A while ago I priced a TKO 600 Tremec at $2400 starting price but with special bell, clutch, TO, shifter relocate, driveshaft, etc etc it rang up to about $4400. Then I had to cut the floor and butcher cross member which costs are not included above. I doubt if the price will ever go that low from my conversations of past with Jaimie. He indicated it would go from $4200 upwards. If you have the 18 spline clutch at present it is simply a 2 hour job to change this no other parts required. That is a great offering at the price.
