Re: LS engine swap info
You would need an electronic speedo, the truck will run and all without one, you will just be a target of Johnny Law without.
You can switch the tail housing out to a 700 ( or aftermarket) but I think that is expensive. You also can purchase an electronic speedo from many different guage companies, takes a bit to get them configured but it isnt all that bad.
The trans shifts the trans, the computer just monitors it and adjusts the rpm and or timing if needed, I really dont think it cares what the trans is doing.
