Something else is wrong. It should never be locking below 30 MPH (unless somebody programmed it to - which you certainly CAN DO.)....

Highway speed problems are usually misfire related.

I was having the same problems and it was misfires. When I did my heads & cam install, found a tip broken off on a spark-plug causing the problem.

Just wont lock up below 60 mph.

I have to throw the switch manually if I am cruising in fourth above 40 mph and the rpms drop by 1500
