    Hi guys, I got a 2003 4Runner 4x4 SR5 V6 and I'm currently replacing ALL my transmission cooler lines and I'm wondering if there are any alternatives to the OEM rubber hoses.

    I'm curious to see if anybody found this rubber hose in bulk/cut to length, if so what are the specs on it? I'm referring to the rubber hoses between both sets of hardlines and the radiator in the pic below:

    When i upgraded my trans cooler used this exact line: https://www.amazon.com/Hayden-Automotive-106-Transmission-Cooler/dp/B000HE6H3S/
    It worked perfectly since doing the swap in 2019. Biggest thing to pay attention to is the internal diameter of the hose, as you dont want to happen to get something narrower than what you currently have and create a flow restriction. Pretty sure its 3/8" ID, but probably double check with some calipers.

    OMG that is EXACTLY what I was looking for! Thank you so much. That 4 ft section is cheaper than 1 of those rubber hoses from the dealership.
