I have a 1 ton dodge ram dually, it's my first diesel pickup and I've been bitten by the diesel performance bug, I have upgraded my engine and was wondering just how much power my 4 speed 48RE handle? No stupid answers please, it does nothing but discourage Yahoo users to use the wonderful source of knowledge that Yahoo Answers has to offer....

As you know the weak link is the transmission at this point; the max torque the transmission is rated for is 675 ftlb of torque and stock your at 610 ftlb torque--this is the factory spec.. It is recommended that anything over a increase of 50 Hp or 75 foot pounds in torque should require you to change the Torque converter. With a horsepower increase of 75, or a torque above 110 ftlb should also require a deep alum. transmission pan, extra transmission cooler, and a transmission kit. Anything above 150 hp or 150 ftlb of torque should require a complete transmission upgrade like a TST or ATS transmission. I have too upgraded my engine before; while thinking as long as i didn't just put my foot down that often--I should be fine. I was wrong-- transmission was acting like a 6 speed--that is the feel of your transmission slipping. I now see these everyday with low power complains only to tell them that they need a transmission that i can't build--but can install.
**** do not install a High Stall Torque converter, you only have 3200 rpm to play with and the added heat from slipping will burn everything to the ground. Because of wanting to limit heat and slippage you want a low stall full lock up converter with at least 3 clutches and a billet back (those little brazed on nuts don't stand a chance)

I would get in touch with somebody like banks and ask them they will understand how much strain your putting on your transmission by your upgrades.They will also carry the necessary parts to beef up your transmission.At a minimum I would consider a beefier torque converter other than that you might not have to do anything else to be able to handle 750 or more foot pounds of torque.In a diesel its the torque not the horsepower that kills the transmission.

The transmission will take more than the driveline can handle.
If you order a kit to upgrade, all the necessary components will be in there. Included will be a high stall torque converter to keep from tearing out you driveshaft every time you floor it.

your dodge with the right upgrades will produce over 500 hp .
