Some of you already know the story, but I'll retype it for fun. I had a new 47RE built by a local shop that has treated me very well in the past. They got a single disk billet plate Axiom brand converter that has all the good stuff in it like 500RPM's below stock stall, furnaced brazed fins, billet stator, blah blah... I was just a little nervous about it being only a single disk. They did their own in house valve body mods with both a kit and also boring out a few ports. The truck was at stock power before and after the build....4 months later I pop in the new Edge Juice....now I can light that converter up like nothing on level 3-5. Full throttle is actually fine, it's part throttle to 3/4t that gets the converter shudder. Obviously, hydraulic line pressure is not adequit. This is when I met Jason at www.dieselnutmotorsports.com who filled me in on what Suncoast, and other big name trans companies do like ATS, does to their valve bodies to get the much needed extra oil flow and hydro pressure that a simple "shift kit" and mild porting just doesn't provide. I ordered a Suncoast valve body from Jason, trans shop replaced it for free, and it feels fairly different. The Suncoast valve body is actually smoother when shifting in drive and reverse, along with feeling a little smoother through the gear changes. The difference is lockup actually holds now, and darned well. All power levels on the Juice hold just fine at any throttle percentage. Now my Axiom converter holds just as we had expected when the trans was originally built. Definantly a well worth it upgrade, especially when combined with the much tighter aftermarket converter. Thanks for the help from dieselnutmotorsports, great customer service.
Congrats on the new toy, glad it fixed your problem. I really want to do a converter/kit in mine so I can play with more power, but alas, not in the budget right now. What power are you putting down through it now?
