The 75-90 gear oil is not suitable for an LT77.Update on progress. i've now got the gearbox i want painted and have assembled the gear selector rear part. I have gone with the poly bushes which were easy enough to fit. It selects all the gears nicely although reverse gear can be selected too easily. it could be i haven't set the spring correctly. Can anyone offer advice on this? I have heard that you just need to 'clout it' over to the left but it selects nicely and there doesn't seem to be any 'lifting' of such to get it into reverse............
I am also going to use this comma oil in the box unless someone says don't. What came out was rather thick and brown/really dark red. I've read that a good 75/90 can be used. Is this ok?

Oh I see. One bolt higher on the left and lower on the right. Gearstick would then lean to the right to put it nearer to 3rd gear. Makes sense.
The 75-90 gear oil is not suitable for an LT77.
It will be very hard to select gears when the box is cold.
Redline MTL or Castrol Syntrans are what you need.
Those 2 mentioned aren't cheap!
I paid about £18/L but that was ten years ago. It's on ebay at £26.95 inc vat and delivery
I know you're spending out a lot of money at the moment with the gearbox and bits to fit it, but the MTL is definitely worth it
Just to add the box is designed for the thinner oils and if you use the 75-90 gear oil , in cold weather it can shear the drive to the oil pump in the gearboxI paid about £18/L but that was ten years ago. It's on ebay at £26.95 inc vat and delivery

What differences did you observe, when moving to the Syntrans from the 0w20?t is only recently I have been using Syntrans.
I was looking at oils, gearbox drain imminent. So would Syntrans be Ok for a 4 cylinder too? Castrol GTX SAE 20 says the Book.
