Got cover on with new gaskets on shift lever housing--levers(hi/low and pto) shift easy and 240/1000 selector turns easy 1/4 turn....no pto and no lift at all in 540 position--in 1000 position have lift with pto turning but no lift any other position....will not shift into 2nd and 3rd gear.Does any of this craziness make any sense ---I am now desperate--I have done all on earth I know to do....what is the secret? Please help ..... Thanks
