Upgrading the 48RE!

[DRAG DIESEL]

Steve right on cue, warranty denied , no issues , install problem, look somewhere else. As I said before you guys can believe what you want, buy what you want, we really, really dont care. We have paid and paid dearly but our customers did not. Bottom line when we trust a company to do a job and they cannot do it properly and deny when they do not, they dont get to do it anymore. Thats all , end of story.

. I'll use this later

 

[Stefan Kondolay]

You do that DRAG DIESEL .

 

[ChadHarlan]

You are making alot of friends there Jake

Ouch. . I prefer to be educated on what I don't know so I can make a buying decision that works for my needs. Surely you don't mean that like it sounds.



Lets turn this thread Upgrading the 48RE around and talk about what is needed/recommended for various hp levels or change the title.

Hi Kevin, sorry to hear about your trouble's!

We have not built t/c's for D. T. T. since Dec-15-2004.



hmmm! i wonder if there even our t/c's?????



As for 3 different V. B. and t/c's and the problem is still present, i would really change direction in finding the root cause.

Very good point you bring up, but we have done everything possible to get this figured out. Jon at Floor it Diesel had my truck for a while, and went through the whole transmission and measured all the specs and went through the clutch packs. Everything was perfectly fine. We are to the point where there is really only two things left, a crack in an internal passage of the case, or three bad torque converters in a row. Who knows... ...

 

[Matt400]

or three bad torque converters in a row. Who knows... ...

What about "where" those TC's were built? They could be left over TCS stock or all from their new builder who ever that is.

Chris Kringle,

I dont think i would buy a TCS converter, i put a full rebuild DTT with billet input on jan 10 or 11th i think, with 89% converter. As soon as i got my comp hooked up the converter started slipping. The converters that DTT has now are better then the TCS as im pretty sure they changed them somewhat. Also, the 500 dollars sounds pretty good, but you have to pay about 400 to get it to your door as they do not have a warehouse in the US so you have to pay customs charges and shipping, which will add up very quick.

There is a TCS in Chino, CA. You can buy a low stall TC from them and not have to pay customs.



They make some parts for my multi disk TC.



In order for a torque converter to survive it has to have one of three things.



1. Increased line pressure to the apply piston. (Higher line pressure)

2. Lower stall stator to bring the fluid coupling RPM's closer to the lock up RPM's



3. Increase the clutch lining area. IE. Multiple disks/more clutch lining area



1 & 2 are almost always both needed.



DTT does increase the clutch lining of the lock up clutch a little. They (the ones that build there TC's) machine a portion of the apply piston down and bond another ring of clutch lining there. Its the same principal as installing a wider 2nd gear band.





At high power levels the 89% stator does not have a low enough stall to keep the lock up clutch from burning. You have to go lower in stall, or go with a multi disk and choose whatever stall you want.

Just to clarify re : Customs in case you were referring to DTT, our customers products are shipped from our warehouses in Washington State. So they pay the UPS shipping charges from Washington only and cores are returned the same way.

why doesn't drag diesel have his vendor affilaition under his handle?

 

[bchesley]

I have finally made up my mind, I am going with DTT. I am having the work done with local installer in Texas. I chose them over the other ones because of the knowledge and fuzzy feeling that I got from the installer. I am not qualified to say that the other products are inferior, but I have read enough feed back on this board from people who have DTT trannies and love them. So unless there are a ton of people blowing smoke up my rear I think that I will be happy. I will post results in a few weeks. Install will take place on the 29 of this month!!!!! I can't wait!!!!!!

No smoke here, I wouldn't take anything for my DTT.

Brad

I don't understand?? Why are you going to upgrade your transmission? Is it slipping? Is there something wrong with it?



I would wait until you are at a higher power level.



I am sure you can just add a TC and do some VB work and the trans will last the rest of its life with what your putting through it.







Justin

 

[bchesley]

There are several reasons. I will be adding more power as money allows. I use my truck for my business and I am over building it. I want to have some peace of mind that if I do play hard with it that I wont be sitting on the side of the road. If my truck is down so is my income! I would rather be able to add power and use it when I want instead of finding the breaking point of the factory components! I also spend alot of time out of lock up and want a more effecient converter to aid in mileage.



Brad

 

[Beast2B]

i like that direction, Brad. overbuilding now, even if you don't increase to a power level that uses every ounce of potential, can save headaches and money in the long run. if you run equipment that handles 500hp and you run 500hp, aren't you close to the edge of the envelope? some people prefer to add what's needed as it comes along, some prefer to build it bigger/better/faster once 'just in case' things change. probably a factor of available funds as well as time and personal experiences.

Brad

Are you going to tow heavy with it?



That will be a huge factor in the stall you will want. Or are you going to run a large single turbo?? That will also be a factor.

 

[bchesley]

I tow a 3500 lbs scout/buggy on a 1200 lb car hauler, or a 1983 ski nautique that ways about 3500 lbs. I never intend to tow anything else, and if I do it will be a one time occasion! I am going to go with a 89% converter as advised by the installer. I might in the future go with a mild set of twins to handle 500hp. I just down know yet. As time goes on there will be more options for performance parts so I am just waiting for the perfect combo!!

Brad

89% stall should fit your needs very well.



You have to look at stall speed kind of like starting out in a certain gear with a stick.



The lower the stall the harder it is to start a heavy load moving. Add a bigger, slower spooling single turbo along with that lower stall it could be a nightmare to get a load moving.



I have allot of experience with testing stall speed with different converters. I am going to pull mine out this weekend and throw in a "dual purpose" stator that will have the benefits of a lower stall, but will allow the vehicle to get heavy loads moving without showing everyone how much smoke I can make.

TCS converter is NOT = a DTT converter! Ever wonder why DTT no longer uses them?????

Can parts be purchased or just complete transmissions? I know when the 48 came out we had some PM's about a TC & VB upgrade.

Nope, don't know why??

stefan!!!!!!!!! are you for real?

what happened to the last 1700 unit's over the past 4 years??

steve

Why did DTT stop using TCS??
