Hey guys new to this site looks good. Have a question that hopefully can be answered. I own a couple of older trucks(1991 GMC Sierra and a 1990 454ss) in my 91 sierra I lost the tach then after I lost my speedo( I'm told needle gauges are rare in that year) I decided to rewire the dash with a cluster from a 93, I grabbed the cluster, external drac and wiring. It didn't seem hard to wire in the new cluster and drac but after I went for the first little road test my torq converter seems to lock up as soon as you start moving. In unlocks if you touch the brake. I haven't recalibrate the drac fully but would that cause the converter to lock up instantly while moving? Maybe I did something else wrong? Any help appreciated.
