Looks like my luck has run out with the 4l60-e. On my way to my girlfriends house this morning, I was having all sorts of problems. Clunking, didn't want to downshift, slipping...

I guess Ill drop her off at the transmission shop tomorrow and hope for the best.

Hope it's just low on fluid and didn't have enough fluid pressure... good luck.

I upgraded my E-fan relays to 80 amp relays and sockets. That harness is a real PIA to rework. Then I washed, clay barred, and waxed with Tri Nova's Liquid Carnuba Wax. And while I was doing that, USPS showed up with my new AC belt tensioner so why not.

Yeah I know. It looked like option 3 was to buy new downstream sensors and turn them back on. I would try them behind the new cats and see if it's a problem first. I've seen it go both ways and would try the ez option first.

That was my thought except I was also thinking that if I want to add a bung I'd better have it welded in before the headers are installed or forget it.
