doesn't matter, it they didn't upgrade some hard parts, spend the 65 bucks get the book, it'll show you what needs to be chaned as your power level goes up..
this is what CKP does to make it live behind up to 500hp/500ft lb torque
The 2004R STREET/STRIP TRANSMISSION is reccomended for most high performance street and strip cars producing up to 500 horsepower/500lbs. ft. and weighing up to 3500 lbs.Perfect for low 11 second TURBO BUICKS,as well as all small and big block Buick,Cadillac,Chevrolet,Oldsmobile and Pontiac vehicles.All of our 2004R transmissions are in car tested and calibrated prior to shipment.The main mechanical failure in the 2004R trans is the forward drum.Our units come with this item STANDARD,not as an option.Although we have had cars go deep into the 10 second zone with this trans the durability of the overdrive section becomes questionable.When these parts break the vehicle will not go forward or reverse.For applications over 500 horsepower/500lbs. ft. and 9 and 10 second et. capable cars look into the 2004R PRO STREET/STRIP TRANSMISSION packages.Look over the build sheets and compare our builds to others based on components,not the "STAGE" designation.You will not find a similar trans at a lower price anywhere.

Over time the factory metal thrust washers wear and as a result increase operating clearances and send debris through the transmission.All metal thrust washers in the transmission are replaced with high capacity low drag needle bearing assemblies.This is a time consuming process but definately beneficial for a performance transmission build.Internal components are machined in a lathe to create pockets for the bearings to locate in,as well as generate proper clearances.These bearings also reduce internal friction.This results in lower thrust surface operating temperature,and reduced horsepower loss.

RECALIBRATED VALVE BODY AND GOVERNOR
Valve body is completely disassembled ,all parts are cleaned and polished,mating surface is decked and all circuits are then pressure checked to verify proper function.
Over 20 years of research and development have resulted in the ultimate combination of performance and component durability.The main problem with this transmission at high power levels is the direct clutch.Our custom seperator plate removes flow restrictions that cause 2/3 upshift delay and friction element slip.Our revolutionary "3/2 Control Valve Delete" removes the infinitely variable orificing of 3rd accumulator oil to the servo release from the hydraulic system,and uses a single orifice.This is the real correction for direct clutch failure.Custom automatic shift valve body and governor combinations can give you the wide open throttle upshifts your vehicle needs.Calibrations can be made to allow wide open throttle shift points anywhere between 5000 and 6500 rpm's,without shift timing complaints at light or part throttle
