well ... the problem is repairing the tranny is expensive and there is no garuntee that the valve body will function properly. my tranny is hard shifting when cold .. and mess up at the 3rd to 4th hanges untill it shifts with a hard shift ... then it vibrates at 100m/h if I stepped on the accelarator as it seems to slip and hold while driving ... 1st to 2nd it always hard shift ... so the tranny is f-up !! I dont really have that hope of fixing it. the idea why I wanted to use the 525 tranny is ... the Japanese specs tranny is shorter ratio as at 235Km/h the RPM is 6.25K, German specs is open to the 260Km/h with less RPM means less fuel consumption. the 525 tranny has the same 3rd and 4th ration ... thats the only reason. I couldnt find the German tranny in the scrap yard ... therefore I asked. I had an old friend who did the swap ... I liked the car, it was E32 735i ... but the OBC was a mess and the electricity too ... so I dont know what mess was in the OBC memory. if I was able to drop the tranny on the floor at home I would try the clutch repair but I will need a hydrolic jack up which I dont have.
how about transplanting a manual 5 speed tranny or 6 speed tranny? I heared that I will need a new drive shaft and clutch setup too ... I also need to disable the auto trans controller. ... any new tips? excuse my long reply
