how much to beef up 47re

[dieselpilot1969]

so whats it gonna cost to beef up a 47 re trans for up to 500 hp

Don't Know....

I don't know but DTT, ADT and others could give you the price. I shot in the dark is around $4K

No, you can get a completely rebuilt one with a triple disc torque coverter clutch for about $2550 from Goerend Brothers Transmissions in Iowa. They'll ship it out to you or install it. Or they can beef yours.



I put one of theirs in my 95 and it held up great! Pulled hills in OD pulling a camper at 1100 deg EGT with no slippage or heat.



Do a search on your own, but I recommend these guys.

5k to beef a 48re

i was quoted @ 5k range for my trans :--) . way to much for my budget. i told them id want about 500 rwhp. i dont know what is a reasonable price for 500 rwhp but if 5k is it looks like i wont have a truck with 500 hp :{

 

[curatchko]

5k is a bunch of ****. Someone is taking someone to the cleaners.

 

[Blakers]

Call Dave Goerend about the 48re. I bet he'll be much more reasonable.

Beefed transmission

There is NO middle ground. Beef it to the hilt and you'll never be sorry.

I gotta tell ya'll, that you guys are spending way too much on these autos with these folks... . seriously.



5k in the drag racing world, gets you the best automatic money can buy. And when I say the best, I'm talking Comp Eliminator all the way. We're talking EVERY PIECE internal is a custom made trick of the week, billit this, CNC that, THE BEST. ABSOLUTELY Nothing is left under the case that is an OEM piece.



Now I know I'll have people telling me that Diesels are this, and Race cars are that, but Parts is Parts, and Labor is Labor. This trans will hold 1100 horsepower, 800 torque and an 8500 rpm LAUNCH with a T-Brake. Not too shabby.



This trans is a TH350(yes not a diesel transmission, but FAR advanced than any diesel transmission out there, NO, not as strong, but we're down to material and design in that regard). This 350 is a Comp Elim. piece that is COMPLETELY custom... . every part in this trans has been through intense design, FEA analysis, every single PIECE is custom CNC'd. This is the BEST of the BEST. Light years beyond what these diesel transmission shops are offering in terms of R&D, and Labor hours to design and build. It goes beyond that in things I won't even bother mentioning that add to the cost... .



Price of this transmission? 5500 bucks. And that's coming from a place that is WAY over priced as well.



So when I hear someone get a quote of 5k, for a trans that is STILL mostly OEM junk compared to my 5500 dollar piece, there is someone cleaning someone elses wallet out... . bottom line.

yeah i know... . i wont be dealing with people who quote me a 5000 dollars. . the guys was nice and he was from a big trans company but i will not be dealing with that. anyone know a person who beefs up 48re parts for a reasonable price. heck if anyone can get me a blueprint of this stuff i can make it at my shop for just the cost of material. My extra time is free

from your last post, it seems as if you might know what your talking about. . but that small block chevy junk that doesn't belong on a CTD thread... . LOL You might want to take your BACK TO BACK NATIONAL POINT CHAMPTION opinions to a "small block" chevy site... ... ... HE HE HE HE ... just kidding..... I agree. I wouldn't pay 5k for a bunch of beefed up OEM parts... if your going to spend that kind of cabbage, you better be getting the best of the best... Norm says HI... lolololol :-laf

 

[XcumminsX]

these big trans companys havbe been getting away with these outragous prices for a long time i wonder how much they stuff in there pocket... . supply and demand i guess. the suppliers boosters there prices all up and probably are all laughing at us. .

Chris, I understand what you are saying about the full race trannys,BUT,there is a huge diference between that trans and a 47RE trans in our trucks . And around here the 4K tag will include all upgrades on low mileage units,a deep pan,which is close to 300 alone,all the labor and fluids,a torque convertor ,a totally recalibrated valve body,and many billet parts. On top of that the companys provide a warranty,and at 500HP, a warranty shouldnt even be needed,IMO. That is a race application,there is no such thing as 500Hp truck that is not raced or run full tilt. I feel you get what you pay for here,and a TH350 trans is so cheap,and was so popular ,no lockup TC, no need for it to hold up to racing one day,sled pulling the next,then be a tow truck the rest of the time. I feel you really arent making an apples to apples comparison. If complete diesel transmissions were sold as is,without warranty like the Th350s are,then you could compare an old 727 1st gen diesel transmission to the th350,and that would be fair.

The diesel is a different animal when it comes to transmissions. We're talking about some of these built engines putting out close to 1000 ft-lbs of torque at 1400 rpm. Nothing like a race car putting out what they do at some tremedous rpm. Automatics live easy lives at high rpms, but they have to be really stout to hold up to the diesels.



I wrote to Dave Goerend about the 48re - I'll let you know what he says.

 

[curatchko]

Well I shouldn't have even said Th350 because there is nothing 350 about my transmission. It's a 350 case, that's it. Rest is a custom transmission. NOTHING Th350 inside. That's my whole point.



I understand the RPM thing and the diesel thing. But, there is nothing special inside these 47 and 48re transmissions... . there just ain't nothing in there. Only transmission more simplified is a Powerglide... . Further these transmissions weren't built around diesels... possibly the 48 was but the 47 is the same trans offered in the V10 if I'm not mistaken.



Again, Parts is Parts. Tell me how much OEM is left inside these 5k 47RE's!! I'll bet plenty.



Next, tell me how much one of these big diesel transmission guys would sell a COMPLETELY custom internal 47/48RE for?????? And when I say custom, I mean EVERY SINGLE INTERNAL PART.



The cost should be no greater if not less than my 5500 dollar custom racing transmission.

 

[XcumminsX]

i see your point and totally agree with you

And that's why they don't hold up in stock form.



Actually the transmissions themselves do hold up pretty good; we hear of a few transmission failures, but very few. It's the torque converters that are junk. First off, they are designed for gas engine rpm and will not transfer the power at normal diesel rpms in fluid drive, therefore they rely on their lockup clutches to transmit the power. The clutches are way underbuilt, so it doesn't take long - even with stock power - to slip them. And once they slip, they don't live long.



The aftermarket converter clutches - like the Goerend and ATS - use a more positive fluid drive system and triple disc clutches that hold up lots of torque and power. DTT uses a very fluid solid converter without a triple disc clutch to achieve the same results.



I don't know if Dodge made the 48re any better than the 47re. I have not really heard a comparison.

I heard somethin once but never made sure it was true. There is a local guy who was making huge power here a few years back. Its a 12 v. He had spent more money modding his truck than it costed new.

Now I heard for around 5 there was a company here that would build an allison to suit any application. The north slope liked em for their ford PSD. So 5 could get you an allison conversion. Puts things in perspective if its accurate.

Its not the hp that kills. Hp is just the rate of application. Torque the twisting force is what murders these things. Our engines make full torque at measley rpm. Before the line pressures are up. The transmission isnt ready for all that force. Add the torque multiplication of that junk tc that dc uses. If its not in fluid coupling is it still multiplying? Isnt fluid coupling around 2400 rpm?



I was told that 2 or 3 thousand would get you a 727 torqueflight built to 2500 hp.

That's exactly the issue. I had a Goerend Triple Disk converter in my stock 99 transmission. In the last 13 months I put 50k hard miles, including about 30k+ towing 12k trailer around the country with about 350 horse and 700 torque before I sold it a couple weeks ago and the trans was in 'perfect' health... . 98 and up transmissions don't need all the money that many people are throwing into them.



It's the converter.

well could I not go with an ats triple loc torque converter and upgraded valve body
