5HP30 Transmission Filter Change

he could also just flip the thing over and pour it right in.

Yeah, I suppose I could just flip it over and pour, but my unflipper is broken

I changed my tranny with Royal Purple MAX ATF. it works. The 14mm hex socket is somewhat of a odd size tool. I got a set of larger hex socket from harbor freight tools.

I just bought a 14mm allen wrench and cut an inch of it off and used it in a socket...not bad for 2.99

Yep, even with a standard 14mm allen-head socket I had to hack a piece of the hex section off to squeeze it into place on the drain plug -- space is tight down there.

Stargazer, I did not do this myself, but you could conceivably drain and fill the pan over the weekend, drive the car for a week or so and then pull the pan next week (or in a reasonably short time) to replace the filter and do a second fluid swap. You're going to want to change fluid at least twice anyway to get out as much old fluid as possible.

BTW, look for minor leaks at the wiring harness plug and selector shaft seals. They could get worse when the new fluid is trying to get out.

In fact, that's an excellent reason to do a drain and fill now -- if you find leaks afterward, you can chase them down without having to drop the pan twice.

Oh, I didn't think of the potential for leaks at the seals on the side. Thanks for that heads up!

Did you do the fill twice like you are describing? If so, how much fluid did you use? I have 7 litres now, but can get more easily enough. I just don't want to run out.

If that 14mm is as tight as the ones on the differential, I've got that covered with an allen wrench that's been heated and bent. I used a box-end wrench on it to break it loose. Man, that was tight!

I hit up Harbor Freight the other day for a set of Torx sockets and other stuff that I needed, so I'm pretty well covered in the tool box. I have a set of bits for a ratcheting screwdriver but I didn't trust those with the pan bolts.
