A833 transmission issue
« on: January 27, 2013 - 05:30:22 PM »
What would keep a manual transmission from engaging any gears?  I can manually shift the gears into 1st-4th and reverse, yet the transmission will not spin the teal shaft.

Tranny is not engaging, the shift forks can be misaligned or your shift rods have gone askew.

I can put the trans in gear from the tabs on the trans.  I can feel it go from 1st to nuteral to 2nd, the same for 3/4 and reverse.  Could it be the shift forks inside the trans that are misaligned?

neil, here are some pictures from the trans, before installation, i didn't see any thing broken. I was told the trans was rebuilt, but not run when I bought it.

This is part of the reason I hate buying A833's. It looks okay from the pics you have provided but unless you dig in there you will never know.

I bought a tranny believing that it was not an OD unit and guess what it was and the retaining clip lip was busted so I wasted a bunch of dough but learned a lesson. Never trust what someone tells you especially with Mopar parts and get them checked out.

I am looking for a backup A833 and have passed on a dozen or so because they were unwilling to have someone check it out before I bought it.

Take this one in to a trusted tranny shop and have it looked at, hopefully its nothing major.

Thanks HP_Cuda,  :wave:

Yes I learned a lesson.  I looks like I will be pulling this one out and taking it in to get looked at.

Damn, every time I get close to driving this thing, with all the upgrades, another set back occurs.  :stomp:  :banghead:

1 he is using the OD side gasket not the correct one
 2 4th gear locks the input to the output shaft so if the input shaft is turning the output has to as well , this eliminates all the other gears in the trans so if the output is not turning the input cannot be either unless the the hub is not sliding far enough to  lock the shafts together  , this could be an internal problem but you say you can feel it shifting

Thanks for the lesson Neil,  I too thank it is an internal issue.  It could be that the hub is not ingaging the shaft.  As for it shifiting, I can feel the speed forks moving but I can not say that they are ingaging. 

I will be pulling it out and looking closer.

Can I ask an A833 question while we are on the topic. My reverse lights won't go out and I had to take the bulb out. What would cause that, I installed a new reverse switch as well.

There is a sensor on the tranny which sets off the reverse light. Most likely it failed and you have to replace it. Usually the problem is the opposite that it won't come on and that could be caused by a bad ground.

I installed a new switch and it didn't fix the problem. Is there a piece inside the tranny that could be worn? The piece that pushes on the sensor.

About the back-up switch: There is an internal piece that rotates over and contacts the switch when you put it into reverse.  You can see the piece and the button in 67vertman's pictures.  So if that piece is worn the button on the switch won't be pushed in enough so the light won't light.  My guess would be that the wires to the switch are melted through someplace and contacting each other to light the light.  If you unplug the wires, does the light stay on?

You definitely have something that is pushing on the button of the switch causing it to stay on all the time. Pull the new one and see whats going on, otherwise to the tranny shop!

Hmm, I'll have to investigate it more in the spring, I'm 90% sure the light was staying on so I removed the bulb, I installed a new switch and it still didn't help, so i'm not sure what would be holding the button down, if I remember correctly when I remove the switch and leave it plugged in the light goes off. It makes a lot more sense if the light isn't coming on to be honest.   :clueless:
