<< Very disappointing, I have hundreds of hours into the car and have spent almost $10K to restore and put the car back on the road. I'm good with engines, but drive train is another thing. Can anyone give me some guidance on how to trouble shoot this, or where to start? >> Lucky for you, this one should only cost you a few hours and about $6 from your local Radio Shack. The symptoms you describe are a classic trans governor failure, but you could hook up test lights to be sure. Take a look at the excellent articles written by Mark Hershey: http://www.dmcnews.com/Techsection/transputer2.htm http://www.dmcnews.com/Techsection/transputer3.htm There are a few more details (such as how to remove the governor) not listed, but this will give you a good start. By the way, be careful not to drape the wires to the governor across the exhaust pipes! [Inside joke] Jake Kamphoefner
