Transgo shift kit and pistons too?

[2005Lesabre]

I did pretty much what everyone has mentioned (TransGo 1-2 & 2-3 accumulator springs & spacers, the 2 TSB magnets, & Sonnax Lube Tube retainer). I did however, also replace the piston seals (O Rings) and the accumulator cover gasket. We'll see how this plays with the occasional P1811 I've been getting when the trans is very hot.

When I installed the TransGo kit I felt the difference before I got to the end of my block!!!

Keeping the trans under 200° helps a lot. In addition to running Dexron 6 fluid should help prolong the life of the trans
