re-hiker Posted April 30, 2014 Report Share Posted April 30, 2014 good morning Coolie do you mean you have a TR 4 Gearbox with a J Type Overdrive and you need a Gear Change Lever for the TR Gearbox? What Chassis and what Gearbox Number? Do you need the Wiring Diagramm to install the Electric Part of the Overdrive? Is your Car LHD or RHD? Sorry, but a few Details needed to help you. regards re-hiker Quote Link to post Share on other sites

stuart Posted May 7, 2014 Report Share Posted May 7, 2014 Regarding choice of gear stick, it depends on what top cover is fitted, if its a TR4 top cover then you will need a TR4 gear stick and cap and the long bolt that goes through it to secure it. If its a saloon or TR6 top cover then you will need the later type of gear stick and cap that is located by two studs with lock nuts.Dont forget you will need an anti rattle spring and pin. FWIW the serial number starting with GR on the box means its a reconditioned box. Stuart. Quote Link to post Share on other sites
Lebro Posted May 7, 2014 Report Share Posted May 7, 2014 Re Stuart's post above, I have an O/D Saloon gearbox in my '3 (from a 1972 T2000), & I fitted the original 3 gear lever & cap with the through bolt. I probably drilled out the side tapped holes to take it (cant remember doing so, but must have) Bob. Quote Link to post Share on other sites
Dave McDonald Posted May 7, 2014 Report Share Posted May 7, 2014 Bob I don't think you need to drill out the side tapped holes. The studs/lock nuts with the later models are 5/16" unf. The long through bolts on the earlier models are 1/4" unf and will pass through the later stud holes. I have a TR4 gearlever with the long through bolt on my TR6 race car gearbox and have not drilled it out and don't have problems with it. Dave McD Quote Link to post Share on other sites

Lebro Posted May 8, 2014 Report Share Posted May 8, 2014 Dave. Yes that sounds right, I though I had not drilled through -should have trusted my memory ! Quote Link to post Share on other sites

Appreciate your response; so if I fit my TR4a top cover (including gearstick etc), will this be ok on a TR6 box? Many thanks David Quote Link to post Share on other sites
Nobbyc Posted July 16, 2019 Report Share Posted July 16, 2019 i used the saloon j type box and top cover. just shortened the gear stick to suit and wired the o/d to work from the gear knob switch. Quote Link to post Share on other sites
