Breather Extension Kit for AT (automatic transmission). This kit is essential equipment when driving where the automatic gearbox may be submerged in water, such as when crossing a river or passing through a large water hazard.
For Jimny JB74, 64 MT (manual transmission) vehicles, the breather valve is extended with a hose from the transmission gearbox to a height near the engine. For the AT (automatic transmission) Jimny, however, the plug is located directly on the automatic gearbox, so there is a high risk of water entering the automatic gearbox when it is submerged in water. The automatic gearbox is a delicate piece of machinery and may be damaged in the worst case if water gets mixed into it.
To overcome these issues, we recommend this breather extension kit which acts similar to snorkels. This product includes an 80cm silicone hose, and the valves can be relocated above Jimny's floor level, such as the top of the engine bay (just under the bonnet). It allows the automatic gearbox to breathe with changes in temperature and atmospheric conditions even if the automatic gearbox is submerged in water. They are ideal products for off-roading where the automatic gearbox is submerged in water.
This product comes with an 80cm silicone hose, a valve, and six cable ties. Three hose colors are available: red, blue, and black.
* These Kits are high-quality products and have a proven track record that we can trust. However, please note that it does not guarantee 100% water ingress prevention. We recommend changing the automatic transmission fluid (ATF) regularly.
* This product is the manufacturer's stock, and the orders may take several days or more to ship.
