I have a th350 in my truck right now, we had the truck out to a mud bog a couple weeks ago and we broke the drive shaft the runs from the trans to the divorced t-case when it broke it took out the tail shaft housing. well today I installed a new tailshaft housing and built a new drive shaft. the trans was 2 qts low on fluid from the housing cracking so I topped it off. well I tried putting the trans in gear and it does nothing... its like its in neutral all the time! It does not have any gears. Does anyone have any ideas what it could be? park works so it did not break the out put shaft.... the trans has a b&m shift kit, and a 3000 stall converter....
i know this sounds dumb but did ya make sure the t-case is not in nutrual? when we just put my tranny in my truck last month i forgot the t-case was in nutrual and when i put the tranny in drive i just sat there. i freaked but then relized what it was and i put the t-case in gear and when i shifted the tranny back into drive off i went.
lol.... I thought the same thing but I had my bro look and the drive shaft is not spinning......
trans is gone!
sounds like the trans toasted.... thats the only explination i can think of
how and why? do you think the clutches are smoked or is there something broken internally?
wouldn't it have some sort of gear even if the trans was toast? it will rev right to the rev limiter in every gear.... there is no load on the motor what so ever.
maybe broke input shaft or planetary in side drop the pan see what comes out usually when a divorced shaft breaks it sents a sh** ton of instant power though the trans
its either the converter or pump or busted gears either way ya have to pull it so id rebuild it!! Dacco on Saginaw St.in Flint has all the parts ya need. including converter. Tell um' Roy from Got Mud sent ya.

I will check um out... thanks!
does anyone know of a place that can test a converter and make sure its still good before I go and spend another 500 bucks on a stall converter....
easy way to tell is hook up a pressure gauge to a port with main line pressure, see what you get for a reading. In park at 2000 rpm you should have atleast 60psi, and atleast 70psi in drive.
if your going to check it make sure you have a gauge that can go to 200 or even 300psi.. just incase. That will tell you if you have a good T.C and pump.... but either way its a good idea to replace your TC after a trans burns up... but if the fluids not burnt ya might not have too.
if you hook up the guage here it should give ya main line pressure..
sweet, thank you.

? what does this mean compared to the floor shifter being in the right gear not in nuetral torque bolts are still in

my truck has a divorced transfer case in it so there is a small drive shaft connecting the trans to the t-case. it was not spinning when the trans was in gear...... Checked the converter bolts, they where all there and tight......
what the heck caused this?

bad trans mount? I would say you need a mid plate!

x2
or do you have solid motor or trans mounts and rubber mounts, for example solid motor mounts and rubber trans mounts that could possibly be a cause. ==shrug Your not the first one to do that I've seen it before.
Nope, the problem is right there in the 2nd picture...
steel toe boots have been known to cause this
as have a heavy right foot.
a loose nut on the end of the steering column could also be a culprit ;D
running all the stock mounts on the engine and trans.....
I just about pissed my self hammerlane! to funny! lol

do you run a mid plate with rubber motor mounts or do ya solid mount the engine?
sounds to me like you have some other issue (besides the above mentioned obvious reasons)
alignment or movement of some type issue (bad rubber bushings.. ie trans, t-case,engine, mount etc...)
driving style (seriously) are you launching the truck and staying on the throttle?
it appears to be "shock load" damage of some type..
Motor/ HP rating.. what type of setup do you have?
is your jackshaft (small drive shaft between trans and t-case) a slip yolk style or solid?
its a 355 with vortec heads and a decent cam.... probably around 350hp running stock motor mounts 2wd turbo 350 trans, 3000 stall.... I had a little drive shaft running from the trans to the divorced 205 and I think it bound and broke.... the truck was out of the hole and climbing a wet bank.... not sure if it found dry dirt or what.. it just made a big bang and that was the end of it. it broke the ujoint at the t case and the drive shaft beat the hell out of the floor for a sec broke the tail shaft housing and then ejected its self from the trans.....
I am gonna look the tranny mount over real good when I get home. I have since built a new drive shaft using 1350 u joints and yokes......
I am using the slip yoke that goes into the trans housing..... if that makes sense.....

Ok, to start.. part of the issue is the 2wd trans case.. a 4wd case is thicker in the bell housing area.. (for this very reason).
additional damage to the bell housing probably came from the release of torque,, when the Ujoint failed you were torqed up (on the throttle) and when it failed... all the torque was released almost instantly..
but it still sounds to me like you have a worn bushing issue too..

how much travel do you have in the yolk?? I've seen driveshaft damage due to bottoming out a slip yolk,, if your t-case or other components are moving.. and you bottom it out it will take a yolk out right now.
I think the yoke is three inches.... I have it set to run right in the middle.... so about 1.5 inches sticking out....
the t case mount is welded to the chassis and the t-case is solid mounted to the cross member... should the t case be rubber mounted?
should I step up to a th400?

need to find out the reason for the damage first.. your running the same setup as I am (except no divorced case for me)
and I dont have these issues..
my front driveshaft has broken a few times on me by bottoming out,, a buddy helped me build a new front shaft and we:
measured twice, cut once.. but the splines on the shaft are right at the end of the slip yolk, not enough to be seen.. but right there at the end of the yolk.. since then, no breakage for me, and I launch my truck. this allows for maximum travel.
solid mounted t-case and rubber mounted motor/trans could be an issue like Mudbuster said. if this is in the 1500, 1/2ton frames flex ALOT.. and with a solid mounted t-case and less than 1.5 inches of travel, and multiple breaks... hmmmmm
the possibility of a broken motor or trans mount still exists too, need to check those out real good first.
i will look it over real good when we drag it back into the garage.... I appreciate the help, it would be nice to make it a whole day with out breaking it! lol
YOU DO HAVE A LONG SHAFT THAT GOES FROM T-CASE TO BELL HOUSING LIKE THE STABILIZER BAR DID YA FIND THAT CRACK WHEN YOU CHECK TORQUE BOLTS
IT PULLED TORQUE OFF THE SHAFT
its a divorcedt-case so it does not mount to the trans..... I found the crack when I was taking the bell housing bolts out to pull the trans. ...
well that narrows it down to heavy foot and/or truck landing wrong??? lol... could proly take it to a buider n get yourses guts stuck in a dif. case for cheaper than rebuilding.. as long as nothing internal is too messed up...
