trans troubles can somebody id.

While trying to figure out why my tranny slips inbetween gears I decided to check the transmission code. Well its not a BRF, its a KTF what would this tranny have come in? I have a spare QTF tranny which one is better or does it matter. By the way this is in a 86 t-type.

Looks like the KCF is for a large car with a 307 Olds V8 engine. Don't know about the QTF. Here is a listing of many of the codes: http://members.aol.com/powerrslid/thm2004r.html
