tr5sean Posted July 21, 2015 Report Share Posted July 21, 2015 The overdrive on my TR5 is messing about!! When selected it takes a couple of seconds to engage runs ok whilst driving steadily but the overdrive cuts out when I accelerate hard. Easing off the throttle often allows it to cut back in (a bit like kicking up and down in an automatic) but it will never re-engage at 70mph. I have checked the oil level all ok and also the solenoid which clicks in and out when tested ignition on, 4th gear selected. any ideas?? Sean Quote Link to post Share on other sites
alec Posted July 21, 2015 Report Share Posted July 21, 2015 Hi Sean Might be a long shot but:- Have owned my TR6 for 30years plus. The gearbox & overdrive were reconditioned 6 years ago & has covered 35,000 miles since no problems 105,000 miles on the clock. Last year on our way to euro tunnel on the M2 the overdrive suddenly cut out then after a few seconds cut back in this continued so left the overdrive off. Early part of this year did I get the car on hoist & found the earth connection, crimp lug, only just making connection i.e very loose, the earth link to gear box was replaced with new & problem resolved. Worth a check & clean both terminals. Alec Quote Link to post Share on other sites
tr5sean Posted July 21, 2015 Author Report Share Posted July 21, 2015 Thank you very much Alec I will double check although all looked good when I first looked at it on the hoist today! sean Quote Link to post Share on other sites
ctc77965o Posted July 22, 2015 Report Share Posted July 22, 2015 Sounds like low oil pressure inside the OD Quote Link to post Share on other sites
Speed Posted July 22, 2015 Report Share Posted July 22, 2015 Sounds like low oil pressure inside the OD I would think same as well, hope you sort it Quote Link to post Share on other sites
Drewmotty Posted July 22, 2015 Report Share Posted July 22, 2015 The cone clutch must be slipping. It could be caused by low oil pressure or the wrong type of oil in the overdrive or it could just be worn. Quote Link to post Share on other sites
