    Which trans do I have?

    1998 900 SE turbo, where do I find the transmission type for this vechicle. I know " Asian" makes one for it. I got a P0741 code on it today and to change one manufactures filter you have to pull the tranny and disasemble it to change the filter, Will be checking electrical contacts and lock-up solenoid also.

    Found the data plate. 50-40LE Aisin trans. have to pull tranny to perform any service work. Are there upgrades to the engine and trans that are worth doing after I pull these out? Anybody out there built up this engine/trans yet?
