Never forget that jeeps have been using *gasp* toyota transmissions for years. They just stopped int he last few years. The AX15 is a r150f from a V6 yota, the AW4 is a A340 also from a yota. Go figure they are both strong. Now jeep even used yota trannies back in the day (think t4 and t5) those are just glorified L and G series tranny's.
Neither of which is strong at all, even in a yota with a 4 popper.
