I was browsing through Canuck Barrys new web site and he has a couple of paragraphs on how to shift the 2 speed trans. It says low gear can actually be taken to 100 MPH+ , but must be brought back down to about 60 MPH to shift to high or overdrive . We all know that you shouldn't power shift from 1 st to 2nd , but I've never heard that you need to slow down to about 60 before shifting to 2nd or overdrive. Has anyone else ever heard this ? I've taken mine up to 100 + dozens of times , backed off the throttle and shifted but if this is harming the trans ., I'd like to know .
