BarryClark Posted July 25 Report Share Posted July 25 I am a newbie on here. I have a TR6 where the overdrive doesn't work . I know is=t may be the solenoid , but as they are £200 on EBAY I am thinking of doing an exchange unit. On here for sale is a J type no 312377R which is listed for a stag. On Rimmers they supply for the TR6 a 313242R . My question is are hey both compatible with the TR6 gearbox? Many thanks. Barry. Link to comment Share on other sites More sharing options...
Pete Lewis Posted July 25 Report Share Posted July 25 all base J types are pretty much all the same basics overdrive repairs sheffield list J type sol as £120https://www.overdrive-repairs.co.uk/product/type-solenoid-new/ or james paddock James Paddock Limited - Triumph Stag, Spitfire, TR6, TR7, GT6, Vitesse, Herald Parts and Spares Specialists. OVERDRIVE SOLENOID J TYPE (NKC41) have you removed the solenoid ??? they do wear our some simple rings you need a thin 1" af spanner to loosen the unit do not get grips on the case you can wreck it easy. give the thing a shake the spool inside should rattle ( i call it the maracas test) in the end of the sol. is a small 10mm circlip remove and get the spool valve to shake /tap out. it must move freely . its on this the 0 rings give up its worth a look many sell the spanner for £10 ish and still not easy to use on the car easy on a bench on car sol. removal will loose a cupfull of oil which needs topping up on refitting its well worth a look at this its often the problem and costs pennies to solve ques. what was wrong with the OD ??? have you ever cleaned the filter pad ???

BarryClark Posted July 26 Author Report Share Posted July 26 HI Pete, Thanks for the reply. It just doesn't engage . Have seen the tool to remove the solenoid for about £10- £12 . I will probably try that route, and see if I can get it working , it's obviously the cheapest route . Haven't cleaned the filter pad so will do that. Regards. Barry.

johny Posted July 26 Report Share Posted July 26 The solenoid is definitely not operating? Before dismantling anything you can measure the current draw to check the electrics as a high proportion of OD failures are down to this side of things..

Pete Lewis Posted July 26 Report Share Posted July 26 Agree you must stick a small bulb or test meter on the feed with to the solenoid , as said it could be fine but electrics have let go. culprits being inhibitor switch and its setting/adjustment , followed by wires down the gear stick ,column stalks tend to be ok dont touch the solenoid till you have proved the 12v supply to it Pete Link to comment Share on other sites More sharing options...
