I recently had my 1981 FJ40's gearbox and clutch replaced as it stopped shifting while the engine was running. The mechanic said the gearbox was run dry. After less than 500 km, I have the same problem again - it shifts fine while the engine is not running (you can run through all the gears), but once the engine is running I can't shift at all into any gears. Any suggestions for the fix? Cheers.
