2500 Allison Trans. Filter Question
I'm getting ready to start a 2500mi road trip and just realized that the spin on transmission filter requires changing. I don't have time to get the coach in to have it done so am going to have to do it myself. I bought the filter, filter wrench, and a gallon of trans-syd. It looks pretty straight forward, the mechanic where I bought the supplies reminded me to clean the magnet and to fill the new filter prior to installing. Is there anything else I should be aware of? How much fluid should I expect to lose? being that the pan is lower than the filter I'm hoping just what is in the filter. Any tips or advice would greatly appreciated. Thanks in advance...
