I'm at 45k miles now and I'm planning ahead on getting my transmission fluid replaced around 60k miles.
I searched and it seems pretty tedious. The transmission has to be at the right temperature for you to fill up the fluid properly.
My questions are:
1) I'm thinking I should just bring it to the dealer. How much will this cost? I'm estimating about $300-$400. Could this be done for less? I'm in Orange County, CA. If you're local, do you have any recommendations where I can get this done properly for a good price?
2) Why can't I simply drain the fluid, measure exactly how much (i.e., fill it up in a milk gallon jug), then proportion the amount of new transmission fluid in a 2nd milk gallon jug to the exact same level, maybe a hair more just to be safe and pump that into the transmission? Would this be difficult? I wouldn't even have get the temperature right or anything if I'm simply putting back the same amount that came out. Am I over simplifying this process? Is it not worth the risk of messing this up and ending up with a catastrophic failure of the transmission?
