hi, i have 1st hand experience of this, my main dealer replaced oil with wrong grade, too thick. real bad when cold. re changed oil foc, better but not right, flushed box and replaced oil once more, perfect ! get it sorted asap thick oil is not good when cold damage will be done. a local garage destroyed an isuzu gbox for me as a direct result of this. take my word for it dont trust them if they wont put their hands up to a mistake, cheaper in long run to bite the bullet if necessary and pay to change oil to correct viscosity if necessary. luckily my main dealer were honest and went out of their way to get things perfect for me. restored my faith completely. well done nunns mitsubishi of grimsby!! same principles apply to all makes, obviously.
