I just got a 95 Diablo VT. I'm getting a beeping sound when I go into 5th gear a lot. After a while the the on/off beeping sound (like when you first start your car with the seat belt off) goes on full time (one straight sound). When that happens, the transmission feels like it goes into a lower gear and a loss of power. As soon as that sound stops, the transmission comes back to normal (feels like it has gone back into the gear it's supposed to be in) and I get the power back.
I'm having it looked at later this week, but just wondering if anybody knows what might be going on.
