French Car Parts--What was Jeep Thinking?! YJ Trans Swap

If your older 6 cylinder YJ has a 5 speed manual transmission, chances are it is the French-made Peugeot BA10. We have the solution-- swapping in a brand new, more stout Aisin AX-15 5 speed with external hydraulics.
A known weak link, these Peugeot transmissions have an often problematic internal hydraulic release bearing, and a comparatively smaller input and output shaft as well as weaker internals. Being nearly 40 years old at this point, the transmission likely hasn't aged well either. Consider swapping your BA10 equipped YJ to a AX-15, all the parts are available through Advance Adapters!

I have an 87 that's has been converted to the AX-15. Does the factory 87 starter mesh with the flywheel or did you use the factory flywheel?

[@johnpearson492]

I had a Peugeot BA10/5 in my 1988 Comanche. It shifted beautifully except when cold, where it would simply refuse second until it gained some heat.
My 1990 Comanche as an AX-15 it works flawlessless but definitely doesn't shift quite as smoothly as that Peugeot trans did.

Did this to my 87 back in 98 one of the best things I swapped
Along with a 93 t case w/ sye
44 rear end

Peugeot standard trans is jeeps is NOT a joke, just too many internet rumors; actually easy to rebuild or fix and parts available; I replace a bearing in mine, not difficult and did not have to mess with shifter. Sell it online or to 4x4 shop, someone wants it, worth money, really!! :)

they aren't worth shit.
They are so bad, that they were the first thing chyrsler changed after they aquired jeep AND IT WAS A MID YEAR CHANGE

When I blew reverse out for the second time, I junked it for an early GM NV4500.

[@KiRiTO72987]

Fun I just managed to blow reverse out on my TJs NV 3550, just putting a used tranny in for now (budget constraints) but I see an AX-15 in my future

After about a thousand views of YJ engine and trans swaps on YT, I've decided to go with a engine rebuild on my 1988 YJ, and upgrade to a Clifford manifold and do the Chevy 4.3 Fuel Injection Kit. I'm also gonna replace the trans with an AX15. I've replaced and upgraded literally everything on my jeep to this point. Figure I'll have a new [old] one before long.

If you love it, might as well keep making it better and better!

[@starrvalley12]

Your lucky it has the external slave cylinder, I have the internal slave cylinder on my 87 yj I will have to change the bell housing for the external slave cylinder and a few other things, some bad designs on the 87 yj .

Thank you!

[@mattryan2291]

I'm looking for those stock Sahara rims if anyone comes across a set!

[@brucea822]

So what about an automatic swap
The 3 spd 999 to a 4 spd. Auto?

[@pattkinder612]

Not enough room for a rear driveshaft with a 4 speed auto in a YJ.

[@brucea822]

@@pattkinder612 that’s what I thought but figured if anyone would know you would 👍
I sure would like the 4th gear
Thanks for your quick response
You guys are the best

[@kaylacreighton1804]

I HAVE BLOWEN UP 4 STARTERS WITH THIS SWAPP ON MY 87 I BOUGHT THE JEEP IT WAS ALREADY DONE CANT GET ANY ANSERS THIS WILL BE MY LAST OLD JEEP

[@richterman3962]

stop buying junk starters
The kit has nothing to do with it

[@KiRiTO72987]

Cheap starters detected

[@hoppermantis7615]

Well. Had a Beaufort that was French made. Not one marine screw in it. You can engineer the he'll out of something. Give it to the French and all you get is crap.

[@spymaine89]

they were thinking cheap money..............and say automatic you did not say.........
