My 1955 V8 Studebaker President, two questions. One a proper highway speed. Two, someone said Dextron or Ford for the Automatic, how do I know which to use? They don't mix,do they[?]

What do you mean by "proper highway speed?" The correct answer is the legal speed limit <G>. With that said, you bring back memories of when my boss, at that time, purchased a new 1955 President. I was in that car many times in excess of 100 mph. A 259 V8, automatic transmission (DG250 with lock up torque converter) and a normal rear axle ratio will cruise along with any modern traffic.

I don't believe in mixing different fluids. I don't know why you would want to. Drain your transmission AND torque converter and fill to the proper level with new Dextron. Whenever I have had cars with DG250s, I followed this procedure every year. I believe that it is cheap insurance for these transmissions. This is just one man's opinion - based on experience.

I drove it President home today. Man does it run/drive wonderful. I drove 65mph indicated on the spedo. The odometer seems to be exact. This has 205/75R 15 tires.[8D]:)
