If you ask Holden about changing the oil,they will tell you the oil in it is for the life of the gearbox and is an unserviceable item!!!!!!!!!!!!!!!!!You can't change just the oil, unfortunately I've been told from Holden that the gearbox has to be removed to change the oil.
I replaced mine in the ute with Penrite MGO 70 which Penrite now call PRO GEAR 70W-75 Full Syn.The boys on JC put me onto it and honestly havent looked back.It comes in 2.5lt bottles and you will need 4.4lt.Drain the original out via the bottom drain plug while its warm, I let mine drain out overnight and then refilled it with 4.4litres thru the reverse light switch using a hand pump which screwed on top of the penrite bottle.Easy to pump unlike heavy gear oil and the difference is amazing,but compared to say a japanese gearbox you would swear the T56 is from your grand fathers tractor
Tinsnips hit the nail on the head with his description of the gearbox
I take it that it is still under warranty,run it past the service guys next and see what they reccomend you do,but dont expect them to put anything other than the DEX111 in it ,even if you give them an alternative fluid supplied by you.If you dont feel confident in doing the job ring around and get quotes from a workshop that specializes in manual gearbox,s.
I,msure there are quite a few boys on here down your way who could give you the thumbs up on a few good specialist and reccomend their work, and short shifting wont do any harm,I sometimes go from 1st,3rd,5th with no labouring what so ever,its amazing the torque these 6lt engines put out
Cheers mate
