Your driving up a hill, top down on what turned out to be one of the best weekends for weather this summer. Your gearbox 'jumps' out of third gear. That funny it's never done that before.
Well the picture below tells a story, it's the mainshaft from the gearbox and yes it definitely needs to be one piece to work correctly.
I examined the shaft and it apears to be a stress crack that resulted from a manufacturing fault 32 years ago. it's been waiting that long to break!
Now i know i want to put a ford 5 speed in the car but i was going to leave that for at least another month. Not now the car is disabled. However i have sourced a gearbox off ebay and will be collecting it this week. Hope it is OK.
The design work for the gearbox interface plate is underway, the details will appear here shortly.
On another note before i broke the gearbox i started to test the effect different pump unleaded fuels have on performance. It was to early to get meaningful results but Shell super unleaded does give more power. Probably what sent the gearbox over the edge.
