He got back to me...
"Had nothing but trouble shifting that Bitch Poo...
3rd set of synchro's and I was done..
"
I'm asking if he knows any other options besides the V160 since he's been building crazy cars since before I was born.
EDIT: His reply
"The newer TKO/Tremec line got much better Synchros "
I'm taking that to assume Tremec knew they had an issue and have fixed it... Honestly I'd be contacting Tremec directly.
