FD 2nd gear grinding
 
less than 70K on the trans, but slightly crunchy going into second and a bit less going into third.

How much of a difference will good synthetic oil make?

Thanks!

You didn't say what year.
IIRC, 93's, especially early production 93s, were a little notchy from 1st to 2nd right from the factory. Synthetic would help that some, but didn't it make it go away. I know, I tried.
If it's "crunchy" and if you have similar symptoms from 2nd to 3rd, I start suspecting worn synchros. It's relatively easy and inexpensive to change out the transmission gear oil, but it's not likely to heal the synchros. So not much difference should be expected.

Is it hard to get into 1st, possible clutch release issues causing this?

it definitely gets better when it warms up, I think I will try some good synthetic...

Hi,

Sorry for posting in an old thread but I am having a similar issue to this, hard to get into 2nd, especially when the car is cold.

Did you manage to resolve the issue? My car has a B&M short shift and I wasn't sure if this was causing an issue?

Thanks in advance,
David

Doubt the SS would have anything to do with it. How old is the gear oil? Try a good synthetic if it's been a while. I recommend 75w90 in say Redline or NEO HD

Try a new shifter and you might want to replace your shift select spindle as well
