So... after an autocross event... that the LSD trans didn't make it home from (still a fun day).... A friend of mine had an open diff trans to keep me rolling until the appropriate LSD is found- was installed. On the way home from the shop I was on the highway doing about 65-70 when the speedo cut out as did the shift light. All seems to be intact at the trans. All connectors connected. Any ideas where else to start looking???

Also - if you have an LSD trans for an 88 NA. Let me know...
