The wisdom of site searches
If you search the board for previous posts about member's experiences with TQs you will find a lot of exchanges about different brands. This is coming from actual users and having done that myself I can tell you PTS is highly recommended, lot of satisfied customers.
But search and read for yourself, that's what the archives of previous posts are for--don't take Bruce's word or mine, listen to the "group."
I had a TCI trannie and convertor, the trannie did not shift well when it was hot and I traded the TQ for a rebuilt D-5.
