Hello. I have a 97 burb with the 350 and 60e. It doesn't shift into 3rd gear. So the 3-4 clutch pack is done. In looking for a rebuild kit. I found a tci master kit that includes all clutches and steels, gaskets, and band for 180. Or the same kit with the vett servo and a shift kit for 275. Is it worth the extra to get the shift kit on a stock burb. Its a dd family hauler. Thanks
