This is a tko600 I purchased through forte as a swap kit. This has the adapter too mate too a t5 bell and put the shifter in the stock location. This trans is about six years old. It was rebuilt by Hanlon in pa after a shift rail broke about three months after installing. Tremec covered that under warranty and I added carbon fiber synchros and had bob do his shift rail work. Works great no shift issues grinding or anything. Going ls and auto is why is for sale. Have a umi torque arm and mount that goes with it. Pro 5.0 shifter Lakewood bell and spec stage three plus clutch and fly wheel. Clutch is about five years old and also working great. Located in md on eastern shore not so much on shipping but maybe if paid by buyer. 3250 obo
