I just picked up my zf5 from the tranny guy on Friday.

He does a ton of zf5’s and zf6’s, he even keeps the syncro rings I’m stock. Free inspection and a 1 year, unlimited mile warranty. He found me a new case because mine had cracked, and did a reseal and new synchros for $700. It would’ve been $400 if I didn’t get the case. Right next to Cordova truck off of happy lane in rancho Cordova. It backs up to
Mather airfield. He does it right, I will always bring him my stuff.
