SM420: Who has one and how do you like it? What's it in the middle of?
Good trans - short and lowest of the granny gears but harder to find than the newer truck 4 speeds. Notice the SM420 hoarders that have replied already? Depending on the specific details of your vehicle (ie wheelbase, engine, t-case etc), a SM465, NP435, or T18 might be easier/cheaper routes to a similar end - a deep 1st gear, great strength, short overall length compared to a NV4500.SM420: Who has one and how do you like it?
