What oil to use to stop gear crunching?

**spetz** · 15-01-2008 04:38 PM

On my run around (1990 2.0L Camry)
3rd gear crunches a lot, to the extent I have to double clutch to downshift and go into 3rd slowly
Now, I realise that it'll never go away, but is there any oil to at least make it a bit better?
I have ATF Dextron III in it now which is recommended for that car
It crunches less when it's cold/more when hot
So, should I get thicker oil? Or just leave what's in it and deal with it?

pardon?
your using atf dexron 3?
that's for autos? who recommended that?

dexron 3 is Auto box oil.
Most manuals use a thicker oil like 75-85.

Drain that fluid and put Toyota MTF in there (buy it from a toyota dealer), and if it still crunches then its likely the Synchros are gone and need replacing.

flush it out twice though.

The factory recommended 'oil' for at least some manual boxes is ATF.

i heard putting engine oil is good.
my mate put mobil1 10w-30 in his b16a civic GB and it shifts like a dream

how many k's on the current clutch ?

**Klayemore** · 15-01-2008 08:02 PM

Check ur synchros. Mine are gone and crunch like ****. It's fun.

+1 to some manual boxes needing ATF.

If it crunches worse when hot i would be putting all my money on your synchros being shagged and changing the oil wont do diddly-squat.
