Has anyone ever used the "upgraded" 4L80E front band in a TH400? Stock the TH400 uses a 1" wide front band, the 4L80E uses a wider "high-energy" 1.25" band. From what little I can find online, it looks like the 4L80E band can be used, as long as a 4L80E Servo pin is used too. ACDELCO p/n 24223081. Has anybody done this and had any issues? I've seen it recommended in a few places, with mention of needing to measure clearance. What is this referring to?
