3rd gear crunch, only when cold.
Discussion
The 3rd gear on my 97 MR2 grinds/ crunches when i try to change up or down into third but only when the box and engine are cold.
When i bought the car the box was find, no issues at all.
Shortly after buying it i replaced the clutch and gearbox oil at the same time.
Since then ive had the crunch.
Initially i used some cheap gear oil. I then tried some expensive fully sinth castrol and then, due to a drive shaft popping out when doing the cambelt, i had to replace it again (used more expensive castrol)
Short of an expensive gearbox rebuild, is there anything i can try to try and fix the issue?
Thank you.

Bleed the clutch. Check you are getting full pedal travel - i.e. full disengagement.
My dad says, if that was a problem it would happen on all gears.Is he wrong?
As somebody who has worked in the OEM Manual Transmission arena, and trained the 'experts' that the dealers go to when they can't figure stuff out my recommendation is always to check the oil level, bleed the clutch and check that the gear cables on FWD vehicles are correctly adjusted before undertaking any work on a transmission that works in a subpar way.

I've had the same issue with my Evo into 2nd when cold for ages. I tried Millers nanotech in the correct grade, which only made things worse. It now runs Redline GL4 75/90, which has greatly improved the shift generally. Worth a try for £50!
Ive heard that from others too!Will get some
