I still have the original 2004r (140,000) in the car now and now under WOT the trans will stick at about 4k rpm in first gear for about a second and then procede to go to 5k and then shift normally.. Still very drivable under normal driving. Anybody have a diagnosis for this? Already planning on...
I had the same problem, try loosening the bolts on the DP and rotating/shifting it slightly to give a little more clearance. It worked for me but I just run an open DP so it rotated with no problem...
