Jegs 4L60E Torque Converter Conversion Kit provides a solution for vehicles experiencing slippage and heat buildup due to a non-locking converter. It optimizes converter flow to the primary pump area, ensuring it stays full under high load and RPM. The kit includes a new valve system that eliminates the need for pump machining or modifications, and it's compatible with non-lockup converters only. Installation requires computer reflashing to disable the lock-up function and ensure proper operation. Always use a cooler for best results.

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!
