Had my zf RBT 5DS 2/201 in my SPF GT 40 P2116 - just had trans overhauled - and when i got it i could shift it manually thru all the gears-- when i started it up it was in reverse. I can shift it into all the other gears but it will not come out of reverse. Only thing i did was a lot of manual shifting of linkage to get it all adjusted properly. Any idea what the hell i did to it. When i got the box it was in neutral. Already had to pull it out once because we put the ring gear on the wrong side--on side for a Pantera --argg.
