Hi All, I just had my selespeed actuator replaced cos the housing broke. After replacing a recon actuator, the car is able to engage into 1st gear and reverse gear only. Cannot engage 2nd, 3rd, 4th etc. But without engine being started, it shows can engage all gears. What could be the likely reason. Any help appreciated. Thanks. By the way, car is still in the workshop trying to resolve the problem
