Message: [QUOTE="Chris, post: 654032, member: 400"] the truck will be faster with the 4r. it will also be more reliable. Some people have great luck with a built 5r, some dont. Weve been installing brians built 5r's since 06. He has experience with them. The problem is the clutch synchronization. It HAS to be perfect or youll tear up direct clutches over time. A 4r is much simpler in its function. If brian is recommending a 4r to you, Id take his advice. Hes got the best service in the industry, bar none. This is why we only deal w/ him. You have to drive a 6.0 or 6.4 w/ a 4r in it to really appreciate what it adds. Everyone thinks that be giving up a gear youd be going backwards, but theres more to it than meets the eye. The trucks spool faster, accelerate quicker, and smoke less. We have gotten the swap down 90%. We have no check engine lights, no wrench on the dash, no weird starting or stopping issues. All we have left to do is gear the lights to illuminate correctly on the gear shifter and work out the cruise control. For a 500hp pure daily driver, The 5r is the way to go. If you are pushing 600hp or north, the 4r is the best option as far as performance and reliability goes. [/QUOTE]
