how to install transmission cooler on manual transmission

Plate and fin coolers are commonly used these days and act like a mini radiator for the transmission. It will decrease damage during intense situations, which in turn will lengthen the life of your transmission. It’s like a smaller radiator, cooling the ATF before it returns into the transmission. To prevent this from happening, an auxiliary transmission cooler can be installed. This additional heat causes the transmission fluid to break down, reducing its ability to perform smooth gear changes as well as causing irreversible damage to the transmission. However, if you add more strain to the gearbox, for example, when towing, if your car is loaded with accessories, long inclines, beach driving or hot summer days, then components have to work harder, which creates more heat than the stock transmission cooler is designed to handle. Under normal conditions, this would sufficiently cool the ATF before it gets re-circulated back into the transmission. This heat gets released as the transmission fluid passes through a cooling chamber at the bottom of the radiator. Like engine oil, automatic transmission fluid (ATF) absorbs the heat produced by moving internal parts. The impact this will have on transmission temperatures is not rocket science. Regular stock transmission coolers work by using the vehicle’s radiator, which is usually hot.

Your transmission can never run too cool (unless you’re in the snow). Overheating is the main cause of transmission deficiency, accounting for around 90 per cent of all failures. Transmission’s worst nightmare – towing on sand on a hot day What you need to know
