MalMac 1,331 #1 Posted January 4, 2017 Is there any outwardly appearances to a HC transmission identifying it as a HC transmission VS a regular 520H transmission? 1 Share this post Link to post Share on other sites
c-series don 8,872 #2 Posted January 4, 2017 Hmmm, now that is a good question. I don't know the answer to that but I will definitely be checking back to see if someone knows! Share this post Link to post Share on other sites
JackC 617 #3 Posted January 4, 2017 I do not know for sure but i do not believe that there is. There may be different part number on the transaxle somewhere. Share this post Link to post Share on other sites
lynnmor 7,356 #4 Posted January 4, 2017 (edited) See the "Faster hydrostatic rear ends" thread. I don't know if it will answer your question. I do see that the HC has two pipe plugs, an extra one in the side. Edited January 4, 2017 by lynnmor Share this post Link to post Share on other sites
