A typical transmission fluid change replaces only around 40% of the old contaminated fluid.
The remaining fluid is trapped inside valve bodies, the torque converter and transmission cooler
lines. New fluid can often loosen damaging sludge and varnish deposits,
but not remove them, which can lead to shift problems and even transmission failure.
Our WynnsTransmission Service removes 95% of the old contaminated fluid utilizing a specially formulated
transmission cleaning chemistry that safely removes harmful sludge and varnish deposits.
