well let me start off by saying hi..im new and i come over here from Pavementsucks.com.


Next i sank my truck so my tranny is being rebuilt, but i dont have enough money to get a DTT tranny so im rebuilding my stock one except im putting in a suncoast converter and mabye a valvebody but if i dont get a valve body im getting a shift kit. so if i get all these goodies will my tranny hold up to an EZ and DD1s.

What else could i do.

 

Get the torque converter and valve body and you should be able to hold that setup for a very long time.

 

so if i got a suncoast converter and valve body my tranny could hold an ez and DD1 or DD2s? or could i got with a comp box? what do i need to tell the tranny guy in order to turn the line pressures up.

 

If you get a VB it will be set up for higher line pressures. The downside of the higher pressures is that too high pressure will blow out the front clutch piston seal and reduce the life of the front servo seal.
If the tranny is already out you could source better parts from eg DTT. (I don't know about other vendors offering these parts, but I'm quite shure they'll have something like it)

Alpine, your just biased.

 

If you are getting the Suncoast Converter you can also get their Extreme upgrade kit ( http://www.suncoastconverters.com/dodge/ext_upgrade.htm ) or their Intermediate Update Kit ( http://www.suncoastconverters.com/do...er_upgrade.htm ). You can call Suncoast 1-800-868-0053 and talk with their guys. You will need the resistor as mentioned before if you raise the pressure they can fill you in on what to do.
Good Luck

 

BB- yes I am biased, but I told him that he'll have to check for equivalent stuff from other vendors But I have every right to be biased as a satisfied customer. (And before this becomes a tranny war I don't intend to badmouth another vendor, I simply state what I have experienced)

SuperDave- If you haven't decided for a setup yet I'd contact each of the big 3 for advice and for pricing on a complete setup for what you want to do. I know Bill Kondolay from DTT is better reachable by phone than on his website.

Well I have seen trucks with all four trannys and they all perform much better than stock. I would own any of them and have respect for all of them. It takes a lot to hold a tranny together with the low RPM and high torque some of these trucks put out.
Yea I’d be biased to if I was Alpine, Bill K went a long ways to help Alpine when he needed help with no guarantee of a sell afterwards. There are a lot of places that wouldn’t do that.
You need to call them all and see who will do the best deal for you. Your part will be to know where you want to be horsepower wise when you are done. It will make a difference on how they set up your tranny.
Here are the big four:

Goerend Brothers------ http://www.gbtransmissions.com/default.htm
DTT--------------------- http://www.dieseltrans.com/dodge/index.htm
ATS--------------------- http://www.atsdiesel.com/products/products-dodge.html
There is a lot of stuff out there so read careful. Find the one you like then PM some of the guys who have the one you like in their signature. I think most will be glad to give you the info you need.
Good Luck

 

Well I'm a little bit out of the loop on my side of the pond, I didn't want to exclude someone when I said the big three. It seems that there are four big ones now.
My experience with DTT is very good, and I got tons of advice regarding my use and abuse of the truck (I actually offroad it, even went to car trial nationals over here- and finished in an ex aequo first open class-prototypes heavy)
I'm definitely shure that it would be hard to find a transmission and a torque converter less fitting for the Cummins than the old 47RE with the TQ that is on it stock. A lot more hp found their way to my wheels and the driveability improved massively with my setup.
I'd really take the time to talk to the builders for some time about what you intend to do with the truck to ensure you get the best for your purpose.

BBD- I may add that it's the low end torque that tears them up. All the clutches are applied and held by hydraulic pressure. If you are at low rom you don't het much volume from a pump, and a small leak will lead to a big loss in pressure. Many of the trannies seem to die from internla leakage and high torque at low rpm. That's the reason why it's suggested to tow with O/D off. The ranny would try to hold O/D, but at these low rpm the torque of the engine would overcome the holding power of one of the cluthes and voila- slippage- the debris of that slippage will take out other stuff. This explains IMHO the widely differing results with the stock transmissions- more or less internal leakage. And this also tells me why it isn't wise to use just a TC and V/B- the TC will effectively lower the rpm for transferring the same power or transfer more power at lower engine rpm (basically that's what the aftermarket stuff is about)- so you'll need to take care about the internal leakages, make better clutches etc to make the transmission stand this disadvantageous circumstances- more torque@lower rpm.

Just my 2c
