Product Reviews700r4 700 4l60e Alto 3-4 Powerpack Kit High Energy 9 Plate HEG Friction Clutch

Great clutch set! Pushing big power and having no failures* (See full review) 10/10 would buy again!

Lets face it, 4L60E's are NOT the trans of choice. They're notoriously fragile. These clutches were originally purchased elsewhere and for more money and when mixed with a shift kit, the 2-3 shift was a bit too hard and we were afraid of breaking stuff so we backed off line pressure. BIG MISTAKE.. We ended up burning that trans up trying to get a shift that wasn't going to beat the gear train and truck up. We bought these clutches and redid the trans and LEFT THE SHIFT KIT STOCK.. Stock oil transfer plate (Actually ran a bit more conservative by peening the holes closed and redrilling with a slightly smaller hole than stock), added the accumulators and all the springs back in... This allowed us to run line pressures up further than stock, while maintaining a very nice shift.

Theory: Shiftkit makes the trans shift harder. If you want to cushion the shift a little, you have to back off line pressure, This makes the shift softer, but also reduces the clutches holding power, making for a weak trans and premature clutch failure.

Here's the counter intuitive part.
Stock, or modified mechanically to have a softer shift allows you to raise line pressures to get your firm shift back. This has a side benefit of allowing you to hold more power with the same clutches because the pressure applied to the clutches is much higher than stock.

Add Torque management within reasonable levels and you have a surefire winner.

After installing these clutches and a few other parts with the listed mods to the oil transfer plate and accumulators, the trans has been behind a boosted LQ9 (Cast iron LS2) making 650 wheel horsepower for over a year and has had 0 problems. Fluid is still as red as the day it was put in. Read full review...
