He picked up his 96 cobra with 50k miles a few weeks ago and noticed some tranny problems. It seems to always grind going into 5th gear, sometimes after it's been driven awhile it won't do it. We changed the tranny fluid to Royal Purple synchromax and adjusted the shifter stops, but that didn't help. I'm not sure what it is but I'm guessing it's the synchros. Also, when it's shut off and you put it in 5th gear, the car will still roll. Anyone have any suggestions on what could be wrong??
