Hey guys,
I have 93 Dodge Diesel 4x4 and was shifting out of 3rd into 4th and felt amost spongy. Totally locked up! Would not move at all. Was wondering if anyone had a diagram of the rag transmission? Or if you may think you know what is wrong with it? Tranny was replaced about 20,000 miles ago!
THANKS EVERYONE!

 

Do you have any idea what kind of hp your truck has? Is it leaking at all? New, salvaged, or rebuilt tranny? Also, have you rebuilt or replaced ur t case? Could be that and not the transmission. What happens when you try to drive it does it just go nowhere like its in neutral or does it kill it when you let the clutch out? The transfer cases in the first gens are chain driven and if ur truck has done some serious towing in its life then it just might be that. Try putting 4x4 shifter in n then put it in 4th and see what happens.

 

Umm . . . . NO.

The transfer case in his truck is the cast-iron cased, gear-drive, NP205.

 

If its stock its a chain

 

Look down at the very bottom/left of the original sales brochure, where it reads: 4x4 Transfer Case.





Gear-drive all day long, always has been in the stock 1st gen Dodge/Cummins truck . . . .

 

^^ He is correct. I think its the 2nd gens and newer that use a chain.

 

Just because the OP mentioned something seemed to happen in the process of shifting from 3rd to 4th, I'm gonna lean towards a tranny problem. No idea exactly what it might be yet, tho.

Can you row the shifter through the gears normally sitting there parked, not running?

If it's not stock and he did the work he probably knows enough about it fix it himself.

 

no np205 is a gear driven trnsfercase. the np203 is a chain driven sloppy case. this most deffinately has to be a trans problem from what i understand because why would the transfercase take a **** when the trans is first to get the beating?

 

If the trans or the transfer case was run low on oil, the gears could have "welded" themselves to the shaft, so effectively it's in multiple gears all at once, regardless of where the blocker rings are. It could have happened inside the transfer case too, jamming that in hi/lo at the same time. All I can suggest is to start taking parts off and see which is locked up.

 

Of course anything's possible, but the typical failure mode for low oil in the rag is bearings, and they will make a helluva racket for a long time before they finally come apart.
