    GT6 GT6 Stiff Gear Selection

    Hi guys, I've got a GT6 MK3 1971. I was having clutch and gearshift issues. It was creeping forward with the clutch down and sometimes failed to engage at all. The car had a recent rebuild when I bought it, but I think a few problems had been missed, or began as a result of said rebuild. I...

    For Sale 72 TR6 clutch and transmission

    I decided to replace my 72 TR6 4-speed transmission with the Miata 5-speed. The TR6 clutch and transmission worked flawlessly. No mechanical issues with it, I just travel longer distances in my car and needed the five speed for highway use. Located in Collingwood Ontario, can be brought to...

    The Infamous 3-synchro MGB Transmissio

    A Tale of Transmissive Tutelage Submitted by @DrEntropy This story takes place a few decades back, when we could find MG’s largely un-rusted and for affordable amounts of money. To be accurate it was late in 1972. As a Sergeant in the US Air Force and married to my college heart-throb for a...

    MGB Gearbox Selector Shaft Tensioning

    There are three screws just behind the bell housing which bear on a spring and ball to put tension on the operating Rods. Does anyone know how to manover the gearbox into a position in order to remove these bolts so that I can increase the tension on these springs with the introduction of a...

    TR2/3/3A Gearbox Countershaft Shim?

    I read in the Green County Triumph gearbox rebuild guide that you can place a shim next to the distance piece to decrease countershaft end float so that it's between 6-10 mils (7-12 mils in the later manual). Is this really acceptable? It just seems like a 3-mil shim would wear over time and...

    Hi All, I'm a new member that is neck deep in the restoration of my late father's 1959 TR3A. Currently I'm working on rebuilding the 3-synchro gearbox, and am hoping to get some advice (mostly on acceptable wear) due to the fact that this is my first transmission rebuild. I would like to...

    TR4/4A TR4 A Type Overdrive Part mixup

    After finding that mainshaft 3rd lost a tooth into layshaft 2nd and mainshaft 2nd, I decided to have my friend the mechanic overhaul the gearbox and overdrive. I decided to replace all bearings with the best I could find. In other words no no-name ones. Bought them from Rimmers, TRF and a local...

    Transmission rear bush for drive shaft yoke - no joke!

    Hello Everyone, I am new to this forum, and need some help, please. I purchased a 69 Sprite recently and had some gearbox issues. So I took the gearbox out for a 'quick' re-build. Everything is fine apart from the rear bushing where the propshaft yoke is located. There was some play in the old...

    TR2/3/3A TR3 Gearbox Dipstick Question on oil level

    Today, I drained my TR3 non-overdrive gearbox. I refilled it with 1.8 pints of oil (approx 3.5 cups). After a short drive I checked the level with the gearbox dipstick and nothing registered. There was no leak. Do I keep it at 1.8 pints or do I fill it until it reads on the dipstick? When I...

The car has 54,715 original miles on, I was told when I bought the car many years ago that the transmission had a recent rebuild. The car...
