Default rebuild mp7 transmission, Saturn TAAT transmission, Locks up in reverse, help

I rebuild my transmission in my 1999 sl2, Vehicle shift well in all forward gears, but when I shift it into reverse, it appears to want to go forward, and locks up. I read in another form that someone had the same problem, and found that they installed a part backwards. I removed the transmission again, and went through it, and I can't see where I made a mistake. Any advise?

REWARD EXCELLENCE!

If it is going forward in reverse ,then there must be some problem with the
forward /reverse servo ,or the related gears that the shift fork engages
otherwise there is not enough pressure ,to move the servo piston enough
or some binding in this area ,!
Can you push the shift fork into the reverse position ?
does it snap back to forward range ,when released ?

...
Have A Great Day , it is YOUR choice !

From the service manual.


Complaint
Transaxle Binds in Reverse and Creeps Forward in Neutral
Clutch Clearance too tight.

Possible cause
Clutch plate tangs not aligned to gear hub.
Check clutch clearance and repair as required.

Correction
Inspect all gear/hub assemblies for proper engagement into clutch plates.

Complaint
Transaxle Binds Up in Reverse

Possible cause
Damaged or rolled input hub seal rings.

Correction
Remove end cover and inspect input hub seal rings.

You purchase the latest version of the TAAT manual, http://www.ebay.com/itm/TAAT-Transmi...lVQncx&vxp=mtr

You can use the TAAT section of any 93-02 FSM which usually sells for 20.00. The used car manual places have these.
