boogamanXR6T Member 30 Member For: 17y 8m 18d Location: Brighton SA Posted 07/11/06 12:14 AM Share Posted 07/11/06 12:14 AM apologies for the long post but I need help - in many ways...I recently ran a Capa edit through my BA XRT 4spd auto and a couple of days later she started to slip changes into 2nd under full power - then it started to jump around looking for gears - then it started to slip into 2nd under 3/4 throttle - then it started slipping the very first change of the morning into 2nd at 1500-2000rpm.I put it back into factory tune and it wouldn't miss a single beat no matter how hard I tried - although I did get the faintest 'whoop' sound when kicking back to 2nd from 65kmphgot the Capa box reloaded with updated software codes and that took away the jumping around for gearsthe current status is:-now it drives fine in perf tune at mid throttle-3/4 throttle or more will make it slip into 2nd-SSS with the shift firmed up under full throttle is a silky smooth shift - not firm - but no slip at all-first change of the morning into second at 1500-2000rpm is a slipper-at low throttle the firm shift SSS is actually firmBACK INTO FACTORY TUNE AND IT DOESN'T MISS A BEAT AGAIN!!! this is driving me insane.I can't get ford to fix it under warranty if it doesn't do anyhting wrong in factory tune - but they've been trying to get rid of the faint 'whoop' sound for me - so far new torque converter but no change to anythingcurrent talk is solenoid - so we're going to turn up trans line pressure by 10% for both auto and firm SSS and see what happens - the theory is that if it changes fine in auto and firm shift actually becomes firm then the solenoid is at fault - if it still slips into 2nd under power then the bands are gone on 2ndanybody got any suggestions? all help appreciated Link to comment Share on other sites More sharing options...

I know there are not many places to try it but if it slips 3rd to 4th as well but 2nd to 3rd is ok I would bet London to a brick it's the bands.
