Ditch the Peugot BA 10/5 tranny and swap in either an AX15(find a later one with the external slave) or an AW4 automatic. I swapped in an AW4 into my '89 XJ and it was a lot of work, almost a complete change over of the under hood wiring harness. But I think it was worth it, I much preferred it to the stock 5spd and it was much more reliable. I did when I was swapping the engine anyway so the wiring swap over was easier with the engine/tranny out.
