99 Cobra 88,000 miles. Lots of bolt ons including 550 miles on new Centerforce DF / Fidanza Fly / TOB / Pilot Bearing / U-joints. 10,000 miles on fluid change with Redline ATF. OTW immaculate maintenance record throughout. I've raced it twice, once with DRs, total of no more than 15 passes, over 1 year ago. Today on freeway I downshifted to 4th to pass a Jeep "infringing" on my space. No more than 75 mph at 1/2 throttle... BOOM went the sound (similar to falling out of gear)... Horrible vibration... Gear shift lever rocking left to right, so violent I could not hold onto it... ****ing fluid evident in white smoke out back... Shut car OFF (instinctive) and coasted to emergency lane. Im lowered a bit, and all I could see underneath was fluid dripping from trans front and back (btw I was parked on slight decline). Clutch pedal goes to floor, no resistance. Evident ATF red fluid and associated smell... this isnt a half shaft or an IRS issue. Towed it to a very reputable mustang shop in Ft Mill SC. At this point I understand everyone here can only speculate the damage, and I understand that. However, until they get under my car to explore I am doing my research to be ready for what can/does come next. Does this sound familiar to anyone else? Outcomes? I find it hard to swallow that my 305 hp baby just blew up the trans at 88k miles. PS If anyone wants to do me a kindness and post on Corral that would help as well, I have an acct there but never able to post and no mods will answer my kind PMs.
