DOES IT HELP OFF-ROAD?
IF YOU’RE after a serious improvement in off-road ability, you might be a little disappointed. A transmission remap is about getting the auto to work how it should from factory. The problem is, most autos are near-on perfect already at slowspeed work. The torque convertor slipping is a positive thing that acts like reduction gears. As the torque convertor slips, you’re able to get the engine making peak torque while still keeping wheel speed low.
In some situations, like steep descents, momentarily locking the torque convertor can give you more engine brake; but the best off-road modification for an auto slush-box is still a large external cooler to keep temperatures under control.
That said, if you’re racking up the kays doing serious touring or towing, these modifications can save you huge amounts at the fuel bowser, and with lower running temperatures will make towing in hot conditions less of a concern. Both your wallet and peace of mind will benefit.
Paul did offer a little caution for people heading to their local Facebook tuner. “It’s very easy to stuff up,” he said. “There are countless hours in figuring out what does what, and getting it wrong can make the transmission perform worse than stock.”
