Speaking of spinning the OD backwards, which it won’t do, what happens if you spin the car while overdrive is engaged? Probably my biggest concern for running one of these in a race car... I was thinking I’d use it on track and maybe autocross, but I think that is ill advised now that I bring up that question. Has anyone ever spun and rolled backwards, with OD engaged?<div><br></div><div>Dave G<br><br><br><a href="https://overview.mail.yahoo.com/?.src=iOS">Sent from Yahoo Mail for iPhone</a><br><br><p class="yahoo-quoted-begin" style="font-size: 15px; color: #715FFA; padding-top: 15px; margin-top: 0">On Tuesday, December 24, 2019, 12:47 PM, Greg Blake <gblake58tr3@icloud.com> wrote:</p><blockquote class="iosymail"><div id="yiv0957845862"><div>If this is for a race car, you might consider shiming the accumulator spring to get closer to 500psi. <br clear="none"><br clear="none"><div dir="ltr">Sent from my iPhone</div><div dir="ltr"><br clear="none"><blockquote type="cite">On Dec 24, 2019, at 10:51 AM, David Gott via Fot <fot@autox.team.net> wrote:<br clear="none"><br clear="none"></blockquote></div><blockquote type="cite"><div dir="ltr">
I was able to test my overdrive by chucking a 1/2” electric drill on the input shaft and turning the whole transmission. (Make sure to spin the right direction!). Pretty sure I used 4th gear.

<div dir="ltr">I have tested overdrives like this for years. My drive motor only spins in one direction, which makes sure the output shaft only spins in the same direction the shaft would be spinning when the car is driven in a forward speed. Therefore, I don't know what would happen if you spun it in the wrong direction.</div><div dir="ltr"><br clear="none"></div><div dir="ltr">Jack<br clear="none"></div><div><br clear="none"></div>
