TransGo Performance Transmission Service Kit - 4L6-CCV

New valve system corrects converter flow to the primary pump area so the converter will stay full under high load and RPM. This valve system does not require any pump machining, cross drilling or any modification to the pump or support. It does not require a solenoid but you can reinstall it if you wish. Always install a cooler for best results. Not Recommended for working trucks or towing. A non-lock-up converter increases transmission temperature which can lead to overheating in these vehicles.
