carld Posted October 17, 2016 Report Share Posted October 17, 2016 Apologies I cant find my original thread, for sometime now I have had issues with no drive in second gear, unfortunately it was intermittent but getting less so, so I bit the bullet and took the gearbox out this weekend Removing the top cover all gears and rings look to the untrained eye, appear to be in very good health, very little swarf on the magnetic drain plug, the gearbox number is G565137, however this has been over stamped and I cant make out all of the original numbers, below is another stamp 23 L 66, I assume this is the year I am now not sure what this gearbox is from, a saloon perhaps?, the solenoid is also mounted vertically, which in partly is what has led me to think this isnt the original gearbox to the car. Question is where do I go from here, take the gearbox and overdrive to a specialist, I have been recommended to Overdrive repair specialists in Sheffield All thoughts welcome and anyone have a reference guide to gearbox numbers Cheers Carl Quote Link to post Share on other sites

Gary Flinn Posted October 17, 2016 Report Share Posted October 17, 2016 Hi Carl You have an 'A' Type Overdrive by the looks of it which is correct for most TR's up to the later TR6's which had a 'J' Type overdrive with a horizontal Solenoid mounting. I don't really know to much about what could be causing the intermittent drive in 2nd gear though, does it only happen in Overdrive 2nd or normal, if only Overdrive this could be the problem? With regards to the type of Gearbox, could it be a TR4A Box maybe? I will have a word with John Gregory and see what he reckons, he knows a lot about Triumph Gearboxes.

carld Posted October 17, 2016 Author Report Share Posted October 17, 2016 Cheers Gary, as soon as I posted, I had realised that of curse I should have an a type overdrive, too much time working on friends and the 6's we bought and sold years ago.. I know John of course, but haven't seen him for some time and would welcome his advice, thanks for the link Problem occurred in 2nd, it felt as if the overdrive was trying to come without being asked to and therefore no drive, no issues in 1st, 3rd or 4th?

carld Posted October 17, 2016 Author Report Share Posted October 17, 2016 Cheers mate, 911 going to Le Mans, so would like to take the 5 to Spa, or though it's tempting to take the 911 to buzz around with SPARKY Quote Link to post Share on other sites

carld Posted November 4, 2016 Author Report Share Posted November 4, 2016 Met with Pete at ODRS this morning, took it all apart before my very eyes, gearbox all good, OD a complete mess, he was very surprised I was getting any drive at all! Going to have the stag mod on the gearbox and complete overhaul on the OD. Thanks for all the help/advice, top operation, mine is number 11 in the waiting list of triumph gearboxes/overdrives.
