Anyone know about the 4L60E 1-2 accumulator?

What about performance gains? Has anyone quantified the difference before and after the upgrade?

I saw around a 15% improvement in shift times with my new accumulator. It’s definitely noticeable on the road!

That’s impressive, scottwilson! Have you noticed any downsides to the upgrade, like harsher shifts?

Not at all, jeffreyreed. The shifts are actually smoother than stock! You just have to ensure you don’t overdo it with the pressures.

That’s good to hear! Has anybody tried combining it with a shift kit? Does it make a significant difference?

Absolutely, garybuchanan. A shift kit combined with a better accumulator works wonders. Just be cautious about how aggressive you get with the settings.

I’m excited to upgrade mine now! Does anyone have humorous stories from their installation?

I once dropped a bolt in the transmission pan. My neighbor still teases me about my ‘new metal flavor’ in the oil!
