Royal Purple Syncromax
OK I have a 00 vert 6 sp with 74,000 miles and just bought 4 qts of the Royal Purple Syncromax. I have read all the post on the forum about the "problems" that people feel are associated with this fluid due to the paper blocker seals. My question - Has anyone with a 00, 99, 98, or 97 6 sp trans who has used the Royal Purple Syncromax in their trans experienced any leaks or trans failure after the change?
In theory I understand what has been said, but I would like to know first hand real world if anyone has had problems.
Thanks is advance for any responses.

I did a search on the forum (royal purple) and found several responses where members had said that roypal purple sycromax was a problem with 2000 and eairler manual trans due to the paper blocker seals and that problem went away as in 2001 GM went to carbon blocker seals. Bur I have not seen any post where a member had a leak or failure due to this problem.
