so unless u can find an AMAZINGLY good mechanic...its worthless... We had a corolla XEG 97 manual converted to automatic....and it was no problem at all!!
having said that, orignal is orignal...
btw do pick up the pakwheels magazine september issue, there is a modded rolla SE Saloon, converted from manual to auto and it "looks" like a good job cos the guy spent a lot of money... do have a read.
