Bongo Fury

To be more clear... when I start with a cold engine the change up through the gears is taking longer than usual and the response to the accelerator seems slower too, Then a few minutes later it suddenly corrects with a burst of acceleration. After that it is pretty much as usual but sometimes is again a bit slow in changing gear. My first thought was fuel blockage but that usually means low rpm whereas I can reach 3000 and more rpm ok.

I dont understand how the auto works, could someone explain. Can the state of the oil in the gearbox affect as above?

if you don't drive at 2,000 rpm or less till the engine and gearbox warm up ( engine temp gauge @ 11 oclock) then gearbox wont change gears properly
