ba 10/5 Question?

Are 87 and 89 ba 10/5 trannys interchangeable? Any modes I should know about?

Yes they are a direct swap, however I would swap in a ax15 instead of the ba10

And it is not really worth it to put in another Peugeot.

But what do I know, I put in two AX-15's in my last YJ after scrapping that POS BA10/5...

Direct exchange, all BA-10s will have a 21-sp output. All AX-15s will have a 23-sp output, and swapping in an AX-15 is a bit more involved (but well worth the trouble.)

Go to www.naxja.org, and look for "Let this be THE Peugeot to AX-15 Swap Thread," I think it's called.

It's not - the only reason I put four of those damned things in my 88 was because I could get 'em just for the goin' and pickin' them up.

Yep - I put FOUR in, meaning I went through FIVE. All failed the same way - first and second gear stripped (at a minimum.)

Why? Because that gearbox was designed for the Peugeot 505 - half the engine displacement, 1,000# less kerb weight, 2/3 of the torque output, and the internals are too hard to be useful in this application ("hard" for steel is "strong" - but "hard" is also "brittle." Bad thing.)

I did a FA report on one for Manufacturing Materials & Processes in school a few years back, since I was replacing the damned thing and ripping it down for scrap anyhow. I learned a lot...
