3rd gear crunch, only when cold.

[Benbay001]

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?

Deffinately the correct grade oil.
Ill try bleeding the clutch. (probably next weekend now) and get back to you.
Would a clutch with air feel any different?

My biggest worry is selling it.
Which will be at the end of this year.
Im happy to live with the crunch.
But i worry that if someone test drives it the crunch will be enough to put them off buying. Would like to get it sorted.
Whats the likely cost of a rebuild?

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
