Automatic transmissions are reliable, shift smoothly, and can last without issue so long as they are properly maintained. Over time, the transmission fluid becomes thick and the filter becomes contaminated with small metal particles. This can cause excess wear, high transmission operating temperatures, and eventual failure. To prevent this we recommend changing your filter, fluid, and seals to ensure your transmission continues to operate flawlessly. We recommend filter and fluid changes every 50,000 miles. Included in this kit are high quality Red Line D4 ATF fluid and OEM filters, seals, and plugs.

Turner's Tip for a healthy S14:
+ Take a peek at your alternator � is the alternator belt riding a little crooked? If it is � replace your alternator bushings with our HD ones (and replace the belt too)
+ I suggest keeping a spare cap and rotor in your tool box. They're hard to get in a pinch and I have seen them go bad out of the blue.
+ A spare fuel pump relay is a good thing to have too.
+ Keep an eye under the water pump for any signs of weeping � usually they give a unnoticed warning when they start to go�
+ For best performance replace spark plugs every 15,000 miles.
