My '00 2500 Automatic has started to shudder while towing 26' Travel Trailer up moderate grade inclines. I am told TC is probably culprit. Currently upgaded with BD PNP, 40 Horse Injectors, BD Exhaust and modified Valve Body, and totally synthetic. Have been given choice of BD or Banks TC. Hope I'm not opening up something here; just looking for a little comparison feed back on pro's and con's before I place my order and put my hard earned $$ on the table (to never get it back again). Am leaning towards installing X-Monitor for Pyro, Boost and Trans Temp at same time. Anything I need to know about its performance (also fairly$$). I understand there are now good ways to hook-up Fuel pressure gauges also. Any guidance as to where to start looking for these? Thanks in advance!
