Title: Ar25 box
Post by: Larsen on 19 December 2013, 08:17:44
Hi Omega owners. I have Just fitted a Ar25 Box in my 96 model from a 98 with 228000 km on it. But I cant get it to move i First gear and im sure it did before i took it out of The other car.
I have tryed change Oil, cleaned filter, Adjusted and clean The shifter. Have Even changed Every Bit og The wire in The Car.
Please Any idé.

Are the lights working? Showing which gear selection is active?

Worth bearing in mind the AR25 is a bit weak for 2.5TD, if you can, better off fitting stronger AR35 from  3.0/3.2. That will allow you to chip the engine back to BMW Spec bhp  :y

Before i cleaned The shifter it was popping out of gear in d but other gears was fine. Now it all works like a charm. But still no First gear.
I bought a whole Car and mowed engine and Box as a unit to my own car. When The rear is lifted The Wheels Are spinning but no torque as I Can Hold Them with just a foot

That reads like you did an ENGINE oil change .. have you checked the GEARBOX oil level with the engine running.....

Couldnt find a correct tcm atm. But have been testing The gears. And seems like its both First and second gear that wont work proberly. First is behaving as nothing changes from neutral. In Seckond u Can feel it wants to drive but just cant.
Its There Any way to fix this other than fitting another box.
The Oil was as dark as coffe before change. But wasnt Smelling like a realy worn gear Oil Can do but ofc smelling used.
How many times is normal to change Oil Before its good?
I have one time had it in seckond and suddently it tryed to attach cluth but failed ( wasnt going into limp mode)
Hope somone Can give me some advise. And is there Any who have tryed change clutch on these boxes?

Mery Christmas to ya all. :)
