Hi all. Im new to the group and hope everyone is well. I have recently acquired a Grand Voyager 2.8crd with known gearbox fault. I have purchased the replacement box and am going to change it next week. Is there anyone here that has done the job and could offer any hints and tips. I am a very able DIYer and have done major mechanical work on other cars. Any do's or dont's would be greatly appreciated. Thanks in advance
