I had mine replaced with an ACE Converter http://aceconverter.com/. The price was right. $424.50 plus shipping. He had a core so he got the rebuilt to me quickly and I was able to send him the core after the install. It arrived on a Wednesday. Tozo installed it that weekend. I sent the core back on Monday. Easy process.
I'm happy with it. Torque Converter with shipping both ways + New Transmission fluid and filter + 4 O2 sensors + Labor was approx $2630.
I've been driving it for about 6 weeks since the TC swap. I check periodically for dreaded P0741 code - no issue. I got the Eurocharge tune at the same time I replaced the TC. The car seems silly fast to me. Shifts great. I'd do it again.
