The first four gears are almost identical to the TR gearbox. 5th is very deep. The W-58 shifts smoothly and there is little chance of selecting the wrong gear as long as you have a gentle touch on the shifter. Mine was rebuilt before I installed it, yet the third gear synchro is a little weak. Using Redline MT 90.</div><div>I have been told that there are upgrades for both the synchros and fifth gear, but so far I know nothing about them or where to source them.</div><div>The clutch disc that comes with the kit is a bit weak for an uprated engine. Updated competition clutches are available from both Spec and California Clutch.</div><div>Installation of the kit is straightforward and relatively simple.</div><div>Regards,</div><div>Phil <br><br><div dir="ltr">Sent from my iPhone</div><div dir="ltr"><br><blockquote type="cite">On Jul 31, 2023, at 7:43 AM, Erik Jacobsen via Fot <fot@autox.team.net> wrote:<br><br></blockquote></div><blockquote type="cite"><div dir="ltr"><div class="yahoo-style-wrap" style="font-family:Helvetica Neue, Helvetica, Arial, sans-serif;font-size:16px;"><div dir="ltr" data-setdir="false">FoT,</div><div dir="ltr" data-setdir="false">After the post-race work on the TR3, I found that the A type O/D gearbox has a rather significant crack in the case near the bell housing. It's been welded before, so additional welding is not looking promising. Like most A type units, it leaks like a sieve and this one seems to only intermittently engage. Therefore, I'm considering going to a 5-speed set up. Any experience with either the HVDA (Toyota based) or the Vitesse (Miata based) units? I'm a fan of originality, but I'm also tired of fighting the fun of O/D units and the fact that getting one properly rebuilt in the US seems to be very difficult.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Thanks!</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Jake Jacobsen</div></div><div><0730231557.jpg></div><div><0730231558.jpg></div><span>_______________________________________________</span><br><span>fot@autox.team.net</span><br><span></span><br><span>http://www.fot-racing.com</span><br><span></span><br><span>Donate: http://www.team.net/donate.html</span><br><span>Archive: http://autox.team.net/archive http://www.team.net/pipermail/fot</span><br><span>Unsubscribe/Manage: http://autox.team.net/mailman/options/fot/vfracing@aol.com</span><br><span></span><br><span></span><br></div></blockquote></div></body></html>
