Car Forum / Dodge / Dodge Trucks / January 20062006 2500 turbo diesel auto trans vibration
Hi all, I just went out to test drive a 2500 with the turbo cummins and the auto trans. I noticed a vibration out of the transmission when first starting out from a stop. Is this normal? I think its the tranny slipping the first gear.... Having had an old 70 challenger with the big trans, slipping the first gear always lead to early rebuilds of the clutch pack.... Any insight would be appreciated. Thanks, > Hi all, > [quoted text clipped - 7 lines] > > Any insight would be appreciated. Having once owned a '95 CTD that went through transmissions faster than it did tires...I'd say that it still sounds like Dodge (contrary to what many claim) still cannot make a reliable tranny with the Cummins. Ummmmmmmmmm, I'd say you're wrong and it depends on use and care.........my 91 ctd has 276000 miles on it, the trans was rebuilt at about 150000 and is still going strong.ymmv. >> Hi all, >> [quoted text clipped - 11 lines] > did tires...I'd say that it still sounds like Dodge (contrary to what many > claim) still cannot make a reliable tranny with the Cummins. My 95 (witch I bought in June 05) had 198655 miles on the original Trans, the clutches just disintegrated.

Gee, do ya think things might have changed in 11 years?? They have. My 05 has been trouble free with the exception of a drone at 65mph that was fixed.

Was that the "loosen the engine and tranny mounts, drive it, then re-tighten" fix? >> Gee, do ya think things might have changed in 11 years?? They have.

Yup, that was the one. Found it buried on the TDR. Gotta do it at idle, about 100 feet each way, leave it in neutral and torque to spec's. Dealer had already done all the stuff recommended by DC, such as balancing drive shafts. Went so far as swapping shafts out of new truck with no drone. No joy. They never heard of the "loosen" deal but now have used it on a couple of trucks and it cured the problem. Of course it doesn't get it every time. ymmv I remember seeing it used on a couple of motorcycles years ago.

And I'd say you better find some facts to back your opinion. SignatureMax "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

Some have had problems with this, requiring a shim above the carrier bearing. It's a simple fix, and one the service department is (or should be) aware of. Try it in reverse. If you feel the same vibration, it's probably not the transmission, as different clutches are used for 1st (rear clutch) and reverse (front clutch). This was a Mega Cab 2500 short bed 2x4..... Didn't notice it when in reverse... Thanks, >> I just went out to test drive a 2500 with the turbo cummins and the auto >> trans.

There's a TSB out on that, and as I said, is a very simple fix. |
