Because Pacific Driveline is a dedicated transmission and differential repair and rebuild facility we simply don't have the time or space to provide periodic maintenance as well. But we would like to help you in advance by pointing out what you should do to ensure you get the most life out of your driveline before you visit us.

Your transmission's vital parts get clogged with sludge and varnish deposits because, just like the oil in your car's engine, automatic transmission fluid (ATF) suffers from heat, friction and electrochemical degradation. In fact, nearly nine out of ten transmission failures are due to overheating and fluid contamination.**

However, unlike oil, which can be completely drained from your car's engine, most of the transmission fluid cannot be drained. Instead it stays in the torque converter, valve body and transmission cooler lines, making a complete fluid drain impossible.

Typical transmission service removes and replaces only 25% of your car's contaminated automatic transmission fluid. Adding new fluid to the remaining contaminated fluid can actually cause sludge and varnish deposits to clog filters and further restrict flow. This can result in a serious malfunction or even complete failure of your automatic transmission.
