As I have joined this forum very late so I would like to put some light on the Rexton problems, I am one of the Rexton owner, Actually the main interesting issue discussed above is gear box engagement in the morning, As there is a delay of 3 seconds or more so this means the clutch and brake bands inside gear box are worn out and a complete overhaul is required, they will change the whole maintenance kit then it will start working properly, and for Rexton I belive only El Naeel can do this job.
2005 and above model came with mercedes benz gear boxes so they do not show any problem but older gear boxes show this problem after 100,000 kms, I can say more how to use automatic transmission to have long life out of it.

Please share that your gear box problem is resolved or not?
