When I started this project I had three of them so it made sense to use one with the FE3 swap given the cost: $0. Even buying one used isn&#8217;t a huge financial set-back, as they usually come up for around $150. In addition to the small price, the five speed is also a complete bolt-in solution. The biggest job is swapping out the Miata transmission&#8217;s front section with the same from a Mazda B2000. Since the Mazda truck came with an F series engine and used the same center section\/case, the front section swaps out directly with the Miata piece and bolts up to the FE3.<\/p>\n<p>Pulling the transmission&#8217;s front section is a matter of removing the bolts that run from the rear of the center section, and then using a puller to separate the case. There are tools made for the job, or a DIY puller can be constructed using nuts, bolts and some steel scrap.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone\" title=\"Miata FE3 transmission\" src=\"https:\/\/fe3miata.com\/site\/wp-content\/images\/FE3v1-gallery\/images\/transmission05.jpg\" alt=\"\" width=\"600\" height=\"562\" \/><\/p>\n<p>The junction is sealed so the process does require some effort, but once the seal is broken, the sections separate quite easily.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone\" title=\"FE3 Miata separation of transmission case\" src=\"https:\/\/fe3miata.com\/site\/wp-content\/images\/FE3v1-gallery\/images\/transmission01.jpg\" alt=\"\" width=\"600\" height=\"523\" \/><\/p>\n<p>With approximately 2,000 miles on the transmission since installation behind the FE3, it started to show signs of fatigue. There was a new noise that was growing louder which I took as a warning and swapped it out for the spare. Once out the input shaft was noticeably more difficult to spin, requiring two hands with significant effort vs. a single hand with far less oomph for the replacement transmission.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone\" title=\"FE3 Miata transmission front section gears\" src=\"https:\/\/fe3miata.com\/site\/wp-content\/images\/FE3v1-gallery\/images\/transmission02.jpg\" alt=\"\" width=\"600\" height=\"451\" \/><\/p>\n<p>Once the front of section Miata&#8217;s transmission is removed, the small gears and shafts are exposed.\u00a0Given the small size, I think it faired well for going 150,000 miles and then being put under 250+ ft.lbs. of torque for 2,000 more miles.\u00a0The front section houses the bearings that support the shaft ends.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone\" title=\"FE3 Miata transmission front section\" src=\"https:\/\/fe3miata.com\/site\/wp-content\/images\/FE3v1-gallery\/images\/transmission03.jpg\" alt=\"\" width=\"497\" height=\"600\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Miata transmission is adapted with off-the-shelf parts to form a bolt-in solution for the FE3 engine swap.<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7,1,9],"tags":[38,40,41,20,26,22,23,39,17,15,25,16,18,42,37,21,19,24],"class_list":["post-120","post","type-post","status-publish","format-standard","hentry","category-the-first-fe3-miata","category-projects","category-original-build","tag-5-speed","tag-b2000","tag-b2200","tag-crushed","tag-engine-swap","tag-fe-dohc","tag-fe3","tag-five-speed","tag-mazda","tag-miata","tag-modified","tag-mx-5","tag-mx5","tag-swap","tag-transmission","tag-tree","tag-turbo","tag-turbocharged"],"_links":{"self":[{"href":"https:\/\/fe3miata.com\/site\/index.php?rest_route=\/wp\/v2\/posts\/120","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/fe3miata.com\/site\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/fe3miata.com\/site\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/fe3miata.com\/site\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/fe3miata.com\/site\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=120"}],"version-history":[{"count":10,"href":"https:\/\/fe3miata.com\/site\/index.php?rest_route=\/wp\/v2\/posts\/120\/revisions"}],"predecessor-version":[{"id":123,"href":"https:\/\/fe3miata.com\/site\/index.php?rest_route=\/wp\/v2\/posts\/120\/revisions\/123"}],"wp:attachment":[{"href":"https:\/\/fe3miata.com\/site\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=120"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/fe3miata.com\/site\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=120"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/fe3miata.com\/site\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=120"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
