Hi forum,

Sorry if there's a how-to guide for uninstalling/reinstalling a transmission for an Omega B somewhere (I searched in vain) but that's precisely what I require help with...
More specifically, if someone could point me in the direction of a guide (or perhaps give me a write-up of their own) I would be very grateful.

The vehicle is a 1996 Omega B, 2.5L (X25XE). The donor transmission comes from a '94 Omega B (X30XE).

I would like to know;
-What tools are required (incl. axle stands, oil trays etc)
-What oils/lubes are required
-Pre-process preparation
-Post-process engine burn-in or restrictions
--Perhaps a step-by-step guide of the process

If these cannot be met or I'm not confident I can perform the work myself, I will get it done professionally.
Being a financially-strapped student, I would like to save as much money as possible, so any help would be appreciated.

Thanks.

firstly why are you swapping what is wrong with the old box???
secondly are you swapping auto for auto? manual to manual ?

Auto for Auto, and swapping due to a transmission issue (often hangs in the transmission between the first and second gear, throwing up the diagnostic fault 'Automatic Gearbox')

If you`re saying the 1-2 change is haphazard but other changes are OK, could possibly be 1-2 solenoid. Easy enough to change. Ideally before even thinking of swapping out box you need to get the box codes read

The problem is a bit more complicated than a simple hang -- the error still comes up intermittently regardless of the hang between gear transitions and the hang very rarely occurs in overdrive (Sports Mode). It also has abnormally high fuel consumption, in the order of 20L/100KM or above. Fuel line and filter are fine, as is the exhaust.
An auto-box specialist suggested replacing it (this was a couple of years back and I forget the specificity of their reasoning, but it was sound at the time). They also sent it to someone who had the software necessary to communicate with the car which didn't turn up anything out of the ordinary.

I purchased the replacement box a while ago and just received it recently, so I already have it available for replacing.
