What solvent's best to clean AT pan of varnish?

[cjcride]

Going to do a AT pan off drain and fill on a 150,000 Km/94,000 Mi 2008 Corolla.
What is a good solvent to quickly clean off the varnish in the pan?
Thanks in advance.

Acetone

 

[oilpsi2high]

Literally any degreaser.

Brake cleaner.

Brake Cleaner......any kind, and Cheap!
That's what I used on the 2006 Corolla.

I've never seen a transmission pan develop varnish on the inside.

+1 I have never seen a heavily varnished pan but brake cleaner should break it down just fine. If not I would use mineral spirits or acetone then blast it with brake cleaner

Same - just gunk you can wash out with WD40 ...

Me neither.
Sludge, yes.
Never Varnish.

I've always just used the power washer (yep, plain water) then let air dry. I worked at a transmission shop in the late 80's - just a power washer was used for all cleaning jobs.

Varsol, Stoddard Solvent or plain old mineral spirits. Kerosene will work just as well. If you have anything more than residual ATF deposits, you have a problem or lack of ATF drain/refill (which is all you need).

Brake cleaner
Pressure washer
Brillo pad

Agree, next choice, mineral spirits.

I used carb cleaner one time and gas another. Whichever is cheaper and easier to reach.

Does ATF varnish though?

And your Corolla has a drain plug, so a pan drop isn't necessary

 

[cjcride]

It's a new to me 2008 Corolla. I'm going to give it the Bitog Blitz. Change engine oil & filter, AT oil & filter, coolant change and brake fluid flush.
It's one lucky puppy.

Brillo pad and a hot water rinse. Brake clean is bad to get on you or in you.

I've always used acetone as my cleaner of choice for brake jobs for this reason, and would probably use it to clean an AT pan as well.
