  1. Just had the same problem with 1999 c4 tip at 103k miles. At 85mph heard a Bam! dropped into 4th and seemed to start losing drive. D light and 4th gear light began alternate flashing. It seemed like I lost 1st, 2nd, 3rd and 5th but was able to drive to Uhaul location close by (was 300mi from home) and drove it onto an auto carrier. At my mechanic I found I had also lost R and N as could not reverse off trailer and N would not allow to roll off. Had to disconnect rear left wheel from axle and then it rolled. Still waiting for diag but expect the worst from reading above. I wish there was more info on what happened to the cases above but since years ago, I guess I will soon find out. If any additional info Please Help...
  2. 1999 C4 Coupe Tip-s... 103k Ran very well... Until last week on a road trip to Northern Wisconsin. On return to Chicago began to get a rattle in low end of 3rd, and 4th, then Bam!!! At abt 85 mph dropped to 4th and thats all I had. Lost 2,3, 5, R, N.. Luckily Uhaul was close and had an auto transport to tow it to my mechanic in Wayzata, MN. This is a daily driver, summer and winter. I am afraid it will be bad news $$$...
  3. Just as a follow-up... Finally found a used ABS Hydraulic unit at a salvage yard in Edgerton, WI. cost about $400. pretty easy install and had a local shop bleed and test the system. Checked out good and saved $$$. Would like to find a place to send the old unit for repair if possible.
  4. I have 1999 911 C4 (996) There is a leak in the ABS hydraulic unit part # 99635575540 Looking for replacement part but seems very specific. Any options on alternative part numbers? New part number 99635595560, Thanks,
