bratboy1 Posted March 8, 2020 Share Posted March 8, 2020 Hey everyone I just had a quick question... I have a 1991 ej22 from a Subaru legacy L in the United States. There is an opportunity for me to buy a 2.5RS Impreza transmission from 99-01 with the transmission code of TY754VCAAB. Will this Transmission bolt up and work for my engine? I know I will have to fabricate the shift linkage and transmission mount and drive shaft etc, but I was just more concerned if this works out. Also would I need to mess with the ECU at all? Thanks Quote Link to comment Share on other sites More sharing options...
el_freddo Posted March 14, 2020 Share Posted March 14, 2020 It will work. The gearbox is probably an 8 bolt at the bell housing and your EJ22 will be a four bolt. Just use the four bolts to hold the gearbox and a engine together. You will need to arrange a stud for the lower starter motor mount as the gearbox uses this as a bolt in the 8 bolt setup. Or just use the top mount bolt to do the job. Ive done this with my L series - gen1 EJ22 four bolt engine, 2003 forester SG eight bolt (phase 2) gearbox.

heartless Posted March 14, 2020 Share Posted March 14, 2020 dont forget that the drive ratios need to match between tranny & rear diff.. if they dont you will have problems. Quote Link to comment Share on other sites More sharing options...

I didn't have notifications turned on for this post! Thank you for the info! Also for the diff, how do I go about that? Should I just find the diff meant to go with that tranny? Thanks again!

heartless Posted April 20, 2020 Share Posted April 20, 2020 ideally, you find a tranny with the same final drive ratio as what you already have. short of that, yeah, grab the matching rear diff from the donor 1 1 Quote Link to comment Share on other sites More sharing options...
