When I start the cruiser and put it in reverse it engages fine. Drive to the local trails and shifting is fine. It's not perfect but it engages in L,1,2,and 3 with out to much effort. Once I hit the trail and put it in 4high and lock the hubs it is really hard to get in any gear and I have to really force it to engage. any ideas? Tranny is a sm465 hooked to a v8 and a stock 3speed transfer case.
