1) You're shifting into reverse too fast or too soon 2) Car is moving when you select reverse 3) Wrong oil in gearbox 4) Gearbox oil is very cold 5) Clutch misadjusted 6) Friction disc binding on splinesKeeping the pedal down, select 4th, then neutral again, then try reverse. Does it crunch now?
If you are selecting R from N, then the gears are still turning when you go into R. Try shifting into any other gear first, then select R without releasing the clutch.
This grinding is caused by too having thick of an oil in the transmission. The causes of thickness can be the oil itself, or a very cold climate.
Does the clutch 'start engaging' when still very near the floor?
I've found its mainly when the gearbox has weight on it. When i let the handbreak out and roll forward a little it seems to slip in. (This is with the clutch in) I was just wondering is there anyway i can fix it so it goes straight in no mucking around.

You have to push in the clutch before selecting reverse.
Yeah thanks for the tip very helpfull.
I think you're stuck! Every single Toyota I have ever had has done this. I never tried to look for a fix because some of them have gone well over
200,000 miles.Try rolling the car forward a bit before shifting into reverse. This has always worked for me. Try shifting into reverse gently and if it doesn't go right off the bat, go into 1st and roll about an inch and try again. Usually works for me.

I already gave you one idea:
"Keeping the pedal down, select 4th, then neutral again, then try reverse. Does it crunch now?"
Ok, that's not a lot, I wonder if it's getting fully released?...you might try ramming it hard on the floor, wait for a few seconds, then see if it does it.
I bled the clutch and adjusted the clutch lever itself and it seems to be working alot better.
Yes, looks like the clutch wasn't getting fully released doesn't it?...
