I doubt it. Most places don't even like to touch automatic trannies. I took mine apart and I see why. If you can find a hardcore race shop that's used to working on domestics with auto trannies, that's probably your best bet. Those places are used to rebuilding automatics and installing shift kits in the valve body. I had mine built for racing at just a tad bit over the cost of a normal garage rebuild. Small import shops that specialize in installing cold air intakes and selling seatbelt pads is not where you want to take your car for this problem.

By the way, I've had all the symptoms you've described and worse. Trust me, get it taken care of as soon as possible. It really sucked when my first tranny in the Z blew...2 hours away from home!
