Been searching for a replacement TCM for over 2 months & was told at every turn they were back ordered for up to 2 years. Found a couple places that said they could repair & reprogram, but little or no warranty. Finally found GoECM in Houston and Grand Prairie, TX
www.goecm.com. They can repair/reprogram just about any TCM unit and was able to secure one. Options are to send yours in & have it rebuilt for about $1600 with 1 year warranty or buy a rebuilt for $2995 with Lifetime warranty. No brainer there. Ordered one & about 10 minute job to replace. Send old one back for $100 core charge & problem solved for good !! On to the next problem that arises & hopefully as easily solved. Seems this is a problem with most of these same units.
