BW1354 failure?

[TarHeel085]

Has anyone ever had a 1354 fail on them? ive searched about my problem symptoms, but they all seem to pertain to the 4405. symptoms im having: grinding in reverse and clunking when in drive, not to mention the clunk that comes along when drive engages and there is a "whirring" in nuetral when the motor is revved up.

Its a 1354 manual shift, the u-joints are all still good, and nothing is loose driveshaft related, the case does have a good amount of miles on it, possibly over 150K, junkyard was unsure of milage and ive at least put 50K on it myself.

Ive read about the whole shift fork thing in transfer cases, but does it apply to the 1354 manual? also while i had it down on the ground yesterday i selected every setting and the all worked as they should ie: 2wd only the rear shaft spun, 4wd they all spun.

any help would be great!!

my 1354 failed but it wasnt a manual. sorry i cant be of more help

were you having any of the same symptoms when it went?

Sounds more like the tranny. When you say noise in neutral, do you mean tranny in neutral or the tcase?

i dont recall sorry.. the problem with mine, was i couldnt get disengaged.. so i pulled the front drive shaft and continued to drive it. i replaced the fluid in it weekly, because it got so hot it would burn it. i skipped a week, and fluids viscosity broke down i guess and the case exploded

there is a rebuild log on here. maybe pm glacier if this doesnt get answered

transmission in nuetral, the trans only has 24K miles on it supposedly, so it should be OK, and with the transfer case having possibly 150K miles or more, there is not telling what it may be. i just dont want to pull the tcase back down and have that not be the problem.

If it's making noise with the tranny in neutral, it's not the t-case. Since the tranny output shaft isn't turning in neutral, the t-case is doing nothing. I'd say you have some sort of transmission issue. Not sure what though. Start by checking fluid color and level.

And even with a lot of miles, it takes a bit of abuse to break a 1354, especially since you are in the lighter sport. My truck has nearly 219k on it and the t-case (1354) is one of the few things that has never given me trouble.

fluid is brand new, i literally just put this transmission in this weekend, with brand new Valvoline MaxLife ATF. i thought the 1354 was pretty stout, but i have treated it like crap, pulling heavy loads, lots of hard acceleration etc. i really hope its the case, cause im not pulling that trans again!

 

[Premier]

if your in neutral and rolling, the driveshaft will turn the internals of the t-case, right?

 

[Burns]

Yes if in neutral and rolling the tcase will turn.


The part that bothers me is this:

not to mention the clunk that comes along when drive engages and there is a "whirring" in nuetral when the motor is revved up.

With that being said it sounds like its not the tcase to me


When my auto 1354 failed it did nothing like you said. Mine just slipped and was kicking in and out of drive.

 

[TarHeel085]

i just dont know where to go at this point, the reason i was thinking tcase was the no reverse thing, cause thats where people usually point to first. i really really hope its the case, as im not prepared to put another trans in this thing.

i guess tomorrow ill pull it back in the garage, pull down the case, and crack it open.

 

[TarHeel085]

bit the bullet and pulled it down, pics with the results to follow.

fluid looked like mud in it, now i just need to empty my drain pan as i just realized it was full :thumbdwn:

 

[TarHeel085]

well it was a good thing i popped the case open. it looks like the shift fork is indeed at least part of the problem. the nylon is gone, and the top of the fork (or bottom) it starting to break near the end of the arm. i called a local guy about rebuilding it (as i don't have the tools to do it myself, or the patience for that matter) so i may just get a whole new case and hopefully that will cure my problem. here are the pics

 

[TarHeel085]

well now that ive posted 4 times in a row with no other response, im guessing no one really has any idea what this may be other then the case based upon what i found inside of it.

ill be getting a new one later on this week and installing it to see what happens.

side note that i forgot to mention: the truck was having ALL of the a fore mentioned symptoms before the new trans was installed. i find it VERY hard to believe that two transmissions would having the EXACT same problems.

I think we have more than few problems here.. but have you checked the rear pinion? Cauz that'll definitely cause a few clunks.

I wish I could give some good info.. but when our transfer case broke it "sounded" like the chain went..

With it in any gear you could turn the output shaft (rear) on the transfer case and nothing else moved..

We paid just < $200 for a used xfer case and dropped it in.. and it fixed everything.. (related to the xfer case).

I never opened the old transfer case.. we just thew it in the trunk of the car we turned in so it would weigh more..

Our symptom was constant clicking (speed related) and then one time while on the freeway I got off the gas, then on the gas and then there was no power to the wheels (in 2wd or 4wd).

OK, i just went and checked the pinion, i think. i saw how you posted in another thread IZ that to check it i should try and move around the pinion and so forth to see it its loose. its tight as a drove, all my efforts do is move the truck.

heres the background of what happened, truck was running fine doing 70+ MPH towing a very small trailer with only a matress and a grill on it, no biggie right. i had O/D off like always when i tow something, no matter the weight. then all the sudden i get this horrible clunking coming from the trans, pulled off the side of the road, looked under the truck but nothing. so i pulled back out on the highway, and the clunking got worse. so it was towed a very long way to my house where it sat for close to 1.5 years, i put a second trans in it, got a deal so figured why not do that, now this second trans has a new TC and a new pump.

looks like the fluid is burned up.. hmm, dunno

So we dont confuse ourselves and future readers, lets not use TC because unfortunately the Torque Conerter and the Transfer Case can be a "TC".

It really sounds like you need to plop in another transfer case. If the trans is not the problem, and you're sure its not the rear differential, then it is probably the transfer case. If you feel adventurous, document and take apart the transfer case -- it is a pretty simple machinery and you should be able to see what the problem is. If you need parts, I'm willing to bet that a majority of the internals are the same between the electric and the automatic 1354s -- and the automatic 1354s are all over the place so that shouldnt be a big deal.

fluid def burned up in it, and there was sludge in the bottom of the case as well right near the pickup screen for the pump, this def may have contributed to any downfall of it.

and IZ, thats what im gonna do, unless you have some other way of me check the diff for any problems.

i will tear the old case apart some once i get my new case to see exactly what happened to it, since i dont think anyone has done this for a 1354 yet.
