Can I run the Crazy larry program through a stock driveline?

[BBowers]

I am trying to figure out if I can play around with the crazy larry program from Bullydog and not break my transmission, stock 48re. CAn I smoke the tires and have fun running empty once in a while or should I just keep things conservative wiht the +130 setting which only netted me 104 horses on the dyno? Also, that new BD chip that defeats torque management, will that break stuff if I romp on it?

To give you an idea, the 130 setting on my Power Pup would slip my stock transmission. I think that's the most I would want to put through it without upgrades. Don't know about the BD chip.

I guess no... This think the CL can make 490 at the rear wheels, Which is plenty to break your trans before you really realize it

my buddies 06 ripped the heart out of the flexplate with the crazy larry when they pulled the trans the conver had a heat ring on the converter cover... transmission only made 1 week with the crazy larry should answer your question... .

You must be crazy... . most Dodge Cummins owners with automatics are lucky to get 50-60,000 miles on there automatics at stock power levels. You really think adding that much HP to a stock trany is advisable? My automatic started sliping by 40,000 with pretty much stock power, and ate itself before 45,000 miles. While the Dodge automatic is a tough transmission, behind a diesel isn't it's favorite place. We may or may not have the best diesel engine, depends on who you talk to, but out of the major 3 brands, we deffenitly have the worst automatic.

The 48RE has been a very good transmission, if you are going through 48RE transmissions within 45,000 miles then you are just abusing the transmission.



Many people have over a 100,000 miles on stock 48RE transmissions.

 

[y-knot]

Yes that must be it ... ... I am abusing the darn thing.





Many people have over 100,000 miles on it... ... good for them



I suppose if I would NEVER haul anything or NEVER tow anything, then yes I to would perhaps have gotten over 100,000 miles on her before she THREW-UP. But, Then again I like too abuse it... . lets see, I bought a 1-ton truck with dual rear wheels to TOW and HAUL things that other smaller trucks could not possibly do safely. I adhere to maintainance standards better then most airlines, I run only the best synthetic fluids, fuel conditioners and cetane boosters. I am not over the weight limit of my rig, hauling or towing and I only tow new trailers. I have never gone crazy off-road, run over anyone on road, and would be what most would consider a good and responsible driver. I had my valves checked at 25,000 miles like the manual said, even most thought it was a waste of money. I had my transmission ajusted at 30,000 miles like the manual stated, and the transmissions fluid changed three times. I towed a grand total of 8400 miles, with three different trailers, the rest of the time my truck was empty. Does this really sound like I abused my truck or it's transmission??? I really hope your answer is yes. Some might record long distances with there automatics, but did they use there trucks for what they were suppose to be designed for??? I do not know, but around here there is a steady line of trucks waiting for transmission service, and 90% are diesel. Dodge makes a great transmission for a gasser, but only a decent tranmission for the diesel. Yes if you buy a 2500/35000 truck and simply drive it to work everyday, you will probally have decent transmission life, but if your like me and buy a HD truck to do HD things, then you will see what I mean.

You can run on Crazy Larry with a stock driveline for a limited time. I went through the stock trans and a bad rebuild before my DTT. Then I tore my flexplate into the shape of a doughnut at the drag races. So, start saving your pennies now if you want to run with Crazy Larry.

I have 48RE in my 3500 DRW with 3. 73 rear end gears and I tow a 24' X 8' X 6'7" interior height enclosed car hualer and I have no problems with my transmission.



The 48RE has turned out to be a very good and rugged transmission, so yes if you are doing that much service to your transmission and you are still breaking it, then you are abusing it.



Most on this site and other sites are not having any problems with the 48RE when the truck is stock.



I see in your profile that you are running with a different turbo and a TST at setting 5, so I assume you are well above stock power levels, oh yeah I don't think you have a 48RE in a 1997 model year Ram.



You are running a lot of extra power on a stock 47RE and that transmission was not as strong as the 48RE is. With the power upgrades you have on that truck it is no wonder that you broke your stock 47RE in short order.



I forgot to add you have traction bars.



So lets see:



1. Upgraded Turbo



2. TST on setting 5



3. Traction bars



Yeah right you never abuse it.

Damn the truth hurts

Just to stay on subject I think BBowers was looking to abuse his transmission a little with the Crazy Larry setting. I went through my first 48RE without Crazy Larry. The TC went bad and several of the clutches were wiped clean like someone polished the clutch material right off of them. The 48 is better than the 47 I agree, but it is not what I would call a high performance transmission. Crazy Larry does more than add a little timing, rail pressure and change the map sensor. It seems to increase line pressure and shift patterns in the transmission as well.



So, for BBowers my recomendation stands. Save up for an aftermarket transmission if you want to play with Crazy Larry.

 

[ECappleman]

Just curious other than a jolting feeling, how do you tell if your Torq converter is slipping?

 

[TPoulsen]

BBowers,

I can't say much for the auto transmission's, never been a fan and probably never will OK never say never. On my 3rd CTD all have been 5 & 6 speeds.

As for your driveline I can tell you that mine just got back from the dealer saturday from a total driveline replacement due to 3 u joints and the carrier bearing being shoot (45,000 miles). Mechanic said it was cheaper for them to do a total replacement than to change out u joints and carrier, all good here but man you should have seen there faces when I came in and told them I had a helluva vibration. They was all waiting for me to tell them I experienced the death wobble, lucky for me I have not (knock on wood). OH and amazing enough they covered it all under warranty. :-laf

 

[zues]

I have been pulling with my truck for about 80 percent of the 25000 miles and I had to have the transmission rebuilt. Half the time was stock and the other half was with a Power Pup in tow mode.





Trannys are the week link.

 

[MMotschman]

on a somewhat related note anyone have anyidea how much power the stock manual NV5600 can take? I know I need to get a stronger clutch but beyond that how much can it take without doing too much damage?

 

[EMorad]

I sure hope DTT gets me the flexplate and output shaft I ordered in time. NO CHANCE I whomp on the truck without those in place. I have 25k on the truck and did what I thought was the right build for me at 12k. DTT IS, TC, VB, solenoids etc... . added a little more power and no chance I will try and use it until the trans parts are installed.



Wish you the best of luck, but dont be shocked if ***** happens. I prefer to always tow with the truck and never tow the truck if I can help it.

48re

Early on in my bomobing quest I bought a Juice. With the 100hp setting I took out the ODrive clutches with probably just 6 to 10 full out wot runs!!!! I talked to Tim Holt the transmission Guru out of Fort Worth and he told me, based on my discription what had happened to my transmission. Based on my experience I feel that without any transmission upgrade that probably something around 75hp increase is all you can mess with and not take out your transmission ODrive. It seems the lower end holds together better than the ODrive. Tim said the ODrive clutches are literally paper thin and just won't take the abuse and he's been building these things for 30 or 40 years. And most assuredly don't try boosted launches probably above 10psi without expecting some more problems of major proportions. Your transmission upgrade will be the very best money you can spend and it in itself will be like putting a 50hp box on your truck as you are getting power to the ground. These trucks are rated for 325hp and show 270 or 280 in stock form. You should get close to advertised with a complete transmission build. On the flex plate, (I turned mine into a multi-piece puzzle) I know something about. Yep, make replacement o fthe stock flexplate a priority. I thought I'd save a few $$$ and bypass replacing mine,... wrong! It also cost me a new hub in my expensive tc and took a chunk out of my bell housing and tore the heck out of my rear main seal with flying chunks of flex plate winging around. A key factor in my stock flex plate busting besides I was probably at least 200hp over stock when it happened was the road. It was a somewhat wavy surface and at over 100mph when the truck locked back to the surface of the road while under full wot then that baby cut loose and it's a sound you really don't want to hear again. Just a caution to pick your surface as well as a stretch of road without traffic when testing things on your truck. My $. 02.
