Hi Guys I have a 2006 Sorento XS Manual (TOD). The transmission appears to slip repeatedly for a second when put under any stress like hill climbing. You get like a mild knock, a bit like something may be jumping a tooth when under stress. On the flat it pulls ok if you take it steady. Do these suffer at all with the drive chain going slack? Could that be the issue? Any ideas from you knowledgeable folks would be very much appreciated as I'm at a complete loss and don't know what to do.
