im looking at running with a single disk till i go with my twins but this will most likely be a year or two before i see twins hanging of the side so till then im going to have around 350 ish hp with my va and the 120s i have waiting for some tranny mods. will just a vb and single disk do me i have tested the line pressures they are with in specs so i dont have any leakage inside. it think it will work out fine but just asking for some input thanks guys

Seabee, I'm looking to do the vb /single disc tc upgrade myself. What I have found out so far, through research and pms to individuals is. Up to 400hp on a fairly healthy trans. SO I started researching when dc updated the trans, 2000 better seals and from what I'm hearing better reliability.

Now, my neighbor has a 99 one month after adding a superchips to his truck. The tranny puked and came home on a wrecker. I think I would have see how healthy it is, before spending the money. If mine were to puke today, DTT all the way!

Just what I have found out, someone can flame away if they like.

I've been running a single disk and shift kit for a couple of years now and it's held up pretty good. If you know your going to twin it or go for big hp, I'd do the entire tranny once and be done with it. Just my $0.02

Might be OK if driven cautiously and without pushing hard while towing heavy. Mine was rebuilt 4 months ago and included a HD convertor. It performed fine until I took a trip towing 11m lbs, then I got left on the side of the road. Still not back on the road but it will have Goerands triple in it this week. Good luck.

vssman , i know i need to do it once and do it right but i want more power now and dont have the funds to build the tranny that i want ie full billet

I'm going with a single disk from TCS, same company that made the DTT converter until they parted ways. I feel like the the steel stator is where it's at, not a modified stock stator. Better fluid coupling until lock up. There are a bunch of guys pushing over 500 HP with a single. With the 47re, when you add a tighter TC your 3rd gear clutch pack will need help holding the extra power. There are a couple of ways to take care of this, cheapest way is to buy a 48re drum and a billet alum. apply piston with a cut pressure plate so you can run 6 frictions. First and second gear just have to have enough pressure and holding power. You can get a better 2nd gear apply lever and a new kick down servo to sure up potential leaks also get a better accumaltor piston with more seals. I would say that would take you to 450 HP easy. I'm not an expert, but I've gotten a lot of sound advice from trans builders and folks here on DTR.

EDIT: Did I have to mention a shift kit? I'm sure most know this is a must.

mike i see that you have just a shift kit with 275s hows that holding up for you. this truck will not be seeing any heavy pulling just normal driving .

Seabee, The shift kit made a world of difference. With just the EZ it was hurting going into lock up. It's been holding the EZ and 275 great. I've towed with that combo a couple of time as well with no problems. I've got over 10,000 miles with this shift kit and power upgrades.

350 RWHP on a M250 (That dyno typically reads 15 to 20% lower then a 248c)

Any more and you will be pushing it.

Seabee, the sheet metal stator that Mike is talking about has a pretty low stall. If you are concerned about smoke I think that would be the wrong choice.

I know where you can get a OEM lower stall stator.

The part number for the stock v 10 stator is 10140 (Very high stall, no good for a diesel)

Stock Dodge stator is 10141 (still too high of a stall)

The Borg Warner stator is 10142 (just right fro anything up to 425-450 rwhp that is concerned about smoke control and also tows anything.

I was told 350HP max with a new VB and single disc or with a triple disc and stock VB.
Add the VB to the triple disc and it goes way up.

Mike D

I hope it won't smoke too much. So, how much would that stator cost with the shop work?

justinp20012500

The borg warner stator? I will have to check on the cost. There is no shop work done, well maybe a little just to get the sprag to fit in there tight. I am testing a new sprag that is held in by a snap ring instead of pressed in. Failure is not common with the pressed in type anyway, just looking for a more bullet proof product.

PM me your email address and I will email you a stock dodge stator, and a 10142 (Borg Warner stator)

IMHO to run a single disk TC effectively u need a full internal overhaul so that the pressures can be upwards of 200psi and all the parts can handle it together...u need strong seals in the tranny at every spot to run those high pressures and after that i dont think it matters whether u got single, triple or five disks.....IMO u can probably get away "temporarily" with more runnign a triple disk by itself because of the added surface area but then in theory u risk having more friction between the disk areas and shavings getting into the tranny lines causing u to rebuild anyway...so my solution and what im saving for is a fully rebuilt tranny that allows me to run through the roof pressures which will allow me to hold under any load..whether i have triple or single wont matter at that point

chasd60

To met that sounds like replacing the rims with every tire change. If it isn't necessary, don't do it. If the pressure test has revealed no leakage then it should be no problem.

The information I passed on was from an expert in the transmission field.
