Sticky maybe??

AJ, where did you get that info from? The red maintainance manual or some workshop manual?

[AlfaJack]

The top two pages are from the red owners manual which should come with the car, I think one book covers all 92-95 155s so you may be able to get hold of one fairly easily

Thank you for helping.
I wil use Castrol SMX-S in my gear box , and SAF-XO on the rear diff.

I plan to change the oil in the rear diff, because it is not known when was last changed (if it is changed at all). I will use Motul Gear 300 -> link. Does someone use this oil for rear diff and/or gearbox? What oil did you use?

You probably changed all the oils long time ago ...I've used Gear 300 too for my rear diff 3 years ago when it was rebuilt/refurbished. My gearbox/central diff on the other hand was dis- and reassembled 2 weeks ago and I've bought Motul HD 80w90 for that.
