nigelcurry Posted November 20, 2020 Report Share Posted November 20, 2020 Hi all I want to get to the o/d solenoid,as I have started to strip the seats and carpets how much further do I need to go to unearth the solenoid to visually check the solenoid and wiring for the o/d unit.I hope to be able to expose the top of the o/d unit to see where everything is but don’t know if that’s possible! stay safe nige Quote Link to post Share on other sites
Waldi Posted November 20, 2020 Report Share Posted November 20, 2020 Hi Nigel, it is best to remove the GB tunnel, so you also have proper access to the switches on top of the GB. Also, adjusting the solenoid (A-type I assume) is easier. Waldi Quote Link to post Share on other sites
saffrontr Posted November 20, 2020 Report Share Posted November 20, 2020 Hi Nigel, As Waldi has said above best to remove the gearbox tunnel, that will give you access to the wiring, solenoid and switches. If you don't want to do that there is a plate on the tunnel for access to the solenoid however removing that will not provide access to anything else. Derek Quote Link to post Share on other sites
nigelcurry Posted November 20, 2020 Author Report Share Posted November 20, 2020 Thanks guys because the car is a 72 CP model I think it may be a J type o/d,will the access route be the same! I hope it is as your pics and advice is just what I was after nige Quote Link to post Share on other sites
saffrontr Posted November 20, 2020 Report Share Posted November 20, 2020 (edited) Nige, A 72CP should have an A type as per photo. The J type came in for the CR and CF series albeit many earlier TR6's have been retrofitted with the J type. If you have a look under your car and see a circular brass plug then you have the A Type - see image from the web showing the brass plug Derek Edited November 20, 2020 by saffrontr Quote Link to post Share on other sites
nigelcurry Posted November 20, 2020 Author Report Share Posted November 20, 2020 That’s the very one! great ,now I know where to go next thanks guys Nige Quote Link to post Share on other sites
Mike C Posted November 20, 2020 Report Share Posted November 20, 2020 OK you have an A type. Basically check the adjustment using a drill bit in the locking point on the other side of the operating shaft- see the Brown Bible & check you are getting an electrical signal to the solenoid with the gear selector in 2nd, 3rd and 4th, with the G/B interlocks preventing a signal in 1st and reverse. The wiring to the OD causes most A type problems- I fitted a Landrover "OD on" light to mine to confirm while driving that it's getting the electrical signal when it should.
