The kit firmed up the shifts, and improved drivability.
It also claims to increase the life of your transmission, by creating higher line pressure, and reduce clutch slippage. I installed it my self, if you would like to know how hard it was or what’s involved let me know.
If you would like to know the part number of the kit, I can tell you.
Better yet here is the website that sells them.
The link below is the kit I have:
