It all depends on what size motor that you chose. I believe that the Silverado feels and handles better than a Ram at high speeds.
Most likey its the TH400. If it has 4 speeds, its the 700R4 (w/overdrive)

they have preset speeds, they are not changed

Land tortoises travel slowly but can sometimes manage human walking speeds

Its not the relay, it is the blower motor resistor.
Changed transportation speeds from under 10 mph to over 60.
A catalyst.
The rack and pinion steering unit needs to be replaced
