:E39 528 not going into 5th gear
I had my gearbox done because it was slipping and now that i have it back it doesnt go into 5th gear, the gearbox place replaced 5 valve boddies in the box and he recons the gearbox is mechanically sound. When in 3rd gear you must go just over 60km/h and release the accelerator cable a bit before it changes to 4th but doesnt go into 5th at all. The ASC light has also been on since i have it back? Ive read threads that it may be wheel sensors that are faulty? I had it by the agents and the fault code 100 speed monitoring comes up. They also say that gearbox is faulty. The gearbox place says they will put another box in but if it does the same they will charge me labour costs for it which i really dont want as i have spent too much money already on this problem. When it came back from the dealers only the speedometer was working and none of the other gauges, dont know if all this is connected in any way? Could someone please give me any advice as to get the box changed or have sensors etc checked?
