Conundrum <br>Hi Michael,<br><br>I rebuilt the gearbox and O/D probably =
about 7-8 years or so ago. I've probably put close to 10K miles on it since=
, but not too many since I moved to the Central Valley. For the last few =
years it's been mostly short and day trips every month or two so, it's been=
mostly sedentary. A few months ago I took it out for a spin and noticed =
the O/D wouldn't engage at first but would start working normally after =
maybe 20 minutes of driving. In subsequent runs it's more not engaging, =
until a few days ago I'd decided I would likely have to pull the gearbox =
and O/D, but had to pull it out to get it off the QuickJack underneath it =
and, to my surprise it started to work OK again after 15-20 miles.<br><br>I=
rebuilt the O/D myself, and I think I did OK except I may not have gotten =
the planetary gears depth exactly right; I didn't have a selection of =
thrust washers to try so I just put the existing one back in. The only =
thing I changed out was the thrust ring bearing, which might have been a =
different width. The unit did have a very slight vibration, barely =
noticeable through the floorboards but otherwise operated perfectly. Now, =
when it works, it seems fine. When I rebuilt the gearbox the rearmost =
thrust washer was whacked (see pic), but of course I replaced it (how that =
could happen and why the O/D worked is another mystery). I couldn't get the=
GB and O/D to mate up so I took them to BCS where David Nock got them =
together and set the operating shaft lift. Besides trying a new relay at =
Tom Monaco's suggestion I haven't done anything else to it.<br><br>Only =
thing I can guess is maybe the lever that the solenoid lifts to turn the =
valve operating cam maybe slips sometimes and not others.=

<div class=3D"BodyFragment">
<div class=3D"PlainText">Listers,<br><br>I =
have a problem with my BJ8's overdrive that defies conventional logic: =
<br>The O/D will not engage when the drivetrain is cold, but begins to =
<br>function more-or-less normally as the drivetrain gets fully heated-up =
<br>(15-20m on a warm day). I've checked the functioning of the =
electricals; <br>i.e. when not running I can a) disconnect the coil ground =
so as not to <br>fry the Pertonix Ignitor, b) place the gearbox in 3rd or =
4th and c) <br>close either, or both, the dash switch and/or the switch on =
the shift <br>knob --they're wired in parallel so either one will engage =
the O/D, but <br>both need to be in off/open condition to disengage--and I =
can hear the <br>solenoid click firmly (this pretty much rules out the =
switches). I have <br>already replaced the scuttle relay to no effect (I =
have had them get <br>flaky). AFAIK, the throttle/'kickdown' switch only =
comes into play when <br>disengaging, and seems to work when the O/D does =
engage.<br><br>My thinking is, if the pump is failed or failing the O/D =
might work when <br>the fluid is cold but cease to function as the fluid =
heats up and thins <br>out (I've used Redline MT-90 successfully for over =
100K miles or more; <br>it's equivalent to 50wt engine oil). But, the O/D =
not engaging when cold <br>(somewhat) refutes this theory. If the outlet =
check valve on the pump <br>was somehow boogered I would expect either a) =
cold function only, or b) <br>no function at all. Ditto the solenoid; I'd =
expect it to get flakey when <br>hot and it does 'click' reliably (when =
cold). I can imagine the lever on <br>the operating cam slipping, but =
wouldn't expect that to vary with <br>temperature (or to work at all, =
actually). Actuating shaft lift was <br>correctly set at rebuild. I do have=
a DWM 'uprated' accumulator <br>installed, and the O/D engages within 2 =
seconds when it functions.<br><br>Anyone had this condition, or have a =
theory as to why it behaves this <br>way? Next step would be to remove the =
console and confirm I have good <br>oil pressure (but if I do, then what?).=
