Excess heat

Cause:

In early-design ('11-'16) valve bodies, the thermal element can often become stuck in the bypass position, resulting in an overheated transmission.

Correction:

Replace the thermal element lineup with this bypass plug and clip to eliminate hang-up issues.

Warning:

It is recommended that this kit only be utilized in warm climates, or with synthetic fluids when used to replace the OE thermal bypass element. If used in '17-later applications to replace a missing blocker plug, it must be used in conjunction with Sonnax converter limit valve kit 126740-25K. See instructions for details.
