Redline MTL or GM Sychromesh?

I am buying a 3550 with 10K miles on it and it has Redline MTL in it but a few people have told me to replace the MTL with sychromesh because the MTL will eat away at the synchros faster then GM Synchromesh will.

Any truth to this? Maybe I should ask Bob Hanlon?

I bought my 3550 from Mike Forte, he says don't use anything but GM Synchromesh in it.

Tremec suggests using GM Suynchromesh in the 3550 and TKO as well as some other transmissions. The Red Line is OK to use once the Transmission is broken in.

I once was concerned about this. I called Tremec up and asked them what was best to run. They recommended Syncromesh OR ATF.

So I put Mobil 1 ATF in the tranny and never looked back.. The tranny now has about 30k
