Thanks gtpinsc for reading and the reply. I appreciate the tip on the vacume leak near the T boot connector under the SC snout. My mechanic, Evan suspected the plug wires and replaced them. He says that's all he did. I picked it (2000 GTP) up yesterday. So far so good. (No more shutter). If the shutter returns or the 2-3 shift misses even one more time, it's on., lol.
I'll check the T boot though, just in case,.
