hey how do you put in the 1-2 accumulator piston? I bought an aluminum one and I need to drop the pan do to a leak anywho.

also what is the deal with the SK and the HD2....I know everyone here runs an HD2. But has anyone ever said why?

the h2 is more detailed and has better parts is what my trans parts store said,that is why that is the only one they carry

To answer the first question, it depends on whether or not you're following the ATSG instructions or the HD2 kit instructions. The ATSG's instructions direct you to point the legs toward the separater plate, whereas Transgo's directions direct you to install it in the opposite direction. I'd recommend going with Transgo's instructions.

As for the difference between the SK & the HD2... the SK is a shift "correction" kit (not a true performance enhancement). Ask me how I know first-hand. The HD2 is a full-on performance reprogramming kit. You'll see much better results & longevity with the HD2.

Hope this helps you out... by the way, there's a couple of 4L60E rebuild threads on this site. May wanna use the search engine to find 'em.

yeah I looked through the search engine, good info, I am doing a little research on it here and there, gonna do the shift kit later in the summer maybe. I mean I can't drive for 6 months....medical reasons....so there is no rush.

trans go flips the piston only to gain spring pressure because that side of the piston is thicker

i personally wouldent do it the trans go way just cause i liek to know that the spring is centered the gm way

i've torn aprart a few trans that have broke an acc spring from this piston flip
