I recently replaced my clutch/pressure plate assembly and used the opportunity to replace gearbox front and rear seals, as well as completely disassemble and rebuild the top cover. With everything back together, I'm now noticing that the car slips out of 3rd gear (and into neutral) when throttle balances forces. This is definitely a new issue and 3rd gear is the only gear that this is happening. I did not touch the gearbox itself as everything looked good visually. All I can think of is that I didn't get the detent ball and spring assembled properly, or the spring itself was weakened in the process. Am I overlooking any other causes?
