I was going through some TM’s noticed the top speed of an M38A1 is 60mph. I can only get up to 35mph cruising in mine. It seems slow compared to what I’ve read online. 1st gear shifts usually at 10mph and 2nd at 20mph. 3rd comfortably cruises around 35mph before pushing it. What would cause this? Did someone change the rear differential gearing?
