I have a 2005 camry. I’d drain the fluid, drop the pan, change the trans filter and then refill with castrol import trans fluid. The problem is the 2005 camry has like 3 transmissions and the after market filter I bought at Pep Boys fit the gasket but not the filter. Another kit fit the filter and not the gasket so I had to buy both. Cost $60. Castrol is $5 a quart and that’s 20 bucks. Get an offset wrench to get at 2-3 bolts on the left side that is tight. Will take you 3 hours max. Have fun. It’s easy and you’ll know it was done right. I change my fluid every 9K and the filter 30-50K.
