TRNW-2: UI51E valve body question

We usually use the Transgo kit and replace the SLT and SLU (lockup and 
EPC) with OEM. Although replacing all of the linear solenoids isn't a 
bad idea. The OEM solenoids are getting pricey though so a reman valve 
body isn't a bad option. I haven't had good luck with aftermarket solenoids.
