^^^ no man its not that big a problem.
@ati41
sir it is a little technical but not impossible, first the things u need should be of toyota GLI engine compatible, like an auto gear box which can be coupled with 2nzfe, i think the gear box of auto SE Saloon could be put in ur GLI but get it confirmed from a good mechanic, then u would need some other equipment. Like gear liver + cable and also electrical wiring components of the gear + if u want perfection u'll also need meter with the options of gear lights.
If asked this question just for information then i think its enough, but if u want to do this project, then start from here get a auto SE Saloon, analyze its 4-speed auto trany+related equipment, which i m 100% can be coupled with 2znfe, next step is to get that equipment, u can get help from toyota for brand new but i think it ll prove too costly. Other option is Peshawar which ll be better choice in terms of price and availability. Once u have u can get it installed either from toyota guys or mechanic of ur choice, if u decided to use ur own mechanic then remember u ll need a good electrician who have experience of working with auto trannies coz auto tranny have some electrical stuff to be taken care of.
By reading wot i wrote it looks very difficult & confusing(maybe coz of m not explaining good enough) but believe me its very easy once u have got all genuine components, every thing ll slip into its place automatically. We did a similar project of converting a mehran to Automatic, and also converting a Corolla 1.3 into auto was on my list once but then i dropped it coz m not a big fan of Corolla anyway.
Pictures of auto mehran can be found on this link

Also according to my knowledge the 1.3 Japani corolla mentioned above have same auto tranny which our SE Saloon 1.6 had.
