I’ve seen the issue you describe when the problem doesn’t go away after checking the hydraulics or electrical. If a “long” spring is where one of the short ones should be, it will coil bind and prevent the clutch from moving far enough to contact the brake ring fully. It only takes one spring in the wrong place to hold back the clutch sufficiently to prevent full contact with the brake ring. It may hold intermittently but will slip under load, or acceleration. Be sure to check your springs for compressed length since they may be the same length otherwise and it’s hard to tell a “short” one from a “long” one.<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Arial","sans-serif";color:black'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-family:"Arial","sans-serif";color:black'>Mike Hado<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Arial","sans-serif";color:black'>. <o:p></o:p></span></p><p class=MsoNormal><a name="_MailEndCompose"><span style='font-family:"Arial","sans-serif";color:black'><o:p> </o:p></span></a></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> Fot [mailto:fot-bounces@autox.team.net] <b>On Behalf Of </b>Henry A.

I thought all the pressure producing bits looked good so mostly left them alone. I did the pressure test when I got it all back together and it was close to where it was supposed to be. I drove the car once and it seemed to work, drove it again and it dropped into overdrive whenever I lifted off the gas and dropped out again when power was re applied. This is pretty much what the thing was doing when I started the project and I'm sure was the reason for my slower than they should have been lap times at the Cup! <o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Calibri","sans-serif";color:black'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Calibri","sans-serif";color:black'>Any suggestions on what to do next? <o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Calibri","sans-serif";color:black'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Calibri","sans-serif";color:black'>Cheers, Henry Morrison<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Calibri","sans-serif";color:black'><o:p> </o:p></span></p></div><div class=MsoNormal align=center style='text-align:center'><hr size=3 width="98%" align=center></div><div id=divRplyFwdMsg><p class=MsoNormal><b><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:black'>From:</span></b><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:black'> Fot <fot-bounces@autox.team.net> on behalf of Glenn Franco via Fot <fot@autox.team.net><br><b>Sent:</b> Thursday, September 21, 2023 2:57 PM<br><b>To:</b> Nick Black <vintagenick42@yahoo.com><br><b>Cc:</b> Joe Boruch <jaboruch@yahoo.com>; FOT Triumph <fot@autox.team.net><br><b>Subject:</b> Re: [Fot] A-type OD leaks</span> <o:p></o:p></p><div><p class=MsoNormal> <o:p></o:p></p></div></div><div><div><div><p class=MsoNormal>I have to chime in on issues with the A type overdrive.

You basically need at least yourself and a helper to put it together. I probably did 10-12 of these 2 or more years ago. First time we did one we split the adapter plate pulling the O/D on to the transmission. Unfortunately it was welded back together and the repair was a weak spot. If you force the O/D onto the trans when pulling it back together with the 2 nuts on the O/D studs it will break or bend the plate.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>The fasteners (6) that hold the plate to the back of the transmission are drilled for safety wire. I used stainless safety wire on those after torquing. Make sure you repeat the way the wire is routed through the bolt heads. I had a couple transmissions leak because I didn't follow the routing properly. I mistakenly routed some of the wire near the base of the plate fouling the gasket which resulted in an embarrassing 3 comebacks on one transmission due to leaks.<o:p></o:p></p></div><div><p class=MsoNormal>Took awhile to figure it out, dumb mistake.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Glenn 74 TR6 Restored, 68 TR250 Frame Off in Progress, 73 BMW 2002 <o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div></div><p class=MsoNormal><o:p> </o:p></p><div><div><p class=MsoNormal>On Thu, Sep 21, 2023 at 4:04 PM Nick Black via Fot <<a href="mailto:fot@autox.team.net">fot@autox.team.net</a>> wrote:<o:p></o:p></p></div><blockquote style='border:none;border-left:solid #CCCCCC 1.0pt;padding:0in 0in 0in 6.0pt;margin-left:4.8pt;margin-right:0in'><div><p class=MsoNormal>Joe <o:p></o:p></p><div><p class=MsoNormal>I agree, it’s the bolts that hold the od plate to the transmission.
