What You Need To Keep Your Tranny Happy
Life with an automatic transmission is like dating a high-maintenance supermodel: awesome to be around when everything works out and the mood is good. She can make you feel like a million bucks as heads turn to watch her pass, but when you show her even the slightest sign of neglect, she becomes a stubborn mule, unwilling to do even the simplest of tasks. That’s because automatic transmissions are complex and require constant preventive maintenance to keep them happy. As such, we’ve assembled a buyer’s guide to assist you with preserving the relationship you’ve come to depend on between you and your automatic transmission. Enjoy.
What is it: Low-profile pan for Jeep automatics
Why it’s cool: The cast-aluminum pan for the 42RLE transmission has a low profile to assist Jeepers with clearance issues associated with skid plates, exhaust routing, and aftermarket crossmembers. The finned design helps expel heat while a magnetic drain plug allows for easier ATF changes. The unit holds an additional quart of fluid over stock and is available with a black or raw finish.
Information: PLM, 800/335-4345
What is it: Max ATF
Why it’s cool: ATF is the lifeblood of your transmission. In off-road driving scenarios, it can get extremely hot and oxidize, which greatly diminishes performance. Max ATF is a fully synthetic formula that is able to withstand high heat without oxidizing. This dramatically reduces wear and tear on transmission parts.
