sunstrand hydro gear or piston to piston

[mrc 841]

hello men, i just finished tearing down an old C160 auto.

                  the tag on the tranny was covered in grease and crud. the tag reads 90-1140. 

                  is this a hydrogear or piston to piston? 

                  can you tell from just a visual? 

                  if so , how?

                  thank you   mike in mass.

If the hydro motor looks like a figure 8 it is hydrogear.  Round is piston to piston.  If tow valve is on the top hydro gear.

thank you pfrederi and the tuul crib for the quick reply.    i was under the impression that the hydrogear tranny was basically a remove and replace kind of thing.  tuul crib from the pics you have a hydrogear correct?  you seem to be doing a great job bringing yours back to life.  i always hear about lapping the swash plates and slippers. so a hydrogear can be repaired?  thank you mike in mass.
