Remove the boot. You can see now the top of the gearbox. Actually it&rsquo;s the transfer case. And you can see oil on the smaller boot and on the larger boot just removed.<\/p>\n<p style=\"text-align: center;\"><a href=\"https:\/\/wardiz.org\/blog\/2017\/11\/06\/gearbox-oil-leak-part-1\/p1060703_1600-2\/\" rel=\"attachment wp-att-1139\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-1139 aligncenter\" alt=\"P1060703_1600\" src=\"https:\/\/wardiz.org\/blog\/wp-content\/uploads\/2017\/11\/P1060703_16001-500x375.jpg\" width=\"500\" height=\"375\" srcset=\"https:\/\/wardiz.org\/blog\/wp-content\/uploads\/2017\/11\/P1060703_16001-500x375.jpg 500w, https:\/\/wardiz.org\/blog\/wp-content\/uploads\/2017\/11\/P1060703_16001-1024x768.jpg 1024w, https:\/\/wardiz.org\/blog\/wp-content\/uploads\/2017\/11\/P1060703_16001.jpg 1600w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/a><\/p>\n<p>On the above picture, circled in red is a crack on the smaller boot. This part needs to be changed. Oil is obvisouly coming from here. You remove this boot by sliding the spring up. Then cut or slide the lower zip tie holding. You can then slide up the cracked boot gently. Clean the oil first to avoid oil on the top of the control lever. You should now have something like the following :<\/p>\n<p style=\"text-align: center;\"><a href=\"https:\/\/wardiz.org\/blog\/2017\/11\/06\/gearbox-oil-leak-part-1\/p1060710_1600-2\/\" rel=\"attachment wp-att-1140\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-1140 aligncenter\" alt=\"P1060710_1600\" src=\"https:\/\/wardiz.org\/blog\/wp-content\/uploads\/2017\/11\/P1060710_16001-500x375.png\" width=\"500\" height=\"375\" srcset=\"https:\/\/wardiz.org\/blog\/wp-content\/uploads\/2017\/11\/P1060710_16001-500x375.png 500w, https:\/\/wardiz.org\/blog\/wp-content\/uploads\/2017\/11\/P1060710_16001-1024x768.png 1024w, https:\/\/wardiz.org\/blog\/wp-content\/uploads\/2017\/11\/P1060710_16001.png 1600w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/a><\/p>\n<p>Now beside the obvious boot that must be changed I don&rsquo;t know if it&rsquo;s expected to have oil in this place. R33 and R32 had a similar issue. But Nismo provided a kind of transmission baffle plate for the gearbox (part number 32150-RS590) to solve the problem :<\/p>\n<p style=\"text-align: center;\"><a href=\"https:\/\/wardiz.org\/blog\/2017\/11\/06\/gearbox-oil-leak-part-1\/nismo-tramission-baffle\/\" rel=\"attachment wp-att-1142\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-1142 aligncenter\" alt=\"Nismo-tramission-baffle\" src=\"https:\/\/wardiz.org\/blog\/wp-content\/uploads\/2017\/11\/Nismo-tramission-baffle-401x500.jpg\" width=\"401\" height=\"500\" srcset=\"https:\/\/wardiz.org\/blog\/wp-content\/uploads\/2017\/11\/Nismo-tramission-baffle-401x500.jpg 401w, https:\/\/wardiz.org\/blog\/wp-content\/uploads\/2017\/11\/Nismo-tramission-baffle.jpg 500w\" sizes=\"auto, (max-width: 401px) 100vw, 401px\" \/><\/a><\/p>\n<p>So I started to think the R34 had similar issue.
