Hello to all I have a 2003 s-type 3ltr V6 with what appears to be a gearbox nightmare it judders at the rear ns at low revs fluctuations on the Rev counter as well clunking sometimes from first to second the gearbox was updated last year but the problem seems to be getting worse so far I'm very been told it could be the torque converter the coil pack or the gearbox oil which needs changing but I'm lost to know which one it could be if anyone else has had this problem please tell me how you solved it and a rough estimate on the cost thankyou in advance stu
