PandO Posted June 27, 2017 Report Share Posted June 27, 2017 My overdrive has stopped working in any gear - relays click when column switch is operated in 2 3 or 4 gear. Does not appear to leak oil and was recently topped up. It has tried to engage and it seems to get stuck between Overdrive and non-overdrive. When this happens when cruising and I take my foot of the throttle I can see the revs slowly dying whilst the speed remains much the same - much like freewheeling. Any ideas what could cause this - is it going to be an overdrive strip down? Quote Link to post Share on other sites
RogerH Posted June 27, 2017 Report Share Posted June 27, 2017 Hi, have a look at this post. Sounds a little similar http://www.tr-register.co.uk/forums/index.php?/topic/62022-newn-on-me/ Roger Quote Link to post Share on other sites
Coops Posted February 2, 2023 Report Share Posted February 2, 2023 Hi, I had this freewheeling, turned out to be the cone clutch in the OD unit. Quote Link to post Share on other sites
Mike C Posted February 2, 2023 Report Share Posted February 2, 2023 I assume the oil level is correct, personally I'd check it again. If you have a type A -check the operating lever on the side of the O/D is moving and properly adjusted. Note you should hear clicks from two relays when you engage the O/D- one from the passenger side of the engine bay and one from the O/D solenoid. Quote Link to post Share on other sites
harlequin Posted February 2, 2023 Report Share Posted February 2, 2023 I had this once as I went into an underpass on the Brussels ring road. I went into overdrive and nothing no drive ar all I came out of overdrive still nothing, we ended up almost at a stop in the bottom of the underpass and the drive returned and we got going again with traffic swerving around us. I tried the overdrive again on a quiet side road and no problem. I never did get to the bottom of it as I sold the car shortly after. George Quote Link to post Share on other sites
Drewmotty Posted February 2, 2023 Report Share Posted February 2, 2023 (edited) Sounds like the overdrive face on the cone clutch is slipping so the drive will continue at 1:1 through the uni directional clutch but freewheel on the overrun.
