It's because of my transmission woes. Its a long story but it involves a supercharger and my mistake of using RTV on the pan gasket twice, both times resulted in major breakage of hard parts. The last time it twisted the output shaft in 2 on a WOT 1-2 shift. I'm AWD so it hooks up. Never ever use RTV on a 4L60 pan gasket- the drain hole for the servos is right at the rail and if they can't drain they don't release. The RTV clogged that hole and they didn't catch it the first time. Both times Performabuilt covered the trans under warranty- and the last time it was a year after it expired. I just had to remove the trans, remove the tail and bell housings, and ship it across the country, then reassemble.
