I cant help you there but I may do the same I hace a '93 Rolla and it has slow acceleration and loses about 10-15 mph goin up hills??

A couple of mates here both have 4agz engines in AE82's ones turbo ones supercharged, anyway I think the AE101 box(c56) is almost a strate drop in, they use AE101 gze box's they are heavyer, and stronger but the ratios are for a toruqy engine
