Got this http://www.suncoastconverters.com/do..._products.html new kit install & just tested the truck. The shifts seem to be chrisper than b-4. The only bad part will be when/ if this solenoid goes bad. They tell me that you have to purchase the kit. Can't get just solenoid. I don't know why I wouldn't be able to replace just the solenoid. It just bolts in...I was able to get all the #'s off the new solenoid so, if it happens to go bad. I may luck up & find just the solenoid. Well, I tried to just post the pic. But, was unable it's under kits & components. It's the governor pressure upgrade kit

Maybe someone can post just the pic
