I am sure my Corolla is well due for a transmission fluid change. Seeing as the previous owner changed the fluid at 177k , I believe changing the fluid should not be a problem, as the fluid has been changed recently enough that I think I do not have one of those "don't change the fluid" cars on my hands. I am quite busy lately and do not have time to change the filter, I am considering draining and filling the transmission and then changing the filter and gasket maybe 5-10k from now. Which transmission fluid and filter do you recommend ? I would like to buy something off ebay or amazon.
Many cars call for inspecting transmission fluid at 30,000mi. or longer intervals and changing when it shows signs of aging. At 60,000mi. it seems due for a change, but unless it's seen heavy duty service it's unlikely to be aged to the point where you need to worry about hurting the transmission by changing it. I've changed much older, coffee colored fluid on used cars I've purchased without encountering problems.
Start by draining the pan and, if it's not too difficult (rusted bolts, etc.) removing and cleaning the pan, magnets and cleaning or replacing the filter screen if necessary. After replacing the pan (and gasket), refill with the quantity you drained and drive it a bit, rechecking and correcting level every few minutes until it's stable and you've done what most people do - this changes perhaps half the fluid. You might want to repeat this in maybe 10,000mi., sooner if the fluid looks bad., thereafter reverting to regular intervals.
After doing the above, I prefer to also change out the old fluid remaining in the torque converter by opening the line between torque converter and cooler at the radiator and running the engine to pump the old fluid out while pouring new in, pausing as needed to correct fluid level and stopping when the fluid coming out looks new. This is a busy process and it's good to have a helper to start and stop the engine while you keep an eye on levels. Because some mixing of new and old fluids is unavoidable, the entire process requires 2-3qt. more than the listed capacity of the whole system.
