Engine/Transmission (1998.5 - 2002) Broken auto trans output shafts

[HVAC]

I'm wondering what the next step is along the diagnostic trail? Pull the tcase for inspection I guess. If the tailshaft is broken then once the tcase is pulled one should be able to grab the transmission output shaft and pull it out of the case? At least is should spin.

 

[Bill Kondolay]

The transfer case will have to be removed. The broken output shaft will be easy to spot. If the output shaft is broken you can replace it with out removing the transmission.
Shanti is not around to do my typing for me so I'am lost so call me I willgive you the details on the how to

jeff you should be ok , its only when you do real stupid stuff that you risk breakage , or have way to much HP on tap and get silly , standing on the brakes real hard and bringing the boost up past the stall of the TC has it side effects .

hvac , when the person pulls his tcase the output shaft will probably be lodged in the t case input , may take a bit of work to retrieve the broken part , the output shaft is about 1 inch in dia and maybe 2. 5 inches in length , the 2wd shaft is over a foot in length .

i have a spare just in case , should only take me an afternoon to be back on the road .

well my diognosis was the same, broken output. but I read this to late and the whole thing is out. I just need to get that shaft now...
what is the part # for the 4wd output?

 

[HVAC]

Looks like the same problem here, busted output shaft. Time to find a remedy for the week piece. How 'bout a output shaft for the HD xsfer case? Then replace the low end xsfer case with the HD?

Also, how 'bout fitting up an output shaft for the turbo 400 and then going with the 205 xnsfer case?

Anyone got a recommendation on an upgrade for the drivetrain?

hey Nowel. . tell a certin red dually owner who is remaining nameless #ad
#ad
that my xfer case is out of a 5 sp truck and is the HD unit. . LOL

 

[HVAC]

Willys, we are wondering if the HD xsfer case can be used with the auto. Anyone??????

 

[Piers]

Hey Mopar-muscle don't bring my name into the broken "output shaft" post, cause I've never broken one. Three "input shafts" & one front hub, but no output shafts #ad

 

[willyslover]

Nowel. . I'm sure some one could build an adapter for this and do a remote unit also. . but it looks like the issue is the shaft not the xfer unit. . my guess is that the auto impaired guys have a heavy enough xfer unit but need output shaft mods to cope with the torque under load . . not an easy one to resolve and I'm very far removed from auto info. .
BILL K. any thoughts

 

[Mopar-muscle]

sorry piers , i'll have to correct that , i thought i was told you had broken one or 2 , my misunderstanding ... guess the undervalved ram didn't have enough in it to break one on the back end of the trans #ad


willys , didn't you guys try that one on an auto already ? there is no difference in the output shaft vs. the tcase used ... i think ... the trans should except either t case . as far as retro fitting not available as of yet and could be done but will be very costly , going to try something out , may have to go out of my way to break another to see if it will work or not #ad

seems to be a rash of broken output shafts of late , just recieved an email from a member ( who shall remain nameless) about a couple of mishaps over the weekend of his and another members possible broken transfer cases . its more than likely not the transfer case and is actually the output shaft of the transmission in the OD unit .

how do i know ? i broke this same part in my trans a few weeks ago , thought it was the transfer case , dragged it to a dodge dealer and found out it wasn't the Tcase .

mine is all better now , i wasn't my own warranty station on this one ( and am feeling a bit guilty over it #ad
) , though i should have been and will be for the nnext pieces that do break now that i am capable of fixing it myself ... need to sign up with AAA for the tows home .

so as a warning to you auto trans 4WD guys , the outshaft is real small and when you have 400 plus rear wheel hp and are using 4WD to launch , even in the dirt , you could come home on a hook .

MM. . My6 tried to put my old xfer case on a 5 sp, his was a LD unit and he was trying to do a hurry up deal and mount my HD unit... transmission output shaft v/s input on the HD was way off size wise, transmission was much smaller. . I did not crawl under to measure anything as my old body was still in semi rigormortis state still #ad
#ad
[from the wreck]. . Mike C. said his was the HD unit so I guess there might be two different size output shaft sizes on the auto's [at least I hope they didn't just down size the input of the HD unit to match the transmission size]
I'm aware of the fancy custom stuff. . and the price that goes with it. . but the price is sometimes worth the effort when a guy is breaking stuff regularly. . I'd rather pay the fiddler once than many times as some guys are doing. . JMHO
[again this was all 5 sp stuff... this new episode is on auto's, both trucks as Adam is now auto also]

 

[Straight6Jeff]

How does the output shaft of a 2wd auto compare? Would there not be enough traction available to break it, say from a dead stop and full throttle mash? I haven't been inside the 47RE, just THM 350/400.
Hey, has anyone else experienced a life-expectancy of about 5K with the BFG A/T #ad

ok guys, Shanti's back,

The relationship between the automatic transmission vs line pressure, clutch capacity & hard parts, is a very fine line.

A mis-balance of any one of these components can lead to transmission failure. That is why there is no such thing as a bulletproof transmission.

The same rules apply to the standard transmission, when HVAC brought his truck up to Canada for me to work on, and i saw the condition of his McCloud dual disc clutch it scared the heck out of me. I had never expect to see that clutch burnt up like that.

As far as breaking parts out of the automatic transmission, the two most common parts you are most likely to break under extreme loads is your output shaft and / or your input shaft.

Piers is special as we all know , he found a way to break his front hub.

Lawrence at DD and I are working on something to help with these 2part breakage.

I am also working with Mopar muscle on a similar project. I would say we are at least 2-3 months away for deciding if its a viable and reliable option.

On HVAC's transmission when i built it, i pointed out to him the exact 2 areas where it might break. I took certain precautions within the transmission to help absorb the shock,however we still did use oem hard parts,and with HVAC's combination of close to 700hp, the odds are against the transmission.

Some guys push to the extremes, and while the extremes are fun for a while, it is ultimately costly.

The output shaft of the transmission is the same whether you have a heavy duty transfer case or a regular transfer case.

Guys, while this may be fun to watch these high hp trucks fight for bragging rights, you should note a lot of what you dont hear is the carnage stories left behind closed doors, as its does not make good pr stories. Keep in mind a lot of the time these trucks are company vehicles being used for promotion and marketing ,these trucks at the end of the day go back to their respective shops for repair.

I guess that was my way of saying ,
while this may be fun to watch,unless you have a ton of money and or the mechanical ability to fix the problems yourself , dont do this at home.

On my own personal truck, i have products on that i do not sell to the general public, i use them R&D purposes. My latest test this week is the super mental injectors from DD.

I have an 18 year who thinks he's Piers, and as a few of you can attest to, lays down a pretty good patch of smoke. I fully well expect to get that phone call, Dad i need a tow truck , i wasnt doing anything, i was just driving.

Adam,

If you are ever looking for transmission parts, go to atra-gears and check under the suppliers in your local area.

Input shafts are the same whether its a gas or diesel, 94+

If you tell them its for a diesel, it confuses them and costs you more,

Output shaft,- 94-95 Dodge Rams 4X4 and 2wd ,
are the same as the ones found in the 360 gas motors.

Ouptup shafts 96+ again are the same as the 360 gas, when talking to the supplier,simply tell them its the short shaft with no governor, splined all the way to the end.

Suppliers seem to have their own part numbers so a description is usually better.

While i do stock these parts, shipping may be more than you pay for these parts.

Buy used gas parts whenever possible, easier to find and cheaper and not stressed as much as the diesel parts.

Bill--is the input shaft the same size as the output shaft?? I guess what I'm asking is it stronger?? I talked to Mopar Muscle yesterday and it would seem if we can't make these parts bigger, thus stronger hopefully, then would it make sense to do, to the input shaft, whatever you're working on with him on the output shaft?? also if you swapped out the transmission for a different one wouldn't there be the big possiblity of setting off codes?? just wondering... ... chris

MM--thanks---chris

thanks Bill for the responce, I got it all together today.
So far this has been the only breakage to date(with an auto). Given this is only the second pull(the first pull was with the r6 tc so was the 1/4 mile race) I've been to and generally drive in valey mode. The first rebuild was my fault for being ignorant. #ad

I'll keep you guys posted but this combo with the new stator tc is great, I can't wait to get the race model. #ad

cris , trans is a trans , as long as you put in a 47RE the computer doesn't know or care where it came from .

chris , input is a bit narrower in some areas , doing what i'm doing to the output should help the input , i think we have less to worry about on input side , running a TC with a heavy front cover is what is killing the input shafts .
