6-Speed Carib box notchy

[petercad]

Got a 6-speed Carib, and notice that the box is notchy and hard to shift when cold. What is the recommended fluid for it and is there another alternative that I can use for hard shifting when cold?

auto trans fluid (atf) for 1000-2000k's helps then back to good quality manual stuff (redline)

[petercad]

Cheers for that. Will try it this weekend. What is the redline stuff - just a 75w/90 manual trans oil?

[escortman]

just use a good weight engine oil

from taking two or three for a spin, the 6spd seemed to be a lot notchier than the 5 spd... not sure if they had just been abused/mis-used or not, but the 6 spd manual in my old runx was far notchier than the 5 spd in the normal corolla

[petercad]

Yep, I agree, the 5-speeds are smoother. Just that this one seems worse than the other 6-speed I had 2 years ago with similar k's on it. What weight engine oil do you suggest, or just any one that is good quality.

[Mr Revhead]

engine oil? not what id use....

[Dell'Orto]

Would be far too thin! What does the factory recommend, 75w90 or something? Plus engine oils aren't EP rated.

[petercad]

It has Penrite 75w90 in it now and its a little better. Still not as I remember them though. Whats the actual recommended lube for them?

Try the redline oil

It actually makes a difference over other oils!
