So I got up the nerve to replace my solenoids on my 07 impala ss. I got Dave's kit from TEP and put new solenoids sonnax boost valve and trans go shift kit in. It drove perfect at first. So yesterday I went to go take it on a drive was fine until I got about a mile out the driveway and it started revving with little pull. I noticed 1 and 2 pulled perfect with snappy shifts. 3 was kinda lackluster and drive was almost non existent. Any ideas on where to start?
