so I have a question about the w50 and w55 transmissions bell housings. I’ve done some research but can’t get a solid answer. So for the people who know more about this stuff than I do rn but are the bell housings on these transmissions interchangeable with each other because I am wanting to do a 2jzge from an is300 and want to be sure they fit without issues before learning the hard way with spending money that won’t work. I also had my W50 transmission rebuilt with a new clutch and flywheel so I don’t want to get rid of it and changing everything.

 

the short answer you need w55 bell housing, long answer is
