The Greatest Problem of the General Motors 8L90-E Transmission Has Been Resolved!
Known as one of the most unreliable mass-produced transmissions of all time, the 8L90-E is notorious for failing shortly out of warranty. Much of this can be blamed on one specific system, the “pulse dampeners.” Pulse dampeners are small pistons built into the valve body castings and circuits that are designed to modulate oil flow to the shift valves.
The issue is two-fold. One is that they don’t serve any meaningful purpose. Two is that they are the first component to fail in almost every 8L90-E we receive as a core. It is our belief that these pieces were designed specifically to limit the lifespan of this transmission.
Until now, the only solution for these problematic components has been machining them or sleeping them and replacing them with different pistons that will inevitably wear out again. For the first time ever, we have designed a kit that permanently eliminates this system from the valve body altogether as though it was never there.
This kit installs easily without dropping the transmission. Additionally, our billet channel plate is completely redesigned to bypass ALL pulse dampening circuits and dead circuits. As tested, oil travels through this channel plate 0.23x the factory channel plate, a radical difference.
This Kit Comes With:
- (1) Billet Channel Plate w/ PulseDelete™
- (7) Billet O-Ringed Pulse Dampener Plugs
- (7) High-Temp O-Rings
Conclusion:
This product was designed so that the 8L90-E transmission could survive hundreds of hundreds of thousands of miles safely. In all data we’ve collected, it was obvious that the pulse dampening system was the root cause of this poor longevity. Finally, a permanent and total solution exists. Still have questions?
