yep, very durable  

looks like we've got a stampede,LOL everybodies on it at the same time;  

Notice the 2 piece case. The AX-15 has a 1 peice case.  

Man my head hurts now.  

thank you ,thank you ,thank you,just give me ten minutes to soak it all in and my head will be hurting.  

so all in all my tranny is no good but the np 231 transfer case is good?would it be a 32 spline in the 1987 jeep commanche auto matic tranny and 4.L?  

thank;s jeepnut and mudb8.  

just seen that my tranny has aisin stamped on it and my transfer case is a model 231 ng with a ratio of 272 new progress gear is this a good transfer case?  

Thats good. In my personal opinion, I think the t-case is a good case. Of course, there are better ones, but its good all around t-case. One thing to look at....it is chain drive vs. a gear dive. The case is aluminum case. When the chain gets loose, it will sag and eat a hole in the case. look for metal shavings in the oil when you change it. If you see them, its possible that the chain is eating a hole in the case. This was told to me from an older guy that has been dealing with Jeeps all his life....60 yrs or so. He said he has seen 1 or 2  like that. Thats my 75 cents worth.  

the peugeot is a good tranny for what it was designed for, despite popular belief. It may not be a choice swap but if thats what you have run it till it quits, which will be a long time.

as for the 231....you'll likely wear it out before you'll break it provided it is properly maintained.  

hey jeepnut thank;s a million for the info greatly appreciated.
