Jegs 4L60E User manual

  • Hello! I've reviewed the user manual for the JEGS Torque Converter Conversion Kit designed for 4L60E, 4L65E, and 4L70E transmissions. This kit is built to address issues with slippage and heat when using non-lockup converters, and requires computer reflashing for use. I'm ready to answer any questions you have about its installation or usage.
  • What type of converters this kit is for?
    Do I need to reflash computer after installation of this kit?
    Is this kit recommended for working trucks or towing?

This kit is designed to address:
Slippage and heat build-up from the converter
not staying fully charged under load once the
lock-up clutch function has been eliminated.
1. With a small at punch and hammer, remove
the orice capsule by hitting the high spot on
the capsule shown on the diagram below.
This will expand the capsule and allow you to
remove it with needle nose pliers.
The new valve system corrects converter ow
to the primary pump area so the converter
will stay full under high load and RPM. This
new valve system does not require any pump
machining, cross drilling or any modication
to the pump or support. It does not require a
solenoid but you can re-install it if you wish.
Always install a cooler for best results.
Not Recommended for working trucks,
vans, suburbans, or towing. A non-lock-up
converter increases transmission temperature
which can lead to overheating.
Do not use O-Ring on
end of input shaft!
