Jason,Ihavent built many 4l80e transmissions for the Buick community at this point.There is a customer from Philadelphia that had his installed by Bill Moss Automotive in Philadelphia.You are welcome to google them and ask for Bill.About 8 years ago we started getting interested in the 4l80E transmission .This evolved into 2 manual valve body with transbrake types.Type 1 was My ORIGINAL DESIGN,which utilized the pressure manifold to control the shift schedule by allowing it to control solenoid operation with a 12 volt power supply to the trans and a toggled ground for transbrake operation and lockup.Type 2 was a version of TRANSGO HD kit with a B solenoid used to apply transbrake in manual low.Like anything its in infancy the Transgo kit had its drawbacks,and my original design required a custom seperator plate and a killer internal 12 volt solenoid that was discontinued by PARKER Hydraulics.Occosionally when solenoids werent available we would use the Transgo kit and had mixed results.Over the last year and a half we perfected the original pressure manifold type.HERE IS WHERE THE TROUBLE STARTED.As soon as other entities realized how easy it was to duplicate the manual shift valve body by our use of the factory pressure manifold we were copied.This resulted in another redesign as we were frustrated by our design being stolen after mentioning how it worked to others or by others who purchased it and copied.What we have now,is by far ,the best forward pattern full manual transbrake valve body for the GM4L80E,GUARANTEED.Completely redesigned and tested.150 real man hours resulted in another truly remarkable milestone for the 4l80e transmission.If you are contemplating a 4l80E for your car feel free to call in and discuss it.I will guarantee to not only beat anyones price ,but supply you with a top quality product and back it up with a 1 year warrantee.Lets use this post to track your purchase and results with the original perforamnce 4L80E builder,CKPERFORMANCE.
