What other cars automatic transmissions will fit in 2002 Kia Spectra?

probably none...excepting another Kia models' tranny...new cars are not nearly as compatible as older vehicles are...the big problem I can think of is dimensions. nowadays, with vehicles and their factory components being designed on computers to minimize wasted space, swapping just about anything turns into a nightmare. also, even if one would fit, the added cost of adapting parts which make the swap possible, nullify any economical reason to do it. my advice would be to stick with the tranny you got unless you want to open a HUGE can of worms and give yourself a bad headache. if you need a replacement...autozone has cheap, rebuilt tranny's with warranties. and they'll even give you some money for your old busted one too. an even cheaper route is through a wrecking yard...but you get no warranty, and it's used...a recipe for disaster
