Are you saying that Tremec is sidestepping their warranty obligation because Keisler opened up the box to make their modifications?
Does Tremec recognize Keisler as an authorised distributor of their product?
Did Keisler know you were going to race the car before they did their mods?
If they did the work try to find out why they won't stand behind it. Ask Tremec why they won't stand behind the components in ther transmissions and tell both of them their answers will be made known to their customer base.
You got stuck on a technicality, too bad neither one of them will step and take care of a customer, not surprising however...more like typical.
Start harassing the top dogs and don't let up. Let us know what happens.
