through the floor mainly?

Got home from my 10,500 mile trip on trans #3. Still can't figure it out. Fluid is a little high on the stick, they said they used synthetic fluid, also when I was taking my rv back to storage, I got on it. 1st was fine, 2nd shift and tq lock was fine, 3rd shifted fine, but when the tq was sent the signal to lock, the engine redlined, then I backed off, the tq of course shouldn't be it as it was unlocked under load, then when given the command to lock... maybe the clutch pack lost fluid pressure and slipped the clutches? I am going to try one more 500 mile pulling trip, I think I will have to take it to Santa Maria Diesel for warranty work for #4 trans and TQ.

They are putting in synthetic fluid or the dodge, they say - - - Updated - - - I am in Lompoc, CA north of Santa Barbara

Well, lost 2nd gear on stock trans at 70,000 miles. Put in new Jasper with triple disc converter, got 5 miles, hit slight upgrade and got a bad shudder as driving on the bumps on the side of the road, never had this issue on the stock trans. They replace the trans, same problem, replaced both u-joints, same problem, they said they couldn't figure it out and good bye. Drove another 1,000 plus and found code for overdrive and converter slip. Replaced and installed #3 trans, still shudders. Had a Dodge dealer check out the truck while #2 was in and they couldn't find anything wrong. With #3 in, test drove (put in 2nd, tow haul mode, exhaust brake on to lock converter) shudder in 2nd brakes on at 35, also shudder towing up slight grade, down shift to 3rd no problem. Anyone experience this? Jasper found an issue with the torque converter on #1, they are supposed to call me after the teardown of #2. Update......Well Jasper called and said nothing was wrong with trans #2 and that it was my truck. I said I drove into the shop no shudder and drove out with a shudder, how can it be my truck?

I had to replace the water pump on my other brand of truck and it was expensive, about how much do ours (06) run?

thanks to all I had better change mine. ;-}

Sounds like our water pumps don't last too long? I have 64,000 miles on my 06
