A
common problem with automatic transmissions is rough and hard shifting
due to poor maintenance. Nearly nine out of ten transmission failures
are due to overheating and fluid contamination, according to the
Automatic Transmission Rebuilders Association. Automatic transmission
fluid suffers from heat, friction and contamination. As time goes
on, the transmission's vital parts begin to coat with sludge and
varnish. According to ATF (Automatic Transmission Fluid) manufacturers,
the addition of new fluid to contaminated fluid can actually cause
sludge and varnish deposits to clog filters and restrict the flow
of transmission fluid.
A
regular transmission drain and fill service can leave as
much as 75% of the old ATF behind in the torque converter
and transmission cooler. When new ATF is added, it is immediately
contaminated by the old ATF left in the system. The deposits
left in the system can seriously impact the proper operation
of the transmission.
The
Transmission Flush service is performed using a MotorVac
machine. Either machine is powered by the vehicle's battery
and is connected to the transmission cooler line using the
supplied adapters. The Transmission Flush is added to the
transmission with the engine idling. The flush safely dissolves
harmful deposits and suspends them for easy removal with either
machine. A Transmission System Flush Service will replace
up to 95% of the old ATF with fresh ATF.
