I"m trying to get my tranny back together...and Am having a weeble-wooble of a time trying to get the end case (shifter housing) back on...The 5/6 gear lever isn't going into it's groove hole exactly..is there a trick to getting this thing to hook in right...or did I not allign the 5/6 lever in right...I did have to shimmy it a bit to get the gear selector guide pin to line up...and when I put the Reverse lever guide pin in the 5/6 gear lever became really stiff... does this sound right...
